1. Only for fixed point on x86 platform (32bit and 64bit, uses SIMD
   intrinsics up to SSE4.2)
2. Use "configure --enable-fixed-point --enable-intrinsics" to enable
   optimization, default is disabled.
3. Official test cases are verified and passed.

Yusuke Nakamura's draft for opus in the ISO Base Media File Format.

Considers the case where one stream would eat up all the remaining bytes,
including a 2-byte size that would then not leave enough for the even a PLC
packet in the next streams.

Limit now at 2*streams-1 and anything below that returns OPUS_BUFFER_TOO_SMALL
rather than OPUS_BAD_ARG

These are normative whether capitalized or not. Capitalize the ones
which make sense as normative requirements, and reword the rest.

We want to general guidelines for stream-level encapsulation to
apply to multiplexed as well as degenerate streams. 'Files' can
therefore specific to the mine-type discussion for unmultiplexed
Ogg physical streams.

These are the changes proposed in
 <http://www.ietf.org/mail-archive/web/codec/current/msg03058.html>,
 with some minor additions (see follow-up on the list).

Promote the new tag definitions to a separate subsection,
balance tags, improve wording, and document our motivation
for the R128 tags.

Thanks to Calvin Walton for pointing this out.

This is the result of an editing pass for clarity and consistency.

genversion.bat would fail if an argument was passed with quotations.
This is because the quotations were not being stripped before using
them as variables, causing the _temp files not being created.

Adding ~ to the arguments causes windows to strip the quotations,
enabling it to be used with path names containing spaces and the
MSVS pre-build event.

Addresses comments from several months ago

OPUS_AUTO should now work fine, while using OPUS_BITRATE_MAX would still
be a bad idea for controlling CBR rate for multistream. The encoder should
now throw an error early on if max_data_bytes is just too small to do anything.

- Bug fix: the CNG synthesis filter output consisted of only the prediction
  values, now added the input to that.
- CNG excitation level now takes into account the level from the PLC (since
  both PLC and CNG can be active at the same time).
- CNG is now called before PLC_glue() to smoothen the transition out of CNG.
