Joel Fernandes 519440468b Add support for memfd
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).

Mark Salyzyn 66ce3e08c5 system/core Replace cutils/log.h with android/log.h
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.

Hans Boehm e74dec4a39 Fix reference counting for Assembly
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 broke the mips64 build (which, stupidly, I hadn't tested):

Ljubomir Papuga ab5265ebe6 Add MIPS64r6 support for libpixelflinger
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.

Chih-Hung Hsieh 7244cf2aa5 To compile with llvm integrated assembler.
* 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.

Greg Hackmann 38eb58d2a8 pixelflinger: make self-contained
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.
