libjpeg 8b

[willimm]

Yes, yet another libjpeg version. I hear you cry. Good thing that there are no ABI changes in this release. The changes are (lifted from the change.log file):

jpegtran now supports the same -scale option as djpeg for "lossless" resize.
An implementation of the JPEG SmartScale extension is required for this
feature.  A (draft) specification of the JPEG SmartScale extension is
available as a contributed document at ITU and ISO.  Revision 2 or later
of the document is required (latest document version is Revision 3).
The SmartScale extension will enable more features beside lossless resize
in future implementations, as described in the document (new compression
options).

Add sanity check in BMP reader module to avoid cjpeg crash for empty input
image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error).

Add data source and destination managers for read from and write to
memory buffers.  New API functions jpeg_mem_src and jpeg_mem_dest.
Thank to Roberto Boni from Italy for the suggestion.

So yea, I think we should consider this for 6.5.
