In VS 2015 and higher snprintf is supplied and therefore vsnprintf
doesn't need to be defined. This also avoids problems caused by
_snprintf being different from snprintf.

This fixes a build break with VS 2015 and improves security.

Additionally break this MSVC-specific tweak to a new file, which will
become the home of all such MSVC-specific things.

This requires adding a dependency on msvc.h to every example which uses
args.c and tools_common.h

Increase the 32x32 split threshold, to allow for more 32x32
at expense of 16x16. Visually looks somewhat better.

Break out the setting of the block variance split thresholds,
since they are locally modified, e.g., based on local/segment qp.

No change in performance.

+ synchronize filter function signatures

this makes any intrinsics filters available for inlining and has the
side-effect of making those filters static, quieting missing-prototype
warnings.

This patch addresses two issues that can occur when the
encoder chooses to use a mixture of ARF and GF groups.

The first issue relates to a failure to reset the "ARF active" flag
correctly when transitioning from coding ARF groups to coding
GF groups. This caused some golden frames to be  encoded
with an incorrect bit rate target as if they were ARF overlay frames.

The second issue relates to the encoding of a single short GF group
just before a key frame.  Where the last group before a key frame
is an ARF group we expect the final frame before the key frame  to
be an low data rate overlay frame. However, when the last  group
is a GF group, the final frame before the key frame should be a normal
frame with a normal bit allocation. This issue had the potential to cause
a single poorly coded frame just before a key frame. If that key frame
were a forced key frame rather than a real scene cut, this might cause
pulsing.

This allows rate control to react to content of current frame being encoded.
