add --warnings-as-errors option to flac; for picture importing, allow MIME type in specification to be blank and filled in automatically; allow specification to be just the filename, with other fields filled in automatically

for --import-picture-from, allow MIME type in specification to be blank and filled in automatically; allow specification to be just the filename, with other fields filled in automatically

allow MIME type in specification to be blank and filled in automatically; allow specification to be just the filename, with other fields filled in automatically

fix bug where specifying --picture in FLAC-to-FLAC transcoding did not have any effect (SF#1627993: http://sourceforge.net/tracker/index.php?func=detail&aid=1627993&group_id=13478&atid=113478)

in FLAC__stream_encoder_set_metadata(), copy the metadata array of pointers instead of requiring the caller to keep it until initialization; the objects themselves are still owned by caller

several speed improvements: completely rewritten bitbuffer which uses native machine word size instead of bytes; much faster rice partition size estimation; crc16 calculation in machine word size
