8b691cec63 support/libtool: improve version 1.5 static patching
Alter the libtool 1.5.x support patch to accomodate for wildly different
versions of ltmain.sh
Just make it alter incoming args from -static to -all-static which seems
to apply to all the different variants out there since argument parsing
is unlikely to change much.

97703978ac support/libtool: make -static behave like -all-static
After switching TARGET_LDFLAGS from --static to -static, one issue
appears: from the point of view of libtool, -static only means to link
statically against the 'uninstalled libtool libraries' (i.e the
libraries that libtool has built in the current package), but
otherwise links dynamically with the other libraries. To really get a
completely static build, you need to pass -all-static to
libtool. Unfortunately, -all-static is only a valid option for
libtool, not as a general LDFLAGS, so we cannot to TARGET_LDFLAGS =
-all-static without breaking virtually all packages.

As pointed out 10 years ago on the libtool mailing list, the current
naming of the options is very confusing and the source of issues, and
there was a proposal to change -static to have the behavior of
-all-static, and instead introduce a separate -lt-static to have the
current behavior of -static. But that never got merged, because it was
breaking the current behavior. See:

  http://lists.gnu.org/archive/html/libtool/2004-11/msg00017.html

However, in Buildroot, when we pass -static, we really mean it, and we
want a completely static build. Therefore, this patch adapts our
ltmain.sh patches so that they alter the behavior of -static to make
it work like -all-static. The changes are small and quite easy to
understand, and have been tested to work fine with a small selection
of packages.

11c1076db9 toolchain: add option to copy the gconv libraries
The gconv libraries are used to translate between different character sets
('charsets', even 'csets' sometimes). Some packages need them to present
text to the user (eg. XBMC Gotham).

In (e)glibc they are implemented by the internal implemenation of iconv,
called gconv, and are provided as dlopen-able libraries.

Note that some gconv modules need extra libraries (shared by more than
one gconv module), so we must, when adding a subset of modules, scan the
installed modules in search of the missing libraries.

[Thomas: add general explanation in expunge-gconv-modules and fix
coding style.]

1c7ab72386 support/script/scancpan: add support for BR2_PREFER_STATIC_LIB
Perl extensions are loaded at runtime with dlopen(), so it does not
make sense to even build extensions that are written in C when
BR2_PREFER_STATIC_LIB is enabled. A Perl module written in C or with a
dependency on a module written in C is not available when doing a
static build.

Therefore, this commit adapts the scancpan script to automatically
generate a dependency on !BR2_PREFER_STATIC_LIB when the Perl module
would not work in a static-only configuration.

ebe6154ff4 support/download: fix the git helper
When switching the git helper over to a shell script, a special case was
not carried over: in case the remote has the required reference, we
attempt a shallow clone, using --depth 1. However, this is not supported
when the remote is accessed with the http protocol.

Therefore, the download fails.

What happened before the conversion to a shell script was that the helper
in the Makefile would fallback to doing a full-clone.

This is the case and behaviour that were lost in the conversion.

To avoid making the script too complex, we only attempt a full clone if
needed. And we decide that a full clone is needed by default; we decide
it is unnecessary if the remote has the needed reference *and* the
shallow clone was successful.

84d7986940 support/download: fix the bzr helper
bzr uses the name of the extension of the output file to known what
output format to use: tar, tgz, tar.bz2... If no extension is
recognised, bzr will output to a directory.

Since we use 'mktemp .XXXXXX' to generate temporary files, it obviously
never ends with a recognised extension. Thus, bzr expects the output to
be a directory, and fails since it is a file.

Fix that by forcing the output format.

9bd8b59526 pkg-infra: add possiblity to check downloaded files against known hashes
Some of the packages that Buildroot might build are sensitive packages,
related to security: openssl, dropbear, ca-certificates...

Some of those packages are downloaded over plain http, because there is
no way to get them over a secure channel, such as https.

In these dark times of pervasive surveillance, the potential for harm that
a tampered-with package could generate, we may want to check the integrity
of those sensitive packages.

So, each package may now provide a list of hashes for all files that needs
to be downloaded, and Buildroot will just fail if any downloaded file does
not match its known hash, in which case it is removed.

Hashes can be any of the md5, sha1 or sha2 variants, and will be checked
even if the file was pre-downloaded.

19afad50f5 pkg-infra: don't use DL_DIR as scratchpad for temporary downloads
DL_DIR can be a very precious place for some users: they use it to store
all the downloaded archives to share across all their Buildroot (and
maybe non-Buildroot) builds.

We do not want to trash this location with our temporary downloads (e.g.
git, Hg, svn, cvs repository clones/checkouts, or wget, bzr tep tarballs).

Turns out that we already have some kind of scratchpad, the BUILD_DIR.
Although it is not really a disposable location, that's the best we have
so far.

Also, we create the temporary tarballs with mktemp using the final tarball,
as template, since we want the temporary to be on the same filesystem as
the final location, so the 'mv' is just a plain, atomic rename(2), and we
are not left with a half-copied file as the final location.

Using mktemp ensures all temp file names are unique, so it allows for
parallel downloads from different build dirs at the same time, without
cloberring each downloads.

Note: we're using neither ${TMP} nor ${TMPDIR} since they are shared
locations, sometime with little place (eg. tmpfs), and some of the
repositories we clone/checkout can be very big.

So, use 'chown -h' so even symlinks get properly chowned.

4d922634da support/scripts: generate a list of virtual packages
Generate an asciidoc table that can be included in the manual, that
lists the existing virtual packages, the corresponding symbols, and
their providers (and sub-options thereof).

The core of this change is the addition of a new formatter for virtual
packages. This formatter is a bit tricky, as it has to catter for a
bunch of corner cases:
  - provider is not a package, but is sub-options of a package
  - such a sub-option may be itself 'select'-ed by one or more
    other sub-options
  - legacy packages should not be considered as a provider

Those cases are real:
  - sub-options of mesa3d provide EGL or GLES
  - selected sub-options of mesa3d provide GL
  - udev is a legacy package, but it provides udev

fe696d7c65 support/scripts: introduce a symbol formatter to generate package lists
Currently, we can generate two different tables of packages:
  - a single-column table with the symbols' prompts,
  - a two-column table with the symbols' prompts and locations in the
    menuconfig.

For virtual packages, this is not enough, since we will have to display
more columns, with different content:
  - the virtual package name (but such symbols do not have a prompt)
  - the symbol name
  - the providers for the virtual package

So, instead of having a single function that knows how to generate any
table, introduce a formatter function that is passed as argument to,
and called by format_asciidoc_table(). Such formatter functions are
responsible for providing:
  - the layout of the table (number of columns, column arrangement),
  - the formatted header line,
  - a formatted line for a symbol.

What the formatter should ouput depends on its arguments:
  - if none are passed, the layout is returned,
  - if the header label is passed, it returns the formatted header line,
  - otherwise, it returns the formatted line for a symbol.

Two formatter functions are introduced in this changeset, to replace the
current 'sub_menu' feature:
  - _format_symbol_prompt() to display a one-column table with only the
    symbols' prompts,
  - _format_symbol_prompt_location() to display a two-column table with
    the symbols' prompts and locations.

This will help us to later introduce a new formatter to generate a table
for virtual packages.

[Thanks to Samuel for his pythonistic help!]

b2c75ecc5d support/scripts: who's responsible to decide what is a package
When generating the package lists, the responsibility to decide what is
actually a package symbol is currently split between the _is_package(),
the get_symbol_subset() and the format_asciidoc_table() functions.

The two latter functions check that an item is really a symbol, and that
is has a prompt.

While this is currently correct for real packages, this will no longer
be the case when we also generate a list of virtual packages, since they
do not have a prompt.

Move the responsibility to verify that a symbol is indeed a package symbol
to _is_package(), so it's all in one place, and makes it easier to change
for virtual packages.

f93edd823f support/scripts: do not display virtual packages in generated lists
If a package has both a 'real' and a 'virtual' definition, consider it
is a virtual package and do not display it in the generated package list.

This is the case for jpeg and cryptodev, that are virtual packages, but
also real (but empty) packages used to provide a prompt to enable/disable
a choice to select an implementation. In this case, we do not want to
list the virtual packages, but only their implementations.

So, consider packages that are both real and virtual as virtual packages.

e49d4f0c37 support/scripts: prepare handling virtual packages in generated lists
Prepare to tell apart real packages from virtual packages.

Currently, the code implicitly recognises only real packages, and
discards virtual packages, because of the heuristic used to recognise
whether a symbol is a package:

  - for real package:
    - symbols  : BR2_PACKAGE_FOO
    - .mk files: foo.mk
  - for virtual packages:
    - symbols  : BR2_PACKAGE_HAS_FOO
    - .mk files: foo.mk

The current heuristic is to check for each symbol if a corresponding .mk
file exists, by stripping 'BR2_PACKAGE_' from the beginning of the symbol,
converting the result to lowercase, and checking if a .mk file exists.

So, as a side effect, it completely misses the virtual packages [*], which
is pretty nice since we get a list with only real packages that the user
can indeed select and see in the menuconfig.

[*] Except for 'cryptodev' and 'jpeg' which are both virtual packages and
normal packages. Except they are not normal packages, they are used to
display a choice of the implementation to use. This case will be fixed in
follow-up patches.

Since we'll soon need to also output the table of virtual packages, we
need to teach the _is_package() function to recognise them as well.

This patch is the first step into that direction: it introduces a new
function _is_real_package() that is just a wrapper to _is_package(), which
gains a new parameter, being the type of packages to filter on.

No behavioural change is made in this patch, it is just a preparatory
patch.

47aeebd956 graph-depends: rename the mode constants
This is ugly, since Python does not have enum constructs, so by moving

95ab905ba7 graphs-depends: merge redundant-dependencies elimination
Merge the redundant-dependencies elimination into the newly introduced
transitive-dependencies elimination.

This makes the code cleaner and much shorter, because:

  - the ('all',pkg) redundant dependency is in fact a transitive
    dependency, and we now have code to deal with that

  - the (pkg,'toolchain') dependency is easy enough to deal with that
    having a separate function for that is overkill

67957967a5 graphs: add option to remove transitive dependencies in dependency graph
Currently, all the dependencies of a package are drawn on the dependency
graph, including transitive dependencies (e.g. A->B->C and A->C).

For very big graphs, with lots of packages with lots of dependencies, the
dependency graph can be very dense, and transitive dependencies are
cluttering the graph.

In some cases, only getting the "build-order" dependencies is enough (e.g.
to see what impact a package rebuild would have).

Add a new environment variable to disable drawing transitive dependencies.

Basically, it would turn this graph:

    pkg1 ---> pkg2 ---> pkg3 -------------------.
         |\__________/                 \         \
         |\____________________         \         \
         |                     \         \         \
          `-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8
                    \__________/

into that graph:

    pkg1 ---> pkg2 ---> pkg3 -----------.
         |                               \
          `-> pkg4 ---> pkg5 ---> pkg6 ---> pkg7 ---> pkg8

c8f2d248f6 pkg-cmake.mk: enable ccache for cmake packages
This patch updates the generated toolchainfile.cmake to use ccache.

When toolchainfile.cmake is used inside Buildroot, using ccache during
the build is driven by a CMake knob: USE_CCACHE, automatically set by
the cmake-package infrastructure and reflecting the BR2_CCACHE value.

Since this toolchainefile.cmake file can be used outside Buildroot, and
this file also set a couple of things (among these: the sysroot cflag,
some pkg-config environment variables), it is important to set the
compiler variables as well to keep the consistency of the
cross-compilation configuration.
So, when it is used outside Buildroot, using ccache for the build is
driven by the ccache program availability.

Note that using ccache for the build is achieved by setting the *_ARG1
CMake variables to let CMake use ccache without failing in detecting
the compiler.
