This patch exploits the information residing in ltversion to set the
-compatibility_version and -current_version flags that are passed to the
linker on macOS.
GNU LD does not use soname when linking a PE/COFF binary, so it makes no
difference, but it breaks when using the llvm linker (lld), which does
not support the soname flag when building PE/COFF binaries for Windows.
Fix#3179
This caching is only for a single run, so it doesn't help reconfigure.
However, it is useful for subproject setups where different subprojects
will run the same compiler checks.
The cache is also per compiler instance and is not used for functions
that want to read or run the outputted object file or binary.
For gst-build, this halves the number of compiler checks that are run
and reduces configuration time by 20%.

- Updating ARMCCompiler constructor in c.py to raise error as per comments
According to Python documentation[1] dirname and basename
are defined as follows:
os.path.dirname() = os.path.split()[0]
os.path.basename() = os.path.split()[1]
For the purpose of better readability split() is replaced
by appropriate function if only one part of returned tuple
is used.

Otherwise we will try to use the objc compiler when linking projects
with both objc and C++.
Technically we should use the objc++ linker when doing this, but on
most (all?) systems the objc++ linker is `c++`, which is the same
as the C++ linker.

See issue #2762
Adds full_version to class Compiler. If set full_version will be printed
additionally.
Added support for CCompiler and CPPCompiler
Added support for gcc/g++, clang/clang++, icc.
Auto detection was based on parsing gcc's output so we have to
ensure that it is always 'C'.

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.

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.
