Separate be_files into be_sync and be_local
The file be_files.c is "split" to be_local.c and be_sync.c in order to achieve separate handling of sync and local databases. Some basic clean-up of functions that are only of use for local or sync databases has been performed and some rough function renaming in duplicated code has been performed to prevent compilation errors. However, most of the clean-up and final separation of sync and local db handling occurs in following patches. Signed-off-by: Allan McRae <allan@archlinux.org>
