Move database handling utility functions
Move splitname, checkdbdir, get_pkgpath into db.{h,c} as these will be needed to parse both the local and sync databases during the initial splitting. They will be moved out of db.{h,c} at to more appropriate locations at a later stage. Signed-off-by: Allan McRae <allan@archlinux.org>
