Fix google-explicit-constructor warnings in system/core.
* Declare explicit conversion constructors.
* Add NOLINT for implicit conversion constructors.
* Fix also some misaligned indendations.

Remove qemu_tracing dependency.
The feature is not implemented anymore (and has been for a very long time).
Moreover, this will allow us to cleanup hardware/ from any QEMU-specific
items.

libutils: Fix integer overflows in VectorImpl.
Use external/safe-iop to check for overflows on arithmetic
operations.
Also remove an unnecessary copy of Vector/SharedBuffer from
codeflinger and use the copy from libutils instead.
Note that some of the unit tests are somewhat useless due to
test-runner limitations : gtest's ability to filter on abort message
doesn't work when combined with messages formatted by android's logging
system.

move tinyutils into its own namespace
I was fed-up with the constant conflicts in Eclipse
with the "libutils" version.
Also fix a few copyright notices.

Add MIPS support to pixelflinger.
See the comment-block at the top of MIPSAssembler.cpp for
implementation overview.

Adds support for UBFX to JIT and Disassembler
This introduces UBFX instruction generation abilities to the Pixelflinger JIT,
and also modifies the component extraction function to generate the
instruction.
The extract function contains defines to prevent generation of UBFX on pre-v7
cores. The JIT itself retains the ability to produce the instruction even on
v5/6.
This patch only generates UBFX when MOV, AND or BIC can't be used. Based on
the TRM, this appears to be faster on A9 than using UBFX in all cases.
On startup, Pixelflinger JITs three chunks of code. UBFX improves these as
follows:
00000077:03515104_00000000_00000000
(Blends a single colour into an RGB565 buffer.)
Before: 27 inst/pixel, After: 24 inst/pixel, Improvement: 12.5%
00000077:03545404_00000A01_00000000
(Blends RGBA8888 texture into an RGB565 buffer using alpha.)
Before: 30 inst/pixel, After: 27 inst/pixel, Improvement: 11.1%
00000077:03545404_00000A04_00000000
(Blends RGB565 texture into an RGB565 buffer using alpha.)
Before: 29 inst/pixel, After: 27 inst/pixel, Improvement: 7.4%

Adds UXTB16 support to Pixelflinger
* Add support for UXTB16 to the disassembler
* Add encoding of the UXTB16 instruction to the Pixelflinger JIT.
Introducing the UXTB16 instruction allows removal of some masking code, and is
beneficial from a pipeline point of view - lots of UXTB16 followed by MUL
sequences.
Also, further rescheduling and use of SMULWB brings extra performance
improvements.
* Use UXTB16 in bilinear filtered texturing
Uses UXTB16 to extract channels for SIMD operations, rather than creating and
ANDing with masks. Saves a register and is faster on A8, as UXTB16 result can
feed into first stage of multiply, unlike AND.
Also, used SMULWB rather than SMULBB, which allows removal of MOVs used to
rescale results.
Code has been scheduled for A8 pipeline, specifically aiming to allow
multiplies to issue in pipeline 0, for efficient dual issue operation.
Testing on SpriteMethodTest (http://code.google.com/p/apps-for-android/) gives
8% improvement (12.7 vs. 13.7 fps.)
SMULBB to SMULWB trick could be used in <v6 code path, but this hasn't been
implemented.
