Merge libjpeg-turbo r1325

* commit 'b8d044a666056d4d8d28d7a5d0805ac32b619b36': (58 commits)
  Big oops.  wrjpgcom on Windows was being built using the rdjpgcom source.
  Prevent a buffer overrun if the comment begins with a literal quote character and the string exceeds 65k characters.  Also prevent comments longer than 65k characters from being written, since this will produce an incorrect JPEG file.
  Remove VMS-specific code
  Our copyright string is longer than JMSG_LENGTH_MAX, and this was causing a buffer overrun if output_message() was called with msg_code set to JMSG_COPYRIGHT, or if format_message() was called with msg_code set to JMSG_COPYRIGHT and with a buffer of length JMSG_LENGTH_MAX.
  We don't support non-ANSI C compilers
  Allow for building the MIPS DSPr2 extensions if the host is mips-* as well as mipsel-*.  The DSPr2 extensions are little endian, so we still have to check that the compiler defines __MIPSEL__ before enabling them.  This paves the way for supporting big-endian MIPS, and in the near term, it allows the SIMD extensions to be built with Sourcery CodeBench.
  SIMD-accelerated int upsample routine for MIPS DSPr2
  Fix MIPS build
  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.
  Further copyright header cleanup
  Further copyright header cleanup
  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.
  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.)
  Clean up code formatting in the SIMD interface functions
  SIMD-accelerated NULL convert routine for MIPS DSPr2
  Fix build, which was broken by the checkin of the MIPS DSPr2 accelerated smooth downsampling routine.  Until/unless other platforms include SIMD support for that function, it's just easier to #ifdef around it rather than adding stubs for the other platforms.
  Fix error in MIPS DSPr2 accelerated smooth downsample routine
  SIMD-accelerated h2v2 smooth downsampling routine for MIPS DSPr2
  Minor tweak to improve code readability
