The frame mi has an 1 row and 1 column offset from the beginning of
the allocated memory.
cm->mi = cm->mip + cm->mi_stride + 1;
This offset can be removed. This doesn't change the bitstream.

Also, fixed 1 bug in first_pass code to update xd->mi for each block.

(1) We use an initial variable shift, and then
(2) A multiply + 16 bit shift for bit-depth = 8, OR
    A multiply + 17 bit shift for bit-depth = 10 and 12

All the constants (shifts and multipliers) for different block sizes are
based on "Algorithm 1" in
http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=1467632

Note:
This also reverts test hashes etc to the version before
commit 37ebf187.

Under CONFIG_OBU, there are a large number of duplicate lines for the
handling of INTER_FRAME and S_FRAME in the packing of the
uncompressed frame header. Indeed, there are only two lines of
difference between the handling of these two different frame types. By
removing the two lines, it has been confirmed the code between the two
"if" branches are completely identical.

Further, by unifying the handling of these two frame types, the
incorrect handling on S_FRAME under CONFIG_AMVR (default off) is fixed.

Currently set cm->frame_refs_short_signaling as 0 by default. It will
write the one extra bit to the frame header, and leave all the encoder
setup the same as the baseline. It is in the TODO list for the encoder
side implementation for cm->frame_refs_short_signaling == 1.

There are 4 delta_lflevels (FRAME_LF_COUNT=4), corresponding to 2 for the luma
plane and 1 for each of the U and V planes. In monochrome mode we do not need
to use/encode/decode the last two values, and so in this case the for loops all
terminate at FRAME_LF_COUNT - 2 rather than FRAME_LF_COUNT.

This patch simplifies the setting and use of the do_post_rounding
flag consistently across all convolve/warp operations. It is always
set now to 1 for compound modes, but the masked blending operation
can subsequently turn it off.
To accomplish this, for the warped case, the use of the conv_params->dst
buffer is made consistent with the other non-warp convolves,
in the sense that it is used only when is_compound is 1.
