We can't know if the .lib is a static or import library, but that's
a problem in general too. The only way to figure out if a specific
file is an import or a static library is to dump its symbols and check
if it starts with __imp or not.
Even then, some libs are hybrid import and static, i.e., they contain
references to DLLs for some symbols and also provide implementations
for other symbols so this is a difficult problem.

As the Vala compiler does not define thread_flags() and
thread_link_flags(), depending on threads in any capacity will cause Meson to
fail.
Fixes#2720.
We can now specify the library type we want to search for, and whether
we want to prefer static libraries over shared ones or the other way
around. This functionality is not exposed to build files yet.
Auto detection was based on parsing gcc's output so we have to
ensure that it is always 'C'.

This method accepts a single function that takes no arguments and
returns a single value which can be a value that can be cast to
a 64-bit signed integer, or a string, and returns that value.
Mostly useful for running foolib_version() functions that return the
currently-available version of libraries.
Of course D compilers have different flags to set some important
D-specific settings. This adds a simple method to change these flags in
a compiler-agnostic way in Meson.
This replaces the previous `unittest_args` method with a more generic
variant.
In version 3.6.0, clang added -Wignored-optimization-argument. Without
setting this flag to -Werror, "ignored optimization arguments" such as
(for example) -fpeel-loops, are accepted but warned about, leading to
noisy builds if meson thinks the flag is supported.

CCache requires this flag when building with precompiled headers.
Without it, the preprocessor fails and CCache fallbacks to running the
real compiler.
Users still need to set 'sloppiness' to 'pch_defines,time_macros' in
their ccache.conf file for CCache to cache builds that use precompiled
headers. See the CCache manual for more info:
https://ccache.samba.org/manual.html#_precompiled_headers
In addition to filtering libs out while generating the command-line, we
must also filter them out in find_library() otherwise these libs will be
detected as "found" on Windows with MSVC.

This commit amends 04a2e6de making
linker.get_std_shared_lib_link_args() always return -shared for
SharedLibrary(es) instead of -bundle. SharedModule(s) get linked with
linker.get_std_shared_module_link_args() which already correctly returns
-bundle.
Before this change -bundle and -install_name ended up being emitted
for Objective-C shared libraries, which caused a linking error.
