CMakes `target_link_libraries()` supports certain keywords to
only enable specific libraries for specific CMake configurations.
We now try our best to replicate this for Meson dependencies.
Fixes#9197
Allow methods on the compiler object to receive internal dependencies,
as long as they only specify compiler/linker arguments or other
dependencies that satisfy the same requirements.
This is useful if you're using internal dependencies to add special
"-D" flags such as -DNCURSES_WIDECHAR, -D_XOPEN_SOURCE_EXTENDED or
-DGLIB_STATIC_COMPILATION.
Some CMake packages fail to find at all if no version is specified.
This commit adds a cmake_version parameter to dependency() to allow you
to specify the requested version.
Solaris linker added support for GNU-style --version-script in Solaris 11.4,
but requires adding the -z gnu-version-script-compat flag to enable it.

D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
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.
cmake: get language from Meson project if not specified as depedency(..., langugage: ...)
deps: add threads method:cmake
dependency('threads', method: 'cmake') is useful for cmake unit tests
or those who just want to find threads using cmake.
cmake: project(... Fortran) generally also requires C language
Fortran: check for undeclared variables by forcing implicit none everywhere
C/C++: check for unused parameters and return types
removed unused variables from test cases
ci: do missing return and unused arg check with Github Actions
Solaris doesn't ship static libraries, so the test can't rely on libz.a
existing on Solaris.

The test used by the new define_variable parameter was using the
includedir directory. However, in order to get a successful test,
the includedir variables needs to be relative to the prefix
variable, otherwise the replacemente will not have any effect.
This changes uses the prefix variable itself because we can
assure that it will be present.
pkg-config enables to define variables by using the define-variable
option. This allows some packages to redefine relative paths, so
files can be installed in the same relative paths but under prefix.
This class now consolidates a lot of the logic that each external
dependency was duplicating in its class definition.
All external dependencies now set:
* self.version
* self.compile_args and self.link_args
* self.is_found (if found)
* self.sources
* etc
And the abstract ExternalDependency class defines the methods that
will fetch those properties. Some classes still override that for
various reasons, but those should also be migrated to properties as
far as possible.
Next step is to consolidate and standardize the way in which we call
'configuration binaries' such as sdl2-config, llvm-config, pkg-config,
etc. Currently each class has to duplicate code involved with that
even though the format is very similar.
Currently only pkg-config supports multiple version requirements, and
some classes don't even properly check the version requirement. That
will also become easier now.
