Should fix B_PRED-related encoder/decoder mismatches.

Change-Id: I16f808dffd19094e02e8562ba58cc1016155ce93

This fixes edge extension if SB [0,1] doesn't use B_PRED but [1,1] does.

Stray CONFIG_HYBRIDTRANSFORM caused decode mismatch.

Refactor per-transform copy & paste into a common function
update_coef_probs_common() and read_coef_probs_common(). The dry-run and
bit-writing loops in the encoder are still obvious candidates to be made
common, but they start to diverge a bit in the next commit, so are left
as-is for now.

On Ubuntu 12.04, we got the following warning message:
<command-line>:0:0: warning: "_FORTIFY_SOURCE" redefined
 [enabled by default]
<built-in>:0:0: note: this is the location of the previous definition

This was already fixed in VP8 configure file. Did the same change in
experimental branch to stop this warning.

There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
this should be SWITCHABLE but that would make the encoder quite a bit slower.
We will change the default filter to SWITCHABLE once we find a faster way to
search for switchable filters.

The previous double if and else code snippets were rather confusing.

* changes:
  Fix another typo in 4x4-transform-for-i8x8-intra-pred coeff contexts.
  8x8 transform support in splitmv.
  Use SPLITMV_PARTITIONING instead of a plain integer type.

For splitmv, where partitioning is 8x16, 16x8 or 8x8, this patch
uses the 8x8 transform (instead of the 4x4) if txfm_mode is
ALLOW_8X8 or ALLOW_16X16. For TX_MODE_SELECT, splitmv can indicate
which of the 2 transform sizes (4x4 or 8x8) it wants to use.

Gains (with hybridtx4x4/8x8/16x16 and tx_select experiments
enabled) on derf: +0.9%, HD: +0.4%, STD/HD: +0.8% (SSIM or overall
PSNR, both metrics show similar improvements).

This can be used to distinguish between 16x8, 8x16, 8x8 and 4x4
partitioning modes when choosing splitmv as a MB mode.

It currently counts the probability that the branch is true, but it
should count the probability that the branch is false.
