From 0909a72000b03332c5203b16b6a4e862c0662e03 Mon Sep 17 00:00:00 2001 From: Allan McRae Date: Wed, 13 Oct 2010 17:55:55 +1000 Subject: 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.
