_alpm_handle_free: free all in-memory resources

Browse source 
Freeing handle resources was previously split awkwardly between
_alpm_handle_free and alpm_release.  This consolidates the freeing of
all in-memory resources to _alpm_handle_free, leaving alpm_release as a
thin wrapper that provides safety checks and frees any external
resources, e.g. removing lock files.
