[OpenIndiana-discuss] Update of JPEG libraries

[Aurélien Larcher]

Hi Peter,

I believe that libjpeg-turbo ought to be a straight drop-in replacement for

Bob Friesenhahn mentioned that libjpeg-turbo could be flaky in some
edge-cases and possible concerns regarding incorrect memory allocation.
Some references related to CVEs or Mozilla and Chrome development seemed to
confirm that.Therefore I just chose to setup things in a conservative way
and if/when the time comes we can switch the links to libjpeg-turbo 6b.
In any case, I do not have time to investigate further (nor the will,
considering priorities), so it is better to break things in several
stages... At the end of the day since Debian, Ubuntu, Fedora and Chrome
ended up using libjpeg-turbo and people use jpeg_mem_src/dst I think we'll
end up slowly with libjpeg8-turbo as default.
