pacsort: parse inputs up front into control struct
This moves most of the parsing work out of the sorting path. The explode and splitfile functions now call input_new and append input_t structs to the list of sort candidates instead of raw strings. This lets us make smarter and easier decisions in the sorting callbacks, which are now also split into the version and file comparison methods for clarity. This fixes two bugs: 1) Incorrect ordering with filenames containing epoch in the pkgver 2) Incorrect ordering with package names which are substrings of each other (e.g. "systemd" and "systemd-sysvcompat"). Performance of the --files mode degrades slightly as a result of this change, but not unreasonably. Sorting with small inputs (5-10) doubles in runtime, but larger inputs (4000+) only increase by 20%. ref: https://bugs.archlinux.org/task/37631 Signed-off-by: Allan McRae <allan@archlinux.org>
