8c1d7c702e This patch accomplishes the following: 
-- Auto-generates HAVE_LOCALE_H macro and adds it to jconfig.h (this is used by rdjpgcom.c.)
-- Reconciles the description and ordering of macros between config.h.in and jconfig.h.in, so the two files can be easily diffed.
-- Eliminates the use of the autoheader-generated config.h in the project and moves relevant internal-only macros into a new file, jconfigint.h.  This is to avoid "already defined" warnings in files that were including both config.h (to get the internal autotools package information or the INLINE definition) and jconfig.h.

2de8e97989 Add option to use lambda weighting table 
Different lambda values may be used for each frequency in DCT domain.
The weighting table is currently not configurable but can be
enabled/disabled with cinfo-> use_lambda_weight_tbl

6f168e4f80 Add parameters to cjpeg to tune for different metrics 
-tune-psnr, -tune-ssim and -tune-hvs-psnr are added to cjpeg to control
the trellis quantization process and optimize output for PSNR, SSIM and
HVS-PSNR distortion metrics

d200b2c144 Initial implementation of trellis quantization 
A new pass type trellis_pass is added. It defines a pass where trellis
quantization is done in the quantize_trellis() function.
Trellis quantization can be enabled by setting use_moz_defaults to 2 or
by using the -trellis option in cjpeg
Note that trellis does currently not work with scan optimization. Scan
optimization is disabled when trellis is enabled.
