The function is called only once, right after all stats counters are
reset to 0. Therefore all the computations have zero effect on return
values. This commmit to removed those effectless code.

Reinstates an assignment to prevent an asan failurere on google3.

At speed 6 the smallest partitioning was 16x16 and biggest
intra block was 8x8, essentially disallowing all intra blocks
which produces ugly artifacts when revealing new video.

Reverts to using tmpfile() for non-Windows platforms. On google3
the test directory does not have write permissions, and hence the
Y4mWriteTest fails. This patch fixes the issue.
On Windows, a temporary file is created in the temp directory
that has write permissions.

The tests pass on linux, mingw, and MS visual studio.

When a valid data pointer is given make sure the size is greater than
zero.
A previous check for vp9 was incorrectly removed in:
70500747 Make the api behavior conform to api spec.

No semantics for valid pointers + 0-sized frames are defined for VPx
codecs, so move the check to vpx_codec_decode(). This avoids an assert
in vp9.

+ add some basic invalid param testing for decoder init/decode/destroy
