To turn on vp10, one needs to explicitly set --enable-vp10.

This commit folks the VP9 and VP10 codebase and makes libvpx

the target, and android and chrome do not use the targets.

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.

Change-Id: I3c56de79e15b904d6f655b62ffae170729befdd8

Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
Also includes most vpx level high bit-depth functions. However
encode/decode in the highbitdepth profiles will not work until
the rest of the code is in place.

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 is a practical concern to allow us to fail in a decoder instance
if the size of a file is bigger than we can reasonably handle.

Add a conditional compile flag for this feature. Also add a
switch to enable the encoder to use these statistics in the
second pass. Currently, the switch is turned off.

Really just armv7. This is a convenience target intended to make iOS
development with libvpx easier. Xcode projects with default settings
will fail to build when a framework lacks armv7s support when targetting
iOS7.
