This makes several small adjustments to our exposed method names, and in
one case, parameters. The justification here is to make methods less odd
in their naming convention. If a method takes an alpm_db_t argument, the
method should be named 'alpm_db_*', but perhaps more importantly, if it
doesn't take a database as the first parameter, it should not.
Summary of changes:
alpm_db_register_sync -> alpm_register_syncdb
alpm_db_unregister_all -> alpm_unregister_all_syncdbs
alpm_option_get_localdb -> aplpm_get_localdb
alpm_option_get_syncdbs -> aplpm_get_syncdbs
alpm_db_readgroup -> alpm_db_get_group
alpm_db_set_pkgreason -> alpm_pkg_set_reason
All methods keep the same argument list except for alpm_pkg_set_reason;
there we drop the 'handle' argument as it can be retrieved from the
passed in package object.
