The /bin, /sbin, /lib, /lib32, /lib64, /var/run symlinks should never be removed
in Void, so be safe and ignore the removal of them.
Added another test to the testsuite to verify its correctness.
There was another case where it now was failing: "fs-utils-v1.00_1".
Previous code didn't take into account that a valid version might also
contain a non digit after '-'.
Added more tests to the testsuite to verify its correctness.
Make xbps_pkg_{name,version} return NULL if next character
after the last '-' character is not a digit, and if there's a digit
make sure that there exists a '_' character too.
Added more tests to the testsuite to catch this. With these changes
'python-e_dbus' is properly detected and validated.
Previous code incorrectly found obsolete files in this case:
(curpkg) - in files: /etc/foo.conf
(newpkg) - in conf_files: /etc/foo.conf
and removed this file because the code couldn't find it in the same
array. The new code fixes this case and compares the whole pkg filelist.
1- We can cache the result of the first xbps_pkgdb_init() when it fails
and avoid the malloc/free/access from it.
2- We cache the uname(2) result into a private var in xbps_handle and
use it in xbps_pkg_arch_match().
This improves performance by ~5% approx and it's close as it was before
introducing the repository index format 1.5.
