Fix tsan error in VP9 sub8x8 intra mode search
This commit fixes issue 1141. The issue was triggered in multi-tile
encoding. The change properly saves and restores the block context
information in the real-time mode selection process. It removes
several redundant memcpy operations in sub8x8 intra block mode
search.

For the current stage, we assume a single prediction filter type
per direction in the settings of compound inter prediction modes.

Increases number of wedges for smaller block and removes
wedge coding mode for blocks larger than 32x32.
Also adds various other enhancements for subsequent experimentation,
including adding provision for multiple smoothing functions
(though one is used currently), adds a speed feature that decides
the sign for interinter wedges using a fast mechanism, and refactors
wedge representations.

Most of the gain is due to increase in codebook size for 8x8 - 16x16.

The amount of border extension needed in the first stage inter
filtering is decided by the length of the second stage filter
kernel.

- Tx_type: DCT_DCT, DCT_ADST, ADST_DCT, ADST_ADST.
- Encoder overall instruction count drops 2.91%.
- Decoder overall instruction count drops 1.01%.
- Add unit test to test bit-exact result against C.

Avoid accessing transform type that is not 2D-DCT if the transform
size is 64x64. This fixes an assert failure in this unit test.

This commit unifies the inter predictor used in supertx at both
encoder and decoder sides. It removes the redundant decoder
implementations related to border extension.

This commit unifies the inter predictor used in the encoder and
decoder side for super-tx experiment. This resolves an enc/dec
mismatch found in nextgenv2 nightly-run unit test.

Also allows use of --enable-shared when configuring for Mac OS X,
producing a bare .dylib.
Enabling the shared framework bumps the iOS deployment target to 8.0,
the minimum required to support dynamic framework deployment in apps.
When not using --enable-shared, a static library for iOS 6.0+ will still
be built.
Minimum version settings have been moved into ios-version.sh so they
can be updated in a single place.
As with the static build, unless header search paths are manually
tweaked, users must add a VPX prefix on includes, such as:
#include <VPX/vpx/vpx_decoder.h>
A module map for headers is not yet included as inttypes.h is not
modular; this means that VPX cannot be used directly in Swift code,
but can still be pulled in through an Objective-C wrapper.

In the tile-coding experiment,
1. In tile decoder, added 2 set control APIs:
VP10_SET_DECODE_TILE_ROW and VP10_SET_DECODE_TILE_COL. It allowed
users to set the range of decoding at frame level.
2. Added a unit test while tile-coding experiment is on. It tested
both tile encoder and decoder to make sure the encoded frame
can be decoded as a whole frame or as independent tiles.

Fix the variable type mismatch between highbd_calc_masked_var_t and
the actual function definiton. This clears the related compiler
warnings in highbd with ext-inter experiment.
