FreeBSD 5.0 was released in 2003.
We really do not need to check that we're on >= 4.4.

There's not yet any users of this function on Windows, but it prints a
warning during builds, and seems easy enough to implement. So let's add
a trivial implementation.

<sys/param.h> is required for NetBSD version detection,
and __NetBSD__ must be used to detect even on older releases.

program_invocation_name and program_invocation_short_name are both GNU
extensions. I don't believe one can exist without the other, so only
check for program_invocation_name.

We consider it acceptable, but let's still document it in case people
notice it and are not sure why it's there.

Some programs start with the path and command line arguments in
argv[0] (program_invocation_name). Chromium is an example of
an application using mesa that does this.
This tries to query the real path for the symbolic link /proc/self/exe
to find the program name instead. It only uses the realpath if it
was a prefix of the invocation to avoid breaking wine programs.

For some reason wine will sometimes give us a windows style path
for an application. For example when running the 64bit version
of Rage wine gives a Unix style path, but when running the 32bit
version is gives a windows style path.
If we detect no '/' in the path at all it should be safe to
assume we have a wine application and instead look for a '\'.

On windows process.h is a system provided header, and it's required in
include/c11/threads_win32.h. This header interferes with searching for
that header, and results in windows build warnings with scons, but
errors in meson which doesn't allow implicit function declarations. Just
rename process to u_process, which follows the style of utils anyway.
