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

add system for verifying that encoded frame size estimates are accurate; clean up the code for rice parameter searching and rice codeword length estimation
