Currently, we write each file to the command line, but this can result in
situations where the number of files passed exceeds OS imposed command
line limits. For compilers, we solve this with response files. For
depscan I've chosen to use a JSON list instead. JSON has several
advantages in that it's standardized, there's a built-in python module
for it, and it's familiar. I've also chosen to always use the JSON file
instead of having a heuristic to decide between JSON and not JSON,
while there may be a small performance trade off here, keeping the
implementation simple with only one path is wort it.

Sonarcloud.io only can read the sonarqube based report that gcovr can
produce. This change enables support for this output in meson and
ninja.

For an ELF targets, shared_module() builds a module with SONAME field
(using -Wl,-soname argument). This is wrong: only the shared_library()
needs SONAME, while shared_module() does not. Moreover, tools such as
debian's dpkg-shlibdeps use presence of SONAME field as an indicator
that this is shared library as opposed to shared module (e.g., for the
module it is okay to have unresolved symbols which are imported from
the executable which loads the module, while a library should have all
symbols resolved).
This was in fact already the behavior on Darwin; extend it to ELF
targets as well.

Currently all arguments are being passed to scan-build as part of the
refactoring of how Meson internally handles arguments, but that's wrong,
only project specific arguments are supposed to be passed.
Fixes: #8818
This is a follow-up to gh-8706, which contained the initial fix
to ninjabackend.py but somehow lost it. This re-applies the fix
and adds a test for it.
Without the fix, the error is:
ninja: error: 'ct2.pyx', needed by 'libdir/ct2.cpython-39-x86_64-linux-gnu.so.p/ct2.pyx.c',
missing and no known rule to make it
When mutable items are stored in an lru cache, changing the returned
items changes the cached items as well. Therefore we want to ensure that
we're not mutating them. Using the ImmutableListProtocol allows mypy to
find mutations and reject them. This doesn't solve the problem of
mutable values inside the values, so you could have to do things like:
```python
ImmutableListProtocol[ImmutableListProtocol[str]]
```
or equally hacky. It can also be used for input types and acts a bit
like C's const:
```python
def foo(arg: ImmutableListProtocol[str]) -> T.List[str]:
arg[1] = 'foo' # works while running, but mypy errors
```
...Update 2, to be exact, since the Visual Studio linker only gained the
`/WHOLEARCHIVE:` feature since Visual Studio 2015 Update 2.
This checks whether we have the corresponding `cl.exe` which is
versioned at or after Visual Studio 2015 Update 2 before we try to apply
the `/WHOLEARCHIVE:xxx` linker flag. If we aren't, use built-in methods
in Meson to grab the object files of the dependent static lib's, along
with the objects that were `link_whole:`'ed into them, and feed this
list into the linker instead.
This would make `link_whole:` work on Visual Studio 2015 Update 1 and
earlier, including previous Visual Studio versions.
When pch are used for a target meson will make the compiler to include
the pre-compiled header. While this is useful, this needs to happen
before any other header has been included, otherwise:
1) we won't take advantage of pch for anything else previously included
2) gcc will just fail as it won't even try to look for a pre-compiled
header in this case [1]
This case can happen quite a easily when a dependency provides an
included header in its cflags.
As per this, split _generate_single_compile() in two phases, one is
responsible of initializing the compiler data, while the other is
defining commands for the context.
In this way, when pch can be used, we can insert the pch inclusion
earlier than any other provided by the target.

Even if the command is not wrapped by meson, it could have been modified
to add java/mono interpreters. This fix potential inconsistency between
wrapped and unwrapped commands.
