Simplified idct32x32 calculation when there are only 10 or less
non-zero coefficients in 32x32 block. This helps the decoder
performance.

* changes:
  Ignoring test video sequences in the source tree.
  Code cleanup.

gf_group_bits is int64_t remove casts to int.

Change-Id: I3b4225905041fac9af9fdfcbcb6f1c357ea4b593

Adding /*.ivf and /*.ivf.md5 filename patterns to .gitignore.

Change-Id: I9be9c99023e6b59bcc9cfbb6c9d6cdc8e500fc4f

Lower case variable names, converting while loops to for loops.

Change-Id: Ic3b973391eef7472a99d18d02fe79cfef5e04e62

Provided a wrapper and removed duplicate code.

The ABOVESPREFMV experiment uses four pixels to the left of the
current block, which don't exist for the left-most column.

Change-Id: I4cf0b42ae8f54c0b3e7b1ed8755704b74fafc39c

Removing redundant variables, using x *= y instead x = x * y, moving
variable declarations into inner blocks.

Change-Id: I884f95c755f55d51b7c1c6585f10296919063e41

Removing redundant 'extern' keyword, better formatting, code
simplification.

The width and height stored in the reference frames are padded out to
a multiple of 16. The Width and Height variables in common are the
displayed size, which may be smaller. The incorrect comparison was
causing scaling related code to be called when it shouldn't have
been. A notable case where this happens is 1080p, since 1088 != 1080.

sse4_1 code used uint16_t for returning sad, but that
won't work for 32x32 or 64x64.   This code fixes the
assembly for those and also reenables sse4_1 on linux

Scalar path is about 1.4x faster (4% overall encoder speedup).
SSE2 path is about 7x faster (13% overall encoder speedup).

Change-Id: I7e85d8225a914a74c61ea370210414696560094d

Fixing code style, using array lookup instead of switch statements for
forward hybrid transforms (in the same way as for their inverses).
Consistent usage of ROUND_POWER_OF_TWO macro in appropriate places.

* changes:
  convolve test: validate 1D filters are 1D
  Run all filters through convolve test

Fixes a rollover of the cx_time variable for encodes that take
over ~4200 seconds. Also enable the time estimate in first pass.

Change-Id: Ib5a98ee71bccd79a804d709cec7260651d0b7141

Fixing indentation, removing redundant parenthesis, deciphering single
letter variable names, better spacing.
