[pacman-dev] duplicated ldconfig after -S

Hi! We fixed the bug that -U doesn't run ldconfig, but now in case of -S ldconfig runs twice, because -S induces and upgrade transaction too. So _alpm_ldconfig can be removed from _alpm_sync_commit. Anyway, I don't like this "pseudo-transaction" way, at least we should use different transaction types (see my PM_TRANS_TYPE_UPGRADERM patch). I think some depcheck codes should be moved to deps.c from sync.c. Bye, ngaba
