Encoder/Decoder mismatch fix: need a separate copy of eob_counts.
The bug was introduced here:
https://chromium-review.googlesource.com/#/c/399975/4/av1/encoder/bitstream.c

name. But it turns out that the two variables actually had a different
type (even though the name was same).
Now, we keep both variables, but rename one of them -- that fixes the
mismatch. While we are at it, made both variables local as well.

We need to re-develop the column txfm side scaling/rounding. Now,
we prefer to maintain the current BDRate level.
- Encoder user level time reduction <1% owing to av1_fht32x32_avx2.
- Add MemCheck unit test and fdct32() unit test.

Fix for AV1.TestTell
The tell functions return an unsigned integer.
This causes the AV1.TestTell test case to fail because
-1 is greater than 20 when treated as an unsigned integer.
