Add Bluray support
Unencrypted BD directory trees only. Doesn't support iso images.
Also, no PGS subtitle support yet.
Chapters and angles are supported.
Adds a new contrib libbluray.
Adds new option to hb_scan() for duration of short titles to filter.
This applies to BD and DVD multi-title scans only. Does not apply
to any single title scans.
Fixes memory leak during scan. hb_buffer_close() was not freeing
all buffers in a chain of buffers passed to it.
