Introduce xbps_{array,pkgdb}_foreach_cb_multi() and use it where appropiate.

In some tasks the single threaded implementation outperms the multithreaded
one. Use it where it really makes a difference. The _multi() routines do not
spawn any thread if _SC_NPROCESSORS_ONLN == 1.

Bump XBPS_API_VERSION.
