On macOS, we set the install_name for built libraries to
@rpath/libfoo.dylib, and when linking to the library, we set the RPATH
to its path in the build directory. This allows all built binaries to
be run as-is from the build directory (uninstalled).
However, on install, we have to strip all the RPATHs because they
point to the build directory, and we change the install_name of all
built libraries to the absolute path to the library. This causes the
install name in binaries to be out of date.
We now change that install name to point to the absolute path to each
built library after installation.

With this, the default workflow on macOS matches what everyone seems
to do, including Autotools and CMake. The next step is providing a way
for build files to override the install_name that is used after
installation for use with, f.ex., private libraries when combined with
the install_rpath: kwarg on targets.
Because vala is not listed in clike_langs, is_source(fname) is returning False
for Vala source files. Therefore, extract_all_objects() is completely empty
for Vala programs.
Fixes#791
Normally, people would just pass -fembed-bitcode in CFLAGS, but this
conflicts with -Wl,-dead_strip_dylibs and -bundle, so we need it as
an option so that those can be quietly disabled.
This checks not only for existence, but also for usability of the
header, which means it does a full compilation and not just
pre-processing or __has_include.

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.
Closes https://github.com/mesonbuild/meson/issues/2468
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.
