This commit is aimed at drastically improving the support for the CL/GL
sharing
extension on linux. The current support is not really usable as it only
supports a few texture format, and only on EGL contexts. It is also
pretty
buggy since it requires the texture to be bound when placing the CL call
to
share it which is just plain wrong and will not work in many
applications.
This new version makes used of the "official" interop extension from
MESA
which is available for GLX and EGL contexts, allows sharing of buffers
and
not just texture and supports many more formats.
This is still far from being a fully compliant / full featured version
of
the extension, but it's a big step forward in my opinion and allows to
run
some real applications.
I've tested gr-fosphor (SDR spectrum display) and Davinci Resolve as
examples.
Both of theses don't work without theses improvements.

- Given a Base Pointer passed into Get Peer Allocation, then the base
pointer is used in the map of the new allocation to the virtual memory.
- Enables users to use the same pointer for all devices in Peer To Peer.
- Currently unsupported on reserved memory due to mapped and exec
resiedency of Virtual addresses.
