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.

libjpeg-turbo has never supported non-ANSI compilers, so get rid of the crufty SIZEOF() macro. It was not being used consistently anyhow, so it would not have been possible to build prior releases of libjpeg-turbo using the broken compilers for which that macro was designed.

Remove MS-DOS code and information, and adjust copyright headers to reflect the removal of features in r1307 and r1308. libjpeg-turbo has never supported MS-DOS, nor is it even possible for us to do so.

Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

Work around an issue in Visual C++ 2010 and 2013 that was causing the 256-bit bitmap test in the regression tests to fail. More specifically, when optimization is enabled in these versions of Visual C++, the optimizer seems to get confused by the following code block:
delta = cur0 * 2;
cur0 += delta; /* form error * 3 */
errorptr[0] = (FSERROR) (bpreverr0 + cur0);
cur0 += delta; /* form error * 5 */
bpreverr0 = belowerr0 + cur0;
cur0 += delta; /* form error * 7 */
Each time cur0 is incremented by delta, the compiled code doubles the value of delta (WTF?!) Thus, by the time the end of the block is reached, cur0 is equal to 15 times its former self, not 7 times its former self as it should be. At any rate, it was a lot simpler to just refactor the code so that it uses multiplication.

Further examination of the code reveals that this change is unnecessary. The histogram stores a count of each color in the image, so it will always contain at least one non-zero element, and thus the total can never be zero. Since the histogram is generated from the image data and not read from the header, there is no chance that header corruption would affect it.

Some of the IJG headers say "Modified by", so clarify that our "Modifications" are not referring to these.
