Add public methods SplitUVPlanes and MergeUVPlanes based on the

The conversion from NV12 and other Bi or Tri planar formats, differs only in the UV handling.  The helper function supports passing a NULL for the dst_y channel indicating you only want to do the UV conversion.

Add a lot of new dependencies for the Android toolchain
to setup_links.py (added for WebRTC in https://codereview.webrtc.org/2190893002
and https://codereview.webrtc.org/2215633002).

There was no other way to get the Android test to build
than renaming the APK to yuv_unittests. That made it possible
to use build/apk_test.gypi (there's some bug somewhere that assumes
names doesn't start with "lib", see http://crbug.com/543820).

Work around for android full debug build runnign out of registers.
5 functions were running out of registers causing the compiler error
error: 'asm' operand has impossible constraints
These functions mostly have 4 pointers, a counter (width) and a tempory
eax register.  With fpic and debug using stackframes, 2 registers are
unavailable.  So a total of 8 registers are used.
Although fpic and stack frame dont apply to assembly, the compiler
reserves 2 registers.  The optimized version builds, so its likely
freeing up the registers once it knows they are not used.
These functions used to build, so compile options and/or compiler may
have updated.. likely fpic was turned on.
An attribute can be done to disable each, and will avoid using the
2 GPR registers, but they are still reserved and unavailable in debug
builds on current compilers (gcc 4.9 and clang 3.8).
