Upgrade libjpeg_turbo to 1.3.1 (r1219)

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.

 externally visible functions to chromium_* so that we can avoid conflicts that
 arise when system libraries attempt to use our libjpeg. Also, we applied the
 following changes which are not merged to upstream:
+
 * Added the 'private_extern' flags on Mac (or the 'hidden' flags on Linux) to
   all the global symbols in '.asm' files to prevent making them external ones.
 * Supported motion-JPEG frames that do not have DHT markers.
-* Fixed valgrind errors.

 The 'google.patch' file represents our changes from the original
-libjpeg-turbo-1.2. With those applied, also patch in google.jdmarker.patch to
-better handle multiple SOS CSi values and their ordering, and to 0 unused DHT
-huffman values at creation time.
