Also fixes the "output all zeros" case for DTX/PLC at the beginning of
a stream

and avoid calling rand() during decode in order to make fuzzing
more deterministic.

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.

Updated README files to reflect current output of tool and tweaked punctuation and wording. Corrected typo in test_opus ("constraint"->"constrained").

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).

Saves about 60 bits/sec for 20ms frames.

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.

Repacketizer now seems to work, though it doesn't yet handle
unmergeable packets. Also, test_opis no longer attempt to do proper
gapless at the end of the file, which was causing problems for
repacketization, but also with 32 bit overflows

Still more bugs to find

Thanks to Tim Terriberry for pointing out the issue.

This better distinguishes the reference implementation,
which is what this string is meant to do. Thanks to
Greg Maxwell for the suggestion.

This lets us verify this part of the API is working.

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.

This lets users print it out without context, which is a little
easier for clients.

The new opus_get_version_string() call just returns a static string
defined by OPUS_VERSION, which is passed in from the build system
through config.h (or a custom compile line). Provide a fallback to
"unknown" if the build system fails to actually provide that definition.

This restores compilation with Makefile.draft.

In general, this means there will be builds out there with non-specific
version strings, since ports won't be forced to update the string. While
that's unfortunate, I think it's more valuable that the library be simple
to build.

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.

Fix a warning on gcc 4.6. 'internal_sampling_rate_Hz' was
replaced by 'bandwidth' in a10e8796 but the local variable
holding the setting wasn't removed.

A comment in opus_decode() said, "bit 6 is ignored" when in
fact bit 6 is the padding flag, parsed in the previous block.

The comment, and the previous one, are modified to reflect
the current code.
