On Linux, do a readlink on /proc/self/exe (if it exists), and
g_get_dirname() on the result.

On other Unixes, don't know. Some might have something like
/proc/self/exe. Otherwise look at argv[0], and if it doesn't contain a
directory already (possibly relative) look for the executable in
$PATH, etc. Note that this method is trivial to spoof, so it shouldn't
be used for anything that might have security consequences.

On Windows, do GetModuleFileName() on the result of
GetModuleHandle(NULL). If you want to be really correct, use the wide
character version (and then convert pathname from UTF-16 to UTF-8
before passing to g_open() etc.)
