This reverts commit a82001b1cf, reversing
changes made to f6d870f7ae.
This commit breaks windows builds and needs some work to fix those and
some additional comments.

We used set_partition_seg_context() only before calls to:
1. update_partition_context()
2. partition_plane_context()
Moving these functions from vp9_blockd.h to vp9_onyxc_int.h and
inlining set_partition_seg_context into them. After that it is not
necessary to have {above, left}_seg_context fields in MACROBLOCKD struture,
so removing them also.

replace VP9D_COMP usage with the (slightly) more targeted
VP9_COMMON/MACROBLCKD/struct segmentation structures.

This 2-pass rate control setting allocates bits based
on first pass stats to each kf group, gf group and individual
frame but does not correct the bits left and allocation after
each frame.
In other words it recommends a bit allocation for each frame
but does not try and correct any over or under spend on a
frame over the remainder of the clip. This reduces the accuracy
of rate control in terms of hitting an average bitrate but prevents
problems that may arise because early frames either use to many
or too few bits. This mode is currently more inclined to undershoot
than overshoot (particularly at higher data rates).
Also minor changes to rate of adaption when recode loop is not
enabled.
This mode is currently enabled by default for VBR.
It gives the following % performance gains.
derf +0.467, +1.072
yt 2.962, 2.645
stdhd 1.682, 1.595,
yt-hd 2.3, 2.174

Delta reduced because of concern about popping on some
very hard clips.
Also allow some frame recode at speed 2 for kf/gf/arf.

This patch fixed a bug that caused 32bit PIC build mismatch. The
stack pointer was modified after "GET_GOT". Loading left pointer
from a hard-coded position gave wrong result.

Commit "d207 intra prediction ssse3 using bytes" caused mismatch
while building 32bit PIC code. Disabled these SSSE3 functions
until we fix the bug.

This commit makes the buffer allocation of zcoeff_blk array in
pick_mode_context block size aware. It calculates the number of
4x4 blocks in the partition and assigns the memory space accordingly.
This process (and the uninitialization) is done once for each encoding
pass. It allows memory copy of smaller buffer when possible.
For football at 600kbps, the runtimes improve by about 1%:
speed 1, 45961ms -> 45472ms
speed 2, 23863ms -> 23598ms

in most cases at least the left column was a harmless race as it was
left unused later in the code.

Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.

That makes decoder and encoder (only bitstream writing part) a little bit
simpler and faster. Moving get_sb_index() function to the encoder.

coef_counts is now in cpi->mb, instead of cpi. The commit corrected the
mis-use and enable succefual build.

Making this change in order to move allow_high_precision_mv field
from MACROBLOCKD structure to VP9_COMMON (because it is a frame level
flag).
