Call a row function for each row, based on ARGBToI400 code.
But implement row functions as 2 step conversion. Adds the
row functions:
RAWToYJ, RGBToYJ, SSSE3 and AVX2 versions, and Any versions.
The smaller row buffer is more cache friendly on large images.
The max cache size can be configured, and is currently:
// Maximum temporary width for wrappers to process at a time, in pixels.
And the row buffer is
SIMD_ALIGNED(uint8_t row[MAXTWIDTH * 4]);
So 8192 bytes are used for the row buffer, leaving the rest for source
and destination buffers.

The CpuId function is a wrapper for the intrinsic, or
implemented with inline if unavailable. It had been
using uint32, but the intrinsics use int, so it was causing
casting and lint warnings. This change makes the internal
implementation use int.
Casting was also done for xgetbv, and the cast is simply
removed, and is not causing a build error.
MipCpuCaps was doing strlen to check for white space after the
instruction set. Arm also does this but with a hard coded offset.
This was causing a cast from size_t to int, which produced a lint
warning. The change removes the white space detect.
In theory the code could be used to detect SSE vs SSE2, and it would
need to check SSE is followed by a space or end of line. But this
code is only used on Arm and Mips, where there there is one form
of SIMD detected. e.g. MSA for mips. If a new instruction set is
added with a similar name, the write space check could be reintroduced.
But its more likely the code can be rewritten to use a better form
of detection by then. Or remove detection and require the instructions

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).

cpu_info_ is zero for uninitialized state and all bits are off, disabling all cpu optimizations.
the 1 bit indicates cpu_info_ is initialized avoiding calling the detection code again for performance.
MaskCpuFlags initializes the cpu ignoring existing flags, then masks with the supplied flags and stores to cpu_info_.
As a mask, -1 has no effect, enabling all cpu features that were detected, but nothing that wasnt detected.
Setting to 0 will cause the next call to re-initialize the cpu, which is same as enabling all features.
Setting mask to 1 will turn off all cpu features but keep the initialized bit on, so the next detection call wont reinitialize and the cpu features are all disabled.
So normal behavior for command line and programatic masking is:
1 = C
-1 = SIMD

I420ToNV21 passes the wrong dst_stride_y when it calls I420ToNV12; parameter 8 (convert_from.cc:448) is src_stride_y but should be dst_stride_y. This causes image corruption when converting I420 -> NV21 with mismatched luminance strides.

When scaling down by 2 the formula should round consistently.
(a+b+c+d+2)/4
The C version did but the SSE2 version was doing 2 averages.
avg(avg(a,b),avg(c,d))
This change uses a sum, then rounds.

Some functions run out of registers when compiled for debug,
fpic, with stack frames on 32 bit x86 with clang.
Previously they were enabled based on _DEBUG but that macro
is not set in some build systems. This CL adds DEBUG macro as
well to cover those environments.
