421a628f4d Changing the encoder to output the ToC in DTX mode 
Also fixes the "output all zeros" case for DTX/PLC at the beginning of
a stream

222494f3ea Adds a floating-point API to Opus 
The high-level Opus encoder and decoder can now be compiled as
either fixed or float. Also, we now use the stack_alloc.h macros
in the top-level Opus code.

51ac8e68e6 Fixes a high bit-rate redundant frame bug 
We now ensure that the total payload *including* the redundant frame
is no more than 1275 bytes. Also, the redundant frame itself must
be no more than 257 (the max that can be signalled).

6854556556 Fixes a mode transition bug found by fuzzing 
During SILK->CELT transitions, we were delaying the mode change by
one frame, but only after having ensured that bandwidth and mode were
consistent. We now do the delaying earlier.

641eea83b8 Regularize whitespace in the src directory. 
Remove trailing whitespace, convert tabs to 4 spaces, re-align
test_opus to use 4-space indents instead of 3, and re-wrap some
long lines.

3f0962cc1e Always enable OPUS_TEST_RANGE_CODER_STATE. 
This removes the configurability of the OPUS_TEST_RANGE_CODER_STATE
consistency check, in favour of always running it. The performance
penalty is low, and it's an important check on correctness for the
reference encoder to provide.
