Dan McGee fb4b422fc4 New signatures for alpm initialize and release
These new method signatures return and take handle objects to operate on
so we can move away from the idea of one global handle in the API. There
is also another important change and that deals with the setting of root
and dbpaths. These are now done at initialization time instead of using
setter methods. This allows the library to operate more safely knowing
that paths won't change underneath it.
