Update Chromium's copy of libjpeg-turbo to the latest upstream
release (v2.0.90) and re-apply our local changes documented in
README.chromium.
Cherry-pick two additional changes from upstream to fix bugs found
by fuzzers:
1) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ccaba5d7894ecfb5a8f11e48d3f86e1f14d5a469
2) https://github.com/libjpeg-turbo/libjpeg-turbo/commit/c7ca521bc85b57d41d3ad4963c13fc0100481084
Significant changes provided by this update:
1) A large performance boost to JPEG encoding due to an improved
Huffman encoding implementation.
2) The complete removal of Arm Neon assembly code. This allows Arm's
control-flow integrity security features (Armv8.3-A Pointer
Authentication and Armv8.5-A Branch Target Identification) to be
switched on with the appropriate compiler flags.

In order to apply some performance updates from ARM, we need to update
libjpeg-turbo. These performance updates have yielded a 50% speedup on
some devices.
This CL updates our copy of libjpeg-turbo to v2.0.1 and re-applies our
local patches. This patch also deletes some extra files which were not
being used locally.
Update our local patch that was applied to fix http://crbug.com/398235
(https://codereview.appspot.com/229430043/). The original patch
incorrectly removed "& 0xFF" which limited an array index to within
that array's bounds (effectively reverting
https://github.com/libjpeg-turbo/libjpeg-turbo/commit/fa1d18385d904d530b4aec83ab7757a33397de6e).
Restore the mask, making the array access safe and fixing a graphical
glitch which would otherwise be introduced by this change.

Make the fast path Huffman decoder fallback to the slow decoding path if
the Huffman decoding bit sentinel > 16, this to match libjpeg6b decoding
by reproducing the exact behavior of jpeg_huff_decode().
When this sentinel check is missing (see bug), libjpeg_turbo can produce
two (or more) different decoded images for the same input data depending
on how transport systems (eg., networks) packetize the data for delivery
to end-systems, web browsers for example.
Note: libjpeg6b produces the same decoded image, irrespective of how the
input data is placed in network packets. This fix makes libjpeg_turbo do
the same for compat with libjpeg6b.

Remove google.jdmarker.patch, since the fixes for CVE-2013-6629
and CVE-2013-6630 are upstream most everywhere now [1]. Version
number to 1.3.1 (config.h, jconfig.h).
README.chromium: "Fixed valgrind error" patch was upstreamed in
r839 http://sourceforge.net/p/libjpeg-turbo/code/839. The r1188
cherry-pick was put in config.h, say that.

This change lands the original libjpeg-turbo 1.0.1 (source files only) and NASM 2.09.2 (required for assembling .asm files on Windows) to "deps/third_party". I will send more changes to land its build files and patches to integrate it into Chrome.
