Still more changes to come

C reserves identifiers of the from _[A-Z]+ and we have a number of
those in the code. This patch renames the various function arguments,
MACROS and preprocessor symbols to avoid the reserved form.

It also removes the CHANNELS() macro altogether. This was a
minor optimization for TI DSP to force a mono-only build,
as were the associated local 'const' versions. Since stereo
support is manditory, it wasn't worth keeping.

Thanks to John Ridges for raising the issue, and Jean-Marc Valin
and Greg Maxwell for reviewing the changes.

We use macros to encapsulate the appropriate type and size
information for the different CTL requests, but the macros
still need to be used with the _ctl() function call and an
encoder or decoder instance structure. As such, just listing
the macro defines is confusing. Adding some examples outside
the OpusEncoder overview page should help with this.

Also document that OPUS_SET_APPLICATION can take
OPUS_APPLICATION_RESTRICTED_LOWDELAY.

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