1.2.1+svn853HEADmasterLinaro-LEB

  * update to stable release 1.2.1 r853
   * Cosmetic fixes to argument lists
   * Added flags to the TurboJPEG API that allow the caller to force
     the use of either the fast or the accurate DCT/IDCT algorithms
     in the underlying codec.
   * More recent versions of autoconf add -traditional-cpp to the CPP
     flags, which causes jsimdcfg.inc.h to not preprocess correctly
     unless we expand all of the instances of the #definev macro.
   * Fixed regression caused by a bug in the 32-bit strict memory access
     code in jdmrgss2.asm (contributed by Chromium to stop valgrind from
     whining whenever the output buffer size was not evenly divisible by
     16 bytes.)  On Linux/x86, this regression generated incorrect
     pixels on the right-hand side of images whose rows were not 16-byte
     aligned, whenever fancy upsampling was used.  This patch also
     enables the strict memory access code on all platforms, not just
     Linux (it does no harm on other platforms) and removes a couple of
     pcmpeqb instructions that were rendered unnecessary by r835.
   * Accelerated 4:2:2 upsampling routine for ARM (improves
     performance ~20-30% when decompressing 4:2:2 JPEGs using
     fancy upsampling)
   * Eliminate the use of the MASKMOVDQU instruction, to speed
     up decompression performance by 10x on AMD Bobcat embedded
     processors (and ~5% on AMD desktop processors.)
   * add tjbench to libjpeg-turbo-test packages
   * Guard against num_components being a ridiculous
     value due to a corrupt header
   * Preserve all 128 bits of xmm6 and xmm7
