Change the internal lib targets so that external apps
need link only libaom instead of all internal library
targets and libaom.

This is enabled via:
$ cmake path/to/aom -DBUILD_SHARED_LIBS=1
Currently supports only Linux and MacOS targets. Symbol visibility
is handled by exports.cmake and its helpers exports_sources.cmake
and generate_exports.cmake.
Some sweeping changes were required to properly support shared libs
and control symbol visibility:
- Object libraries are always linked privately into static
libraries.
- Static libraries are always linked privately into eachother
in the many cases where the CMake build merges multiple library
targets.
- aom_dsp.cmake now links all its targets into the aom_dsp static
library target, and privately links aom_dsp into the aom target.
- av1.cmake now links all its targets into the aom_av1 static library
target, and privately links in aom_dsp and aom_scale as well. It
then privately links aom_av1 into the aom target.
- The aom_mem, aom_ports, aom_scale, and aom_util targets are now
static libs that are privately linked into the aom target.
- In CMakeLists.txt libyuv and libwebm are now privately linked into
app targets.
- The ASM and intrinsic library functions in aom_optimization.cmake
now both require a dependent target argument. This facilitates the
changes noted above regarding new privately linked static library
targets for ASM and intrinsics sources.

Requires use of new cmake toolchain file:
$ cmake path/to/aom -DCMAKE_TOOLCHAIN_FILE=path/to/aom/build/cmake/toolchains/mips32-linux-gcc.cmake
DSPR2 and MSA are supported via addition of -DENABLE_DSPR2=1 and
-DENABLE_MSA=1 respectively. Note that the latter requires the addition
of -DMIPS_CPU=p5600.

A similar cleanup happened before, but the empty statements have since
reappeared. I added a check in 'specialize' subroutine to die whenever
such an empty specialize call is found, so that config+make would fail.

Enables Wiener based loop restoration only for the UV
frames. The selfguided and domaintranform filters do not
work very well for UV components, hence they are disabled.
For each UV frame a single set of wiener parameters are
sent. They are applied tile-wise, but all tiles use the
same parameters.
BDRATE (Global PSNR) results:
-----------------------------
lowres: -1.266% (up from -0.666%, good improvement)
midres: -1.815% (up from -1.792%, tiny improvement)
Tiling on UV components will be explored subsequently.

The global motion detection only works on 8-bit buffers,
so any frames using 16-bit buffers are now down-converted
to 8 bits when necessary.

This avoids explicitly casting them to 'int' later.
These methods were already called with signed int arguments for pitch,
so this also avoids int -> unsigned int -> int conversion.

For example, loops of the form:
"for (i = 0; i < 1 + max_value; ++i) ..." or
"for (i = 0; i <= max_value; ++i) ..." are possibly infinite loops,
theoretically speaking (even if practically, they aren't).
So, compiler cannot optimize those loops.
When possible, I rewrote such loops to be finite even theoretically.
