"Foo replaces bar" simply means that "foo is a new version of bar".
So this patch refactors the code to use this "rule".
_alpm_sync_sysupgrade now does the following for each local package [bar]
(pseudo-code):
for db in syncdbs {
if(db contains bar) {check if db/bar is an upgrade; break;}
replacers = find(bar replacers in db);
if(replacers!=NULL) {ask_user; break;}
}
Note:
1. Replacers are grouped per repo. If more than one package replace bar in
a repo, all of them are considered ("package set of bar replacers").
2. If repo1/foo1 and repo2/foo2 both replaces bar, only repo1/foo1 is
considered (if repo1 stands before repo2 in pacman.conf). FS#11737 is fixed.
3. It can happen that pacman doesn't consider any replacer, if it found a
literal "earlier", so sync132.py modified accordingly (btw, that situation
should not appear irl).
The new sysupgrade code doesn't use sync_newversion(), so I removed the
"local is newer than repo" message, which was annoying with -Qu and
SyncFirst.
