This change (in a new config experiment: universal_hp) removes the
bitstream parsing dependency of the HP MV bit on the ref MV to be
coded. It also cleans up clearing of the HP bit in near/nearestMV,
since HP is always on if it's set in the frame header.
This admittedly doesn't clean up the crap that could be cleaned up,
but that's mostly because I think this needs some careful review;
not so much for coding style, but more from hardware people and from
the codec team on what we/you want. It would also be nice to get some
actual numbers on the real quality impact of this change. If, for
example, hardware people come up and tell us they don't actually care
anymore, we should probably just this code as-is and do nothing (i.e.
discard this patch).
See issue 1036.

The obj_int_extract code is no longer worth maintaining. It creates
significant issues when adapting for different build systems and no
longer offers as significant of a performance benefit due to
improvements in intrinsics.
Source files will remain until the various third-party builds are updated.
The neon fast quantizer has been moved to intrinsics. The armv6 version
has been removed because so few remaining targets require it.
Compilers and processors have improved significantly since the
pack_tokens code was written. The assembly is no longer faster than the
C code.
pack_tokens were the only optimizations for the armv5te targets so the targets
will be removed after the test infrastructure has been updated.

Incorporates the WRAPLOW macro into the non-highbitdepth transforms
to aid hardware verification between a software C model and an
intended hardware implementation though the use of the configure
options: --enable-experimental --enable-emulate-hardware.
Note that to avoid further discrepancies between the sse/sse2
implementations of the transforms and the C implementation, when the
emulate hardware option is invoked, we also disable sse/sse2/etc.
Also incudes some minor cleanups/renaming etc.

Adds various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

This commit adds a configure time option used to enable strict error
checking in decoder to make sure intermediate stage cofficients of
inverse transforms are within valid range of signed 16 bit integer.
For valid VP9 input streams, intermediate stage coefficients should
always stay within the range of a signed 16 bit integer. Coefficients
can go out of this range for invalid/corrupt VP9 streams. However,
strictly checking this range for every intermediate coefficient can
be a burden for decoder, therefore such validation is only enabled
with configure option --enable-coefficient-range-checking.

This version of the loop filter supports non-4:2:0 subsampling and
a fourth plane, as well as changing the filtering order to be more
friendly to hardware implementations.
The filters are applied first to all vertical edges within the
64x64 SB, followed by the top horizontal edge and any internal
horizontal edges. Since filtering is applied on each 4x4 edge
serially, a dependency is created from filtering one block edge
to the next. It would be possible to remove this depencnecy by
building all filtering decisions from the unfiltered
reconstruction data.

This patch changes the coefficient tree to move the EOB to below
the ZERO node in order to save number of bool decodes.
The advantages of moving EOB one step down as opposed to two steps down
in the other parallel patch are: 1. The coef modeling based on
the One-node becomes independent of the tree structure above it, and
2. Fewer conext/counter increases are needed.
The drawback is that the potential savings in bool decodes will be
less, but assuming that 0s are much more predominant than 1's the
potential savings is still likely to be substantial.
