2fecbdf084 Fixed the default int32 type which was wrong on amd64 (and added testcase). 
Also, added an Ogg encoder (doesn't work quite yet).

(need to have test files installed otherwise it'll just pass by default)

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

7e3293f713 Fix the bug that was causing the last byte of the stream to be returned incorrectly, as well as undo jm's reversion, which can cause ec_dec_tell() to operate incorrectly at the end of the stream. 
A few other minor updates are included as well.

encode function. Also, trying to properly flush the bit packer
(still some problems left).

3eff11d8d4 Add ec_dec_tell() to report the same information as ec_enc_tell() decode side. Remove ec_enc_tell() and replace it with ec_enc_tellf(): just request 0 fractional bits if you want an integer value.

06390d082d Add oc_enc_tell to report an estimate of the number of bits used so far. 
Remove the special case for 0 in EC_ILOG, as we never pass it 0 and this
 generates slightly better code.

Update ec_enc_bits64 to split the encoded values along word boundaries...
 this should generate slightly better code, as well as fix a subtle bug (the
 proper bits were not being masked out of the low part).
However, this will render previous streams that used this function undecodable
 (to my knowledge, no one is actually using it yet).
