This patch adds support to make libcutils create and use memfd where
possible, instead of ashmem.
The libcutils library is made dynamic, since apps are still sending over
ashmem FDs to processes and we are working on moving those apps away
from ashmem. The best we can do for that is make the library work, and
force apps in the long run to move away from directly using ashmem.
Due to further complications mentioned in the 'NOTE' section of the
patch, memfd is kept disabled for now, so nothing changes yet. To enable
it, set the sys.use_memfd property (check user_debug build).

Should use android/log.h instead of cutils/log.h as a good example
to all others. Adjust header order to comply with Android Coding
standards.

Use correct memory ordering.
Start the reference count at zero instead of one, thus giving us a
chance to actually deallocate something.
Remove remaining (unused) inclusions of cutils/atomic.h from
libpixelflinger.

This reverts commit ab5265ebe6.
This broke the mips64 build (which, stupidly, I hadn't tested):
system/core/libpixelflinger/codeflinger/MIPS64Assembler.h:24:35: fatal error: tinyutils/KeyedVector.h: No such file or directory
#include "tinyutils/KeyedVector.h"

Added ARMtoMips64Assembler class that translates ARM instructions to MIPS64r6
instructions.
Added MIPS64r6 assembly implementations for col32cb16_blend and t32cb16_blend
functions.
Added MIPS32r2 assembly implementation for col32cb16_blend function.
Added tests for MIPS64r6 (assembler, disassembler and assembly implementation
functions).
Added MIPS32 tests for assembly implementation functions.
Minor bug fixes for MIPS32r2 branch.

* Explicitly specify default .align 0.
* Use standard ldmfdlo instruction.
* Before and after gas outputs are identical,
with align 0 sections.
* Objdump showed .text/.data/.bss section alignment
attributes are 2^0 from gas and 2^2 from llvm
assembler. These .S files might be working when
compiled by gas, but llvm assembler's output should
be more correct or conservative.

pixelflinger should not be used for new projects and should be moved out
of system/core at some point. As the first step, move all its headers
under system/core/libpixelflinger/include and update its Android.mk
files so they're not referring to the absolute system/core path anymore.

For now, use generic C code instead of generated mips instructions,
in the same manner as used on x86 and x86_64 targets.

cacheflush doesn't exist on LP64 any more, and gcc's
__builtin___clear_cache is better in every way. Use it instead.

See the comment-block at the top of Aarch64Assembler.cpp
for overview on how AArch64 support has been implemented
In addition, this commit contains
[x] AArch64 inline asm versions of gglmul series of
functions and a new unit test bench to test the
functions
[x] Assembly implementations of scanline_col32cb16blend
and scanline_t32cb16blend for AArch64, with unit
test bench

There is no need to include codeflinger test function in
libpixelflinger. Instead, it should exist in test-opengl-codegen.
