bit-exact with original version

Should gives us ARM/SSE optimizations for free.

This prevented opening the files from the 'Solution Explorer'
interface where the source listing is displayed. Thanks to
Koen Vos for reporting the issue.

Thanks to thinqa for the report.
Fixes #1968.

By default Visual Studio warns about various C stdlib calls,
recommending non-portable replacements instead. We disable
this warning in a number of places in the source.

Since they're specific to the Visual Studio build, it's better
to disable them just in the project files where they always
apply to the correct toolchain.

I have only added the disable setting to project files which
need it currently: opus, test_opus_encode, and test_opus_decode.

This warning disable was conditional on _WIN32, which mingw
also defines, resulting in a warning about the unknown pragma
on gcc. Instead make it depend on something only the Visual
Studio compiler defines.

This reverts commit 43279728.

This reverts commit 715b37f6.

At a minimum MSVC warns on some of this stuff.

This avoids at least one case where ./autogen.sh && ./configure && make
will re-run configure because the makefile rules updated something that
it depends upon. Pulling a new version from git will change the version
so we should update that at the first step rather than iterating after
the last one.

More conservative surround masking
Disables temporal VBR on surround
Disables tonality on LFE

Centre channel now contributes sqrt(.5) to both channels
Reduces the stream offset at low bitrate

Applies temporal VBR up to higher bitrates after IgorC reported it being
useful at 64 kb/s for amount=0.1

It only existed to not include -lm in the .pc for fixed point builds,
but that is still needed since the float API is still enabled and
will use at least lrint.

Also makes the CTL bad argument handling more consistent to avoid mistakes
 like that in the future.  Also updates the variable duration docs.

Automake 1.13 complains that INCLUDES is obsoleted now.
