pmsyncpkg_t cleanup

Browse Source 
Fix for sync044.py and reason001.py.
Rename sync->data to sync->removes (alpm_list_t *)
Replace pmsynctype_t sync->type by pmpkgreason_t sync->newreason

The type field was set to UPGRADE or DEPEND or REPLACE.
Instead of using type = UPGRADE or DEPEND, we now rather use a
"pmpkgreason_t newreason" field directly (= explicit or depend) which allows
a better handling of the install reason.
And the REPLACE type is now deduced implicitly when the sync->removes list
is not empty.
