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.

bc56b754e1 Get rid of the HAVE_PROTOTYPES configuration option, as well as the related JMETHOD and JPP macros. libjpeg-turbo has never supported compilers that don't handle prototypes. Doing so requires ansi2knr, which isn't even supported in the IJG code anymore.

52ded87680 Remove all of the NEED_SHORT_EXTERNAL_NAMES stuff. There is scant information available as to which linkers ever had a 15-character global symbol name limit. AFAICT, it might have been a VMS and/or a.out BSD thing, but none of those platforms have ever been supported by libjpeg-turbo (nor are such systems supported by other open source libraries of this nature.)
