This array is only used by the malloc failure test, and
defining it unconditionally creates an unused variable
warning on platforms where MALLOC_FAIL isn't set.

This test only works on glibc, but the important thing is support
for the __malloc_hook api, so that's what we should depend on,
especially since not all glibc versions have it.

These pragmas were adding in 4.6, and earlier versions warn
about them being undefined.

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.

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.

Fixes a bug in ec_enc_done when no range coded data was coded and adds test cases to test_unit_entropy.

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.

This avoids potential alignment issues with allocating a char
array on the stack.

Let's put it back in if/when we have a clearer view of voice/music detection

Build tests in the tests/ directory instead of top, cleanup, rename,
and eliminate recursive make for the celt/ unit tests.

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

Renames test_opus to opus_demo and adds the test_opus_api, test_opus_encode, test_opus_decode test programs.

Making SILK bandwidth changes non-normative when there's no redundancy

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.

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.
