Contributor notes:

***********************************
Yet another external patch, the attached one adds an EXTERNAL_XINERAMA
option that allows to link to the system's libXinerama library rather
than using the internal copy of it.

I hoped that doing so would have fixed jconsole appearing between the
two screens, but it didn't do so (gonna debug it soon); in the mean
time it's still a nice thing to use it shared, as for those who
actually use Xinerama, the library is for sure already loaded at any
given time.
***********************************

The patch is available in the Evaluation.
