The various tap loop filter operations are common functions across
codec. This commit moves them along with SIMD optimizations to
vpx_dsp folder.

Move the clamp functions to vpx_dsp_common.h file. Clear out the
dependency of vp9_loopfilter_filters.c on vp9_common.h file.

This commit simplifies the intra block boundary condition logic.
It removes the block index from the argument set.

The encoder gets its dqcoeff from the context tree. In the decoder move
it to directly after MACROBLOCKD.

The decoding process handles detokenization and reconstruction per
transform block sequentially. There is no need to offset the dqcoeff
buffer according to the transform block index. This allows to
reduce the memory spill and improve cache performance.

inline the code directly in read_mv_component(), the only place where it
was being used; this removes a function call in a hot function

This reverts commit a42df86c035d1bc007dbc816b4b758605135d6d9.

The vp9_lpf_vertical_16_dual function optimized for x86 32bit target. The hot code in that function was caused by the call to the transpose8x16.
The gcc generated assembly created uneeded fills and spills to the stack. By interleaving 2 loads and unpack instructions, in addition to hoisting the consumer
instruction closer to the producer instructions, we eliminated most of the fills and spills and improve the function-level performance by 17%.
credit for writing the function as well as finding the root cause goes to Erik Niemeyer (erik.a.niemeyer@intel.com)

This commit moves the primitive multi-threading files from vp9
folder to vpx_thread, which will be accessible by all vpx codec.
