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.]

The graph-depends script calls make. If the outer make was called
recursively, or if it was called with '-C <somedir>', then the
environment will contain "MAKEFLAGS=w --". Therefore, the recursive
make prints 'Entering' and 'Leaving' messages, which clobbers the

To avoid this, add "--no-print-directory" to the recursive make
arguments. Since we require GNU make 3.81, we can be sure that this

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

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.

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.

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.

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.

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

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

Old toolchains, with old gcc that do not support -print-sysroot, break the
kernel-headers version check script: it fails to find the sysroot of the
toolchain, and thus ends up including the host's linux/version.h.
Most of the time, this will break early, since the host's kernel headers
will not match the toolchain settings.
But it can happen that the check is succesful, although the configuration
of the toolchain is wrong:
- the custom toolchain has kernel headers vX.Y
- the user selected vX.Z (Z!=Y)
- the host has headers vX.Y
In this case, the check passes OK, but the build of some packages later on
will break (which is exactly what those _AT_LEAST_XXX options were added to
avoid).
Fix that by passing the sysroot to the check script, instead of the cross
compiler.
We get the sysroot as thus:
- for custom toolchains, we use the macro toolchain_find_sysroot. We can
do that, because we already have a complete sysroot with libc.a at that
time.
- for internal toolchain using a custom kernel headers version, we just
use $(STAGING_DIR). We can't use the macro as for custom toolchains
above, because at the time we install the kernel headers, we do not yet
have a complete sysroot with a libc.a. But we can just use
$(STAGING_DIR), since we're only interested in the kernel headers.
For all other types of toolchains, we already have the _AT_LEAST_XXX options
properly set, so we need not add a check in this case.
Fixes:

Since we introduced the _AT_LEAST_XXX for the kernel headers, people
using pre-built custom toolchain now have to specify the version of
the kernel headers their custom toolchain uses.
So, when we detect that there is a mismatch between the selection in
the menuconfig, and the actual version of the headers, we currently
only bail out with a terse message "Incorrect selection of kernel
headers".
This could be confusing some, and getting the version of the headers
used by the toolchain is not trivial (well, it's very easy, but not
trivial.)
This patch changes the way we report the error by moving the message
into the test-code, and by printing the expected and actual versions
of the kernel headers.
BUT! To get this pretty error message, we need to run the
test-program, so we can not use the cross-toolchain, we have to use
the native one.
BUT! The native one has its own linux/version.h header, so we can not
simply include it.
So, we ask the cross-compiler where its default sysroot is, and use
that to then force-feed the cross linux/version.h to the native
toolchain.
[Thomas: augment commit log with a message provided by Yann, fix
coding style to not have spaces after opening parenthesis and before
closing parenthesis, reformatted the message "Incorrect selection..."

Of course, if a UID (or a GID) is not defined, it does not have a value,

Ensure the kernel headers version used in the custom external toolchain,
or the manually-specified kernel headers version, matches exactly the one
selected by the user.
We do not care about the patch-level, since headers are not supposed to
change between patchlevels. This applies only to kernels >= 3.0, but
those are actually the ones we do care about; we treat all 2.6.x kernels
as being a single version, since we do not support any 2.6 kernels for
