libjpeg-turbo: Upgrade to 1.5.1
The changes from 1.4.2 to 1.5.1 include
a big amount of fixes and huge performance improvements.
As highlights there is a full ARM 64-bit (ARMv8) NEON SIMD
implementation which improves compression of full-color JPEGs
by about 2-2.5x on average on Cortex-A53 and Cortex-A57 cores.
Also SIMD acceleration for Huffman encoding on NEON-capable
ARM 32-bit and 64-bit platforms was added.
Performance on x86/x86_64 was also improved by
adding better optimized SSE2 routines.
For the full changelog, please see the ChangeLog.md
file.
Partial decoding optimizations, the security fix
to adress b/27494207 and the fix for the AARCH64
conformance issueare present in the release.
The README.android file was edited to reflect this.
The configuration files were regenerated
and all Android specific changes were applied.

Reformat code per Siarhei's original patch (to clearly indicate that the offset instructions are completely independent) and add Siarhei as an individual author (he no longer works for Nokia.)

Subject: [PATCH] ARM: Faster NEON yuv->rgb conversion for Krait and Cortex-A15
The older code was developed and tested only on ARM Cortex-A8 and ARM Cortex-A9.
Tuning it for newer ARM processors can introduce some speed-up (up to 20%).
The performance of the inner loop (conversion of 8 pixels) improves from
~27 cycles down to ~22 cycles on Qualcomm Krait 300, and from ~20 cycles
down to ~18 cycles on ARM Cortex-A15.
The performance remains exactly the same on ARM Cortex-A7 (~58 cycles),
ARM Cortex-A8 (~25 cycles) and ARM Cortex-A9 (~30 cycles) processors.
Also use larger indentation in the source code for separating two independent
instruction streams.

Subject: [PATCH] ARM: NEON optimized yuv->rgb565 conversion
The performance of the inner loop (conversion of 8 pixels):
* ARM Cortex-A7: ~55 cycles
* ARM Cortex-A8: ~28 cycles
* ARM Cortex-A9: ~32 cycles
* ARM Cortex-A15: ~20 cycles
* Qualcomm Krait: ~24 cycles
Based on the Linaro rgb565 patch from
https://sourceforge.net/p/libjpeg-turbo/patches/24/
but implements better instructions scheduling.

.func/.endfunc are only necessary when generating STABS debug info, which basically went out of style with parachute pants and Rick Astley. At any rate, none of the platforms for which we're building the ARM code use it (DWARF is the common format these days), and the .func/.endfunc directives cause the clang integrated assembler to fail (http://llvm.org/bugs/show_bug.cgi?id=20424).
