In gcovr 3.1 the -r/--rootdir argument changed meaning causing
reports generated with gcovr 3.1 to not find the source files
and look for *.gcda in the whole source tree rather than the
build dir.
So, detect gcovr version and if 3.1 give build_root to -r instead
of source_root.
Fix exception handling of missing rustc, by making it look like the other
compiler detectors

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.

They now are published by the D Language Foundation, and not Digital
Mars. Therefore, their signature has changed slightly.
(We can not check for 'DMD', because that string appears in every
compiler version output to denote the frontend version used by the
compiler).
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.
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.
Unfortunately, `time.time` and file timestamps are not guaranteed to be
in sync and due to various kernel caches may be different enough to
cause rebuilds to fail [1]. This was masked by older ninja versions that
could not read sub-second timestamps.

PkgConfig automatically removes -L paths from libdirs if the -L points
to a system path. It knows what these paths are by taking this as a
configure option at build time, which the distro maintainers set
appropriately and everything works. This allows one to have two
versions of a package installed, a system and non system, and then
override PKG_CONFIG_PATH to use the non system version, and everything
just works. For non-pkgconfig dependencies (such as LLVM) meson needs to
strip these themselves to avoid breaking the above use case.
As stderr may contain information the user can use to solve the problem with
the gcc installation, it should not be ignore but added to the error message.
The valac binary was hard coded in meson. We now check if VALAC is
defined in the environment, and if it is, use its value as the vala
compiler, if not, we proceed with the hard coded binary name.
MESONINTROSPECT is set when running postconf scripts, which implies that
introspection is possible. But it isn't really possible because coredata
hasn't been written yet. We also still need to make sure to delete
coredata if any postconf scripts fail.
If making a typo, it used to output:
> Cross info file must have either host or a target machine.
This was not useful at all and looked like there could be a file format
error or some other issue with the content. Let's have an appropriate
error:
> File not found: /some/path
This is useful when build_machine appears to be compatible with
host_machine, but actually isn't. For example when:
- build_machine is macOS and host_machine is the iOS Simulator
- the build_machine's libc is glibc but the host_machine libc is uClibc
- code relies on kernel features not available on the build_machine
