e610864c74 This fixes a VBR bug introduced by raw bits. We should not write any raw 
bit before the rate is decided (otherwise they'll end up at the wrong place)
and we have to shrink the byte buffer before writing raw bits.

949a29bf0c Raw bits encoding/decoding functions renamed to *_raw() and re-introducing 
original ec_encode_bin()/ec_decode_bin() to optimize performance when ft is
a power of two.

c08be4485b Implemented "raw bits" 
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.

0268a99676 Fix ectest to not check a case which isn't guaranteed to work, and which we don't use. 
When I removed the special case for EC_ILOG(0) in commit
 06390d082d, it broke ec_dec_uint() with _ft=1
 (which should encode the value 0 using 0 bits).
This feature was tested by ectest.c, but not actually used by libcelt.
An assert has been added to ec_dec_uint() to ensure that we don't try to use
 this feature by accident.
ec_enc_uint() was actually correct, but support for this feature has been
 removed and the assert put in its place.

c2decd39a6 Made a second version of ec_{en|de}code optimised for encoding bits (no div 
required) and using it in ec_{en|de}c_bits()

dc767f67f9 No longer trying to save bits when encoding integers near the upper limit 
(and fix for celt_div with 16-bit numerator on a 16-bit CPU)

6238bc0ece Moved the content of libentcode into libcelt to reduce dependencies, 
especially now that we have a custom version of that code anyway. Moved
the test code to tests/

Renamed from libentcode/entenc.c (Browse further)
