When dependency(), find_library(), find_program(), or
python.find_installation() return a not-found object and disabler is
true, they return a Disabler object instead.
It is possible for compiler flags to include special characters, such as
double quotes which are needed to define macros with -D options. Since
gtkdoc-scangobj uses shlex.split to split arguments passed to --cc,
--ld, --cflags, --ldflags into lists, we can safely use shlex.quote to
properly quote arguments for these options.
using state.subdir will cause / or \ to be inserted into the target name.
Replace them with @ to future-proof it.

Determine the type of the Windows resource compiler by looking at its
output, not its name.
Also log the name and version of the resource compiler we are using.
When passing static libraries to gtkdoc, they are also appended as
shared libraries to ldflags, which makes the process to fail.
This has been changed to only append shared libraries to ldflags.
Fixes#3935
gtk-doc for autotools has the concept of module version, that is used to define
the module install path and the devhelp2 basename.
Add a `module_version` parameter to gnome.gtkdoc to replicate the same behavior.
Updated the test checking that the install_dir is properly computed (if not
passed), and that the .devhelp2 file has proper name.

gtkdoc-scangobj also accepts compiler arguments. In the same way
that include_directories includes directories, the new c_args
parameter also appends compiler arguments.
One of the gtkdoc's steps calls to gtkdoc-scangobj that also accepts
compiler arguments by using the cflags option.
Compiler arguments from dependencies are also appended now.
As it currently stands, if for whatever reason you have two files you
want to merge with the same output name, it will fail due to multiple
targets with the same name due to the target name being autogenerated
from the output kwarg.

Always honour any windres setting in cross-file (we can't be compiling with
msvc, but this should apply when cross-compiling using gcc or clang)
Always honour WINDRES environment variable
Otherwise look for the resource compiler which is part of the same toolset
as the C or C++ compiler.
Add some commentary on why the conventions for compiled resource file
extensions differ between RC and windres
Also don't try to report non-existent path when we couldn't find the
resource compiler.
The regression was introduced in my recent refactoring of
that method (8377ea4).
This commit simply restores the ordering of the generated
scan_command, ensuring `-lasan` and other internal linker
flags come before `--library` or `--program`
g-ir-scanner is very picky about the flags that it can accept, so the
build fails on macOS if you have Framework external dependencies,
which add -F and -framework arguments.
Also fix incorrect de-duping of -framework arguments for gtkdoc.
* Lookup is now performed according to the following order:
1. use `pkg-config` with `PKG_CONFIG_LIBDIR=LIBPC` from python
2. use plain `PKG_CONFIG_{LIBDIR,PATH}` from the environment
3. try to extract the information from SYSCONFIG
The second step is necessary for relocated python installations
and cross compilation scenarios, where the value of `LIBPC` might
be wrong.
Meson tries to find the interpreter path through the "py" launcher on Windows in all
cases which breaks if meson is run under MSYS2 and an official CPython is installed as well.
MSYS2 Python doesn't install a py launcher which results in meson finding the system one instead
even though python2/python3 is in PATH.
Always check if the interpreter name is in PATH before falling back to checking the py launcher.
* Fix flake8 whitespace reports
$ flake8 | grep -E '(E203|E221|E226|E303|W291|W293)'
./mesonbuild/coredata.py:337:5: E303 too many blank lines (2)
* Fix flake8 'variable assigned value but unused' reports
$ flake8 | grep -E F841
./mesonbuild/modules/gnome.py:922:9: F841 local variable 'target_name' is assigned to but never used
* Fix flake8 'imported but unused' reports
$ flake8 | grep F401
./mesonbuild/compilers/__init__.py:128:1: F401 '.c.ArmclangCCompiler' imported but unused
./mesonbuild/compilers/__init__.py:138:1: F401 '.cpp.ArmclangCPPCompiler' imported but unused
./mesonbuild/modules/__init__.py:4:1: F401 '..mlog' imported but unused
PR #3717 imports ARMCLANG compilers in __init__, but does not add them to
__all__, so they are not re-exported by the compilers package like
everything else.

Mention that Sider runs flake8
Suggest seting flake8 as a pre-commit hook
We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
Those tools use our arguments to build a file and execute it to
introspect it at runtime. However, they do not know that you can pass
the full path to the library to use, and ignore the arguments.
The long-term fix for this is to have them output a .c file that Meson
will build for them, which they can then run, but that will require
upstream changes:

Closes https://github.com/mesonbuild/meson/issues/3774
When an older version of the library being built is installed in the
same prefix as external dependencies, we have to be careful to construct
the linker or compiler command line. If a -L flag from external
dependencoes comes before a -L flag pointing to builddir, it is possible
for the linker to load older libraries from the installation prefix
instead of the newly built ones, which is likely to cause undefined
reference error.
Since the order of dependencies is not significant, we cannot expect
internal dependencies to appear before external dependencies when
recursively iterating the list of dependencies. To make it harder to
make mistakes, linker flags come from internal and external
dependencies are now stored in different order sets. Code using
_get_dependencies_flags are expected to follow the order when
constructing linker command line:
1. Internal linker flags
2. LDFLAGS set by users
3. External linker flags
It is similar to what automake and libtool do for autotools projects.
A number of cases have to be taken care of while doing this, so
refactor it into a helper on ExternalProgram and use it everywhere.
1. Command is a list of len > 1, use it as-is
2. Command is a list of len == 1 (or a string), use as a string
3. If command is an absolute path, use it as-is
4. If command is not an absolute path, search for it
