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.

Move to a function the code generating the package name from a
symbol's name, to avoid code duplication.
This is not used currently, but will be in a subsequent patch.

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.
A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

Python saves a pre-compiled support/scripts/kconfiglib.pyc file
side-to-side with the corresponding .py file.
This does not work if the Buildroot source tree is read-only (but
this is not an error for Python, which keep going OK).
But this may cause issues for out-of-tree builds in case the same
Buildroot source tree is shared by many builds.
Also, 'make clean' currently does not clean this file, and out-of-tree
builds can remove it either, at the risk of causing issues for other
out-of-tree builds running at the same time.
Just tell Python not to generate .pyc files:
- call the script via python, don't use the sha-bang
- thus, make the script non-executable, and remove the sha-bang
