When CONFIG_POSTPROC is set there was a now
invalid reference to cm->filter_level.

Changed to cpi->mb.e_mbd.lf.filter_level in line with
change Iaf5fb71c33719cdfa1b991f671caf071be9ea035

At speed 2, due to the threshold scheme used, it is possible the rate
and distortion assigned with INT_MAX value. The patch added checking
to prevent the INT_MAX value is used in further calculation of RD
scores. The patch also changed the assertion in rd_use_partition() to
be mirror similar assertion in rd_pick_partition().

Using cm->frame_contexts[cm->frame_context_idx] as source of previous
probabilities.

Adding loopfilter struct with fields from MACROBLOCKD and VP9Common.
Eventually it will be moved to vp9_loopfilter.h for better code structure.

Removed arrays: kf_boost_seperation_adjustment,
                gf_adjust_table,
                gf_intra_usage_adjustment,
                gf_interval_table.

Changing fc->tx_probs back to fc->pre_tx_probs. This change actually
affects the bitstream but current test vectors work. Chrome branch is not
affected at all. Broken since:

cc662dd7 Adding struct tx_probs and struct tx_counts to cleanup the code.

Moving TX_MODE enum to vp9_enums.h. Renaming txfm_mode variables to
tx_mode.

We would skip the rectangular blocks for sub8x8 partitions because
we would conclude that PARTITION_NONE was better than PARTITION_SPLIT,
however, that conclusion was made before we actually really tested
PARTITION_SPLIT.
