These are only being used outside if the translation unit and only in
a few codepaths; by making them static in the header, the compiler can
optimize them quickly.

This avoids GOT-based access to the external symbol on Unix, and can
allow for constant propagation to optimize the code.

This is similar to the change for functions, but is only used to
perform DCE.

This allows the compiler to perform more optimization on them as it
knows how the functions are being called.

While this is not making a huge difference it still makes the code
more consistent.

This allows the decoder to be compiled with
 NONTHREADSAFE_PSEUDOSTACK to move the memory for large buffers off
 the stack for devices where it is very limited.
This patch only attempts to do this for the decoder.
The encoder still requires more than 10 kB of stack.

This avoids allocating any buffers on the stack that depend on the
 total channel count.
Such buffers could easily exceed the size of the
 NONTHREADSAFE_PSEUDOSTACK.
It also checks the frame_size argument in both the encoder and
 decoder to avoid allocating large stack buffers for opus_encode()
 calls that would fail anyway or opus_decode() calls that would
 never use all that space anyway.

This makes simple syntax highlighters (e.g., vim) stop complaining
 because they don't parse the #ifdef's.

Instead use cd inside the makefiles.
This fixes 'make check', etc. with some non-gnu makes. (HPUX, for example)

 On some systems (HPPA+HPUX+GCC) -fstatck-protector was causing failures not
at build or link time but at actual runtime. This is much less reasonable to
detect from autotools. It looks this this really can only safely be a white-
list, and the systems which would be whitelisted often already pick up the
setting from the OS build environment in any case.  It isn't important for
OPUS, we were just using it as belt-and-suspenders security and because it
makes some failure types easier to troubleshoot.

Thanks to Andrew D'Addesio for the report.

Further cleanup of the confusion with the version string settings.

I'm not sure how this worked before, the the previous version
string fiddling commit ended up not defining OPUS_VERSION in
the autoconf build, so opus_get_version_string() returned
'unknown'.

Microsoft Visual Studio 2010 warns about 'C4146: unary minus
operator applied to unsigned type, result still unsigned'
because of the '&-sizeof(void*)' in align().

This commit works around the warning by casting the size_t
to int before negation.

Patch by Hauke, who reported the issue on the opus mailing
list. Reviewed by derf.

This is another script generated by the autotools build.

This reduces the number of places the version string
needs to be updated at release.

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.
