Fix for FS 6404 and functionalize some cachedir handling stuff
In order to best resolve bug 6404, move some cachedir handling stuff out of sync.c and into util.c and create two new functions: filecache_find and filecache_setup. sync.c was rewritten to use these, and alpm_fetch_pkgurl now also uses these routines. Signed-off-by: Dan McGee <dan@archlinux.org>
