Including a description of the PVQ encoder and decoder

See http://www.ietf.org/mail-archive/web/codec/current/msg02833.html
Still more changes to come

- Draft updates
- Updated code to produce and check test vectors
- Making sure that the test vectors pass at all rates as well as for mono and stereo

- Safer gain clamping for PLC
- Makes opus_decoder_get_nb_samples() report an error on invalid ToC
- Giving a free license to the text ofthe draft (not just the code)

The range decoder used to initialize nbits_total after the
 renormalization loop, even though the renormalization loop
 modifies it.
This was presumably safe, because nothing actually used the value
 before it was initialized, but I'm tired of it triggering the
 integer overflow checking.

Also regularises some Canadian spelling to US like the rest of
the document.

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

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.
