Some compilers that act as linker drivers (dmd and ldc) need to split
arguments that GCC combines with , (ie, -Wl,-foo,bar -> -L=-foo -L=bar).
As such we need to detect that the previous argument contained -soname,
and not wrap that in a --start-group/--end-group
This modifies the shared library test to demonstrate the problem, with a
test case.
Fixes#6359
It may not be obvious to users that these two ways to set build-types
override each other and specifying both is redundant, and conflicts
are resolved based on whichever is specified later.

With the current logic passing `--debug` will actually be parsed as
`-Ddebug=false`, which is absolutely not what is expected.
There is no case in which the presence of a boolean option in `--foo`
form will mean 'I want feature foo disabled', regardless of the
*default* value of that option.
Also includes a test.
Closes https://github.com/mesonbuild/meson/issues/4686
The previous code was assuming that options do not depend on each
other, and that you can set defaults using `dict.setdefault()`. This
is not true for `buildtype` + `optimization`/`debug`, so we add
defaults + overrides in the right order and use the options parsing
code later to compute the values.
Includes a test.
Closes https://github.com/mesonbuild/meson/issues/6752
This ensures that options are always parsed in the order in which they
were specified on the command-line, even with Python 3.5, and
non-CPython implementations compatible with CPython 3.5 and 3.6.

This is needed when mixing D and C code, as it's possible to end up
witha combination of linkers and compilres such that C produces pdb
files but D does not.
This is the argument to name the implib when using the Visual Studio
Linker. This is needed by LDC and DMD when using link.exe or
lld-link.exe on windows, and is really a linker argument not a compiler
argument.
This allows the harness to apply the version correctly, putting it in the right
place, dropping the right amount of numbers, etc.
pdb taking a version allows it to be more easily copied from the
shared_lib type.
[why]
Sometimes one want to set the 'Conflicts:' field in .pc files.
This is possible by using the 'conflicts' keyword argument in the
pkgconfig module. The feature is not documented on mesonbuild.org,
though.
But a warning is issued:
WARNING: Passed invalid keyword argument "conflicts".
WARNING: This will become a hard error in the future.
History:
It has been added along with kwarg 'url' with commit
309041918 pkgconfig: Add missing 'URL' and 'Conflicts' entries
Later the kwargs check has been introduced with
80d665e8d Converted some modules.
but both 'url' and 'conflicts' were missing.
With commit
2acf737b pkgconfig: Document url keyword
the 'url' kwarg has been added to the checks, but not 'conflicts'.
[how]
Add 'conflicts' to the allowed kwargs.

This change made `5 dependency versions` unit test fail because now once
a subproject has been configured, the fallback variable is checked to be
consistent. So it has to use new subproject because 'somesub' was
already configured by previous tests.
Similar to meson.override_find_program() but overrides the result of the
dependency() function.
Also ensure that dependency() always returns the same result when
looking for the same dependency, this fixes cases where parts of the
project could be using a system library and other parts use the library
provided by a subproject.
DMD and LDC are a real pain to use as linkers. On Unices they invoke the C
compiler as the linker, just like meson does. This means we have to figure out
what C compiler they're using and try to pass valid arguments to that compiler
if the D compiler doesn't understand the linker arguments we want to pass. In
this case that means gcc or clang. We can use-the -Xcc to pass arguments
directly to the C compiler without dmd/ldc getting involved, so we'll use that.
This was never really true of the D compilers, it made them more
complicated than necessary and was incorrect in many cases. Removing it
causes no regressions on Linux, at least in our rather limited test
cases).
