b88a7baf34 Use #pragma GCC diagnostic push/pop only on gcc 4.6 and later. 
These pragmas were adding in 4.6, and earlier versions warn
about them being undefined.

c19bc34638 Check for __malloc_hook and define MALLOC_FAIL appropriately. 
The glibc 2.14 NEWS file says __malloc_hook will be removed
in the next release, so future-proof our use by checking
for this symbol at configure time and only compiling the
malloc failure tests if it is present.

ed90cdc369 Disable the deprecated function warning on __malloc_hook. 
This just works around the deprecation in glibc 2.14. I
do worry what will happen if they follow through and
remove it in 2.15.

16abc6fe6e Fix for ec_enc_patch_initial_bits(). 
The test to make sure that _nbits had been encoded was checking for
 8-_nbits instead of _nbits.
This only affected cases when less than 8 bits had ever been
 encoded by the time the initial bits were patched.

c8649d0e0b Gives the Opus code direct access to (non-opaque) OpusRepacketizer 
This avoids potential alignment issues with allocating a char
array on the stack.

Also reformat some, but by no means all, of the opus
code for line length and three-character indents.

ec1ebf8ad7 Fixes a bug on FEC+stereo 
When FEC is enabled in the decoder but not included in the bit-stream
we could end up applying the PLC on a non-existant side.

a7585a0dd1 More draft edits and additions. 
Some clean-up from JM's prior edits, as well as
* Additional clarificatino of TOC sequence restrictions (e.g., if
   you need to decode a length, there must be enough bytes in the
   packet for it, etc.).
* Added a summary of TOC sequence restrictions.
* Added a stereo unmixing section.
* Reworked Delay Compensation section into a general Resampling
   section.
* Further cleanups of switching/transitions, including new diagrams
   for all of the normative and recommended non-normative
   transitions.

3b2aee062d Implements glitchless switching between SILK bandwidths 
Only encoder changes were necessary because this uses the same
"redundant frames" mechanism as SILK<->CELT switching.
This also fixes a regression introduced in 78291b27 that was
causing the encoder to go back and forth between bandwidths when
SILK wasn't ready to change.

294bfec27b Implements hard CBR for SILK 
This is achieved by running the encoding process in a loop and
padding when we don't reach the exact rate. It also implements
VBR-with-cap, which means we no longer need to artificially decrease
the SILK bandwidth when it's close to the cap.
