[PATCH v2 0/2] Fix /proc/*/stat parsing

[Martin Kletzander]

While working on some polkit stuff I found out that we are inconsistent with the
way we parse /proc/*/stat files, so I added a new helper instead along with some
tests.  Unfortunately using it for the thing I wanted is not really viable in
the end, so it "violates" the Rule of three, but at least it does something
correctly.

v2:
- Fixed open64 by just using virFileReadAllQuiet instead of g_file_get_contents
- Removed some leftover unused variables
- Still do not know why my cirrus builds fail

v1:
