original ec_encode_bin()/ec_decode_bin() to optimize performance when ft is
a power of two.

Making it so all the information encoded directly with ec_enc_bits() gets
stored at the end of the stream, without going through the range coder. This
should be both faster and reduce the effects of bit errors.

Instead of trying to maximize the number of trailing zeros (minimize the number
 of bits encoded), we try to maximize the number of trailing bits that can
 contain arbitrary data.
Note that this requires ec_enc_tell() and ec_dec_tell() to reserve an extra
 bit, since depending on the exact final codeword, as little as half the final
 range might be available for storing arbitrary data.
This is the first step needed to start packing literal bits outside the range
 coder (for speed and robustness purposes).

This patch makes it safe to call the encode / decode functions with a NULL pointer in place of the pcm buffer.
