Introduce struct xbps_handle and use it for xbps_init().

Browse Source 
This structure sets up function callbacks for fetching files and
unpacking binary packages, as well as setting the debug boolean.

This way the affected functions (xbps_fetch_file() and
xbps_unpack_binary_pkg()) do not need to accept the fn cb pointers
and data as arguments.

Bump XBPS_RELVER.
