[igt-dev] [PATCH i-g-t v2 0/1] Fix the multiprocess mode of intel allocator

In the multiprocess mode all requests to the allocator are
processed in the parent. However, in certain scenarios
(for example gem_exec_capture at pi), a child process may want
to create an allocator instance using its own private file
desriptor.  Thus all ioctls used to determine available gtt size
must be called in the child process and not in the parent.

This patch implements the above change.

v2: Test allocators for private and shared contexts in
    multiprocess mode.
