- replace all hardcoded strrchr functions (used to get extension / file name only) with path helper functions (found a few bugs in the process) - split VFS-independent path helper functions into lib/path_util (allows including by other files without pulling in entire VFS) - renamed pp_* functions path_package_* - split remaining path helper functions into lib/res/file/path - vfs: split should-reload logic out of vfs_reload_changed_files - lib: add comments to rand/xrand This was SVN commit r3796.
