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()
* Use _get_callee_args to unwrap function call arguments, needed for
module functions.
* Move some FeatureNewKwargs from build.py to interpreter.py
* Print a summary for featurenew only if conflicts were found. The
summary now only prints conflicting features.
* Report and store featurenew/featuredeprecated only once
* Fix version comparison: use le/ge and resize arrays to not fail on
'0.47.0>=0.47'

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:

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.
If the external program is a string that is meant to be searched in
PATH, we can't add a dependency on it at configure time because we don't
know where it will be at compile time.
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
This is accepted by all other binaries in the cross file. With this
change, we also don't check whether the specified command exists at
configure time, but that's probably a feature anyway.

* Add a test case for bad de-dup of -framework args
https://github.com/mesonbuild/meson/issues/3800
* pkgconfig: Don't naively de-dup all arguments
Honestly don't know what I was smoking. Of course the `Libs:` field in
a pkg-config file can have arguments other than -l and -L
Closes https://github.com/mesonbuild/meson/issues/3800
* pkgconfig module: Fix needlessly aggressive de-dup
When find_library is used to find dependencies, meson checks all paths for
libraries with all prefixes that could match. This means that when we are
compiling with -m32 on a 64-bit system, meson will find 64-bit libraries and
assumes that they will work. Naturally that is not the case.
The obvious fix is to do a test link against those libraries, but the extra
wrinkle here is that we need to do a "whole link" so as to test the static
libs. A check with gcc+ld on linux shows that unless there are unresolved
symbols from the main.c file, the static library is never checked so we avoid
the error from an incompatible library.
Currently the former will be parsed as [''], while the latter is parsed
as [] in python. This makes for some obnoxious special handling
depending on what the user passes. This is even more obnoxious since for
string type arguments this doesn't require special handling.
The name splitting was wrong and would not incorrectly handle folders
with two dots, like Foo.framework.dSYM and treat this as 'Foo' instead
of 'Foo.framework', which would lead to meson detecting dSYM bundles
as frameworks and try to use those like a framework, which is wrong.
Fix#3793
We mention this is equivalent to setting both build_by_default and
build_always_stale in the release note, and in the warning emitted when it's
used, but not in the reference manual.
ninja chokes when building FFmpeg's static libraries, as the
command line can be larger than 32000.
This was disabled on purpose in #1649, but the rsp syntax was
different: this commit makes it so the options and output file
are still passed on the command line, gcc-ar didn't work
otherwise.
