799e232490 flacdsp: move lpc encoding from FLAC encoder to FLACDSPContext
Also, templatize the functions for 16-bit and 32-bit sample range. This will
be used for 24-bit FLAC encoding.

6a744d2619 flacenc: use a separate buffer for byte-swapping for MD5 checksum on big-endian
This is much faster than calculating the MD5 one sample at a time.
