44a5c46213 manual/user guide/customization: rework section on rootfs customization
This patch reworks the section on root filesystem customization as follows:
- use labeled list instead of bulleted list to clarify the different methods
- move rootfs overlay and post-build scripts to the top and label them as
  recommended.
- split post-image to a separate section, as it is not related to the target
  filesystem customization
- line up post-build and post-image explanations, for example regarding
  working directory of the script
- general expansion of some of the explanation
- general rewording

9c09fc6017 manual/user guide/customization: add section with recommended dir structure
Although the user is free to choose where to put project-specific files, the
presentation 'Using Buildroot for real projects' [1] first described a
certain recommendation.
This patch briefly describes this recommendation in the form of a directory
structure overview, the details will be added in subsequent patches.

Since the section on BR2_EXTERNAL is logically connected to the directory
structure, this section is moved right after it.

77007ad950 manual/user guide: high-level restructuring
This patch performs some additional restructuring of the manual,
specifically in the User Guide. In detail:

- Rename 'Daily use' to 'General Buildroot usage'
- Move chapters 'make tips', 'Eclipse integration', and 'Advanced usage' as
  sections under the 'General Buildroot usage' chapter.
- Rename 'Details on Buildroot configuration' into 'Buildroot configuration'
- Rework the 'Customization' section as follows:
  - Move the short section on debugging the external toolchain wrapper into
    the rest of the explanation on external toolchains.
  - Remove the now redundant section on toolchains, as this is already
    explained in much more detail in the 'Buildroot configuration' chapter.
  - Move the sections on busybox/uclibc/kernel configuration from chapter
    'Customization' into a separate chapter 'Configuration of other
    components'.
  - Rename the remaining part of the original 'Customization' chapter into
    'Project-specific customization' and fold it together with the next
    chapter 'Storing the configuration'
- Remove the chapter 'Going further in Buildroot innards' thanks to:
  - Moving the chapter 'How Buildroot works' to the Developer guide.
  - Moving the 'Advanced Buildroot usage' section to the 'General Buildroot
    usage' chapter.
- Remove the chapter 'Hacking Buildroot' by:
  - Adding a reference to adding packages to the 'Project-specific
    customizations' chapter
  - Leaving out the explicit reference to creating board support, as this is
    part of the previous chapter already, so an extra reference is
    redundant.

569db40574 manual: high-level restructuring
The structure of the buildroot manual is not always clear. There is a large
number of chapters, and some chapters seem to overlap. The distinction
between general usage and developer information is not always clear.

This patch restructures the manual into four large parts:
- getting started
- user guide
- developer guide
- appendix

Except for the names of these parts, the section names are not yet changed.
Content-wise there are no changes yet either. This will be handled in
subsequent patches.

In order to achieve the introduction of a new level 'parts' above
'chapters', the section indicators (=, ==, ===, ...) of several sections
have to be moved one level down. Additionally, the leveloffset indication to
asciidoc has to be removed. Finally, to maintain more or less the same level
of detail in the table of contents, the toc.section.depth attribute is
reduced as well. Note that for some sections, less detail is visible now.

For URLs where no link text was provided, the display becomes:

dd935d6771 gendoc infra: use $(pkgname) instead of explicitly passing 'manual'
In the gendoc infrastructure, using an assignment of the form
    FOO = docs/$(1)/bar
inside GENDOC_INNER does not work as expected: the $(1) value is empty here
and the value of FOO becomes 'docs//bar'.

Parameters $(2), $(3), etc. do not have this problem. The specific thing
about $(1) is that it is a parameter to GENDOC itself (indicating the
document to create) and passed transparently to GENDOC_INNER.

This is different from the package infrastructures, where $(1) is set from
$(pkgname). In fact, the same strategy could be used by the gendoc
infrastructure as well, as $(pkgname) resolves to 'manual' for file
docs/manual/manual.mk. This has the advantage that the described problem
does not occur.

Note that this means that if we want to use the same GENDOC infrastructure
for another document, it will have to reside in a separate directory than
the manual.

a930d9cef6 toolchain: linker options with a $ sign are not supported
As reported in bug #7172 [0], setting BR2_TARGET_LDFLAGS to a value
containing a $ sign can lead to unexpected results.

This is because it is very hard to know when the $ sign gets evaluated:
  - in the Buildroot-level make
  - in the shell called by the Buildroot-level make
  - in the package's own build-system, either at configure time, in the
    Makefile, in a shell in the Makefile...

So, it is very difficult to know how much escaping that would need.

A proposal is to use a shell variable to pass such values unmolested.
But it is not that simple either, since it still contains a $ sign, and
there is not much certainty as to when it would be evaluated.

Instead, just document this limitation, both in the help text for
BR2_TARGET_LDFLAGS, and in the known-issues section in the manual.

Does not really fix #7172, but at least the limitation is documented.

54456cc698 infra: consistently use double dollar signs inside inner-xxx-targets
The inner-xxx-targets in the buildroot package infrastructures are
evaluated using $(eval) which causes variable references to be a bit
different than in regular make code. As we want most references to be
expanded only at the time of the $(eval) we should not use standard
references $(VAR) but rather use double dollar signs $$(VAR). This includes
function references like $(call), $(subst), etc. The only exception is the
reference to pkgdir/pkgname and numbered variables, which are parameters to
the inner block: $(1), $(2), etc.

This patch introduces consistent usage of double-dollar signs throughout the
different inner-xxx-targets blocks.

In some cases, this would potentially cause circular references, in
particular when the value of HOST_FOO_VAR would be obtained from the
corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test
is added to check for a host package (the only case where such constructions
are relevant; these are not circular).

Benefits of these changes are:
- behavior of variables is now again as expected. For example, setting
  $(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while
  originally it would cause very odd results.

- The output of 'make printvars' is now much more useful. This target shows
  the value of all variables, and the expression that led to that value.
  However, if the expression was coming from an inner-xxx-targets block, and
  was using single dollar signs, it would show in printvars as
    VAR = value (value)
  while if double dollar signs are used, it would effectively look like
    VAR = value (actual expression)
  as is intended.
  This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME,
  FOO_SITE_METHOD and FOO_MAKE.

The correctness of this patch has been verified using 'make printvars',
'make manual' and 'make legal-info' before and after applying this patch,
and comparing the output.

4cce4ac990 graphs/depends: do not draw transitive dependencies by default
The transitive dependencies make the graphs barely readable for large
configs, with a large number of packages.

So, just switch to not drawing the transitive dependencies by default.

By popular demand... ;-)

07c642b735 docs/manual: add the virtual packages list
Add the list of virtual packages as an appendix to the manual.

Also reference this list from appropriate locations elsewhere in
the manual:

  - in section 7.2.2. "Config.in file", after the existing explanations
    on dependencies on target and toolchain options, on a linux kernel,
    and on udev /dev management,

  - in section 7.2.10. "Infrastructure for virtual packages", in the
    provider Config.in and .mk explanations, to have the list of existing
    symbols to select (in Config.in) and packages to provide (in .mk).
