Previously we defined the release version string in configure.ac,
and overrode that with 'git describe --tags' if possible. This
made it difficult for non-autoconf builds to set their version
string correctly.

Instead we create, and check into version control, a file called
version.mk which defines OPUS_VERSION. The configure script reads
that file and uses it as a fallback if the git revision isn't available.

The expectation is that version.mk will be manually updated for
releases, just as the previous configure.ac version was. However,
since this is a simpler format, it is easier for alternate build
systems to use, reducing the number of places which must be updated.

Also removes the OPUS_MINOR_VERSION, etc. defines from config.h.

Updated Win32 genversion.bat to generate version.mk if Git is found, use it if it isn't, and produce unknown version and leave it untouched if it isn't already found

In particular we no longer document the default complexity because
we're not guaranteeing to keep the default value constant.  In the
future the default may be lowered in order to keep the default
speed constant.

We were installing every readable file in man/man3, but
only unstalling files matching opus_*.3. Some doxygen
versions construct manpage versions of the marked up
header files and directory index, which got left on the
system after 'make uninstall'.

I don't think the 'uninstall' target is widely used, it's
often broken and can easily break other software. However,
we rely on 'make distcheck' which does verify this issue.

Instead, only install the opus_*.3 manpages, which are the
core api documentation.

In addition to general reformatting and cleanup, this fixes a
 couple of important mistakes:
- The arguments to OPUS_SET_FORCE_CHANNELS are now 1 and 2, not 0
   and 1 (as they were when this was called OPUS_SET_FORCE_MONO).
- The default encoder mode is now constrained VBR, not unconstrained
   VBR.
It also documents defaults for all the other parameters.

Match up the exit behavior when the no-fuzz enviroment variable
is set.

This implements an API used in future encoders to avoid dynalloc doing silly things
on periodic LSB patterns and to reduce the bitrate on near-silence.

Use exact integer operations to confirm the value returned is the
 correct one.

silk_get_TOC is unused, unreachable, and not useful without some
packet pre-processing, but until we remove it it should be correct.
This was also reported by Mozilla.

The usage of restrict in include/opus_custom.h was missed
by the prior commit replacing this keyword with a macro.

Also fixes some prototype/function agreement with respect to
restrict.

Add more MSVC files to .gitignore.
Make all configurations use default floating point model.

We had previously advised people to -Drestrict on
non-C99 compilers, but this creates problems for
some of the MSVC headers. Instead this just
uses a macro and defines it sanely.

When libopus is forced to sufficiently low rates it will start
outputting 'PLC' (one byte) frames. The code that did this
did not sanitize the mode well enough and would create corrupted
TOC values in some cases.

Thanks to Fatbag for pointing out the issue.

He's an author now.

Plural works better with the previous sentence. The agreement problem
was there in my original commit. I was just confused by the half
that Tim promoted.

Also make the 64-bit builds use the default output directories.
Fix the type of the default Opus output to be a library.

The (non-default) temporary & output dirs configured in the projects could
cause issues when doing compilation on a multiprocessor machine. Cleaned
this up a little to use the defaults, which makes that work again and
doesn't make the output structure any worse. Also removed debug output for
release binaries & a tiny whitespace fix.

Sort alphabetically, and move vorbis-trim to "Informative".
Also fix a misuse of "streams" instead of "channels" in the packet
 size limits exposition.

* Bump the document date.
* Mandate that the ID header must complete on the first page (to
   remove any ambiguities about this requirement in RFC 3533).
* Remove reundant wording that rillian forgot to remove in 360a4117.
* Split the "Granule Position" section into subsections.
* Move the first paragraph of the "Other Implementation Notes"
   section into the "Granule Position" section, add general seeking
   implementation guidance, and be specific about the interaction
   between pre-roll and pre-skip.
* Retitle the remaining contents of the "Other Implementation Notes"
   section to "Packet Size Limits"
* Specify that all the header fields are REQUIRED (and add a
   description of the Channel Mapping Table as a whole, so we can
   say when it is REQUIRED).
* Specify that implementations MUST NOT reject headers with extra
   data if they have an unknown minor version number.
* Add a reference to RFC 3629 (UTF-8).
* Minor formatting adjustments to vorbis-trim and vorbis-mapping
   cites.
* Eliminate semicolons and terrible "Else, if" constructs.
