Add plumbing to allow creation of per display surface out fence.
Currently enabled only on android, since the system expects a valid
fd in ANativeWindow::{queue,cancel}Buffer. We pass a fd of -1 with
which native applications such as flatland fail. The patch enables
explicit sync on android and fixes one of the functional issue for
apps or buffer consumers which depend upon fence and its timestamp.
v2: a) Also implement the fence in cancelBuffer.
b) The last sync fence is stored in drawable object
rather than brw context.
c) format clear.
v3: a) Save the last fence fd in DRI Context object.
b) Return the last fence if the batch buffer is empty and
nothing to be flushed when _intel_batchbuffer_flush_fence
c) Add the new interface in vbtl to set the retrieve fence
v3.1 a) close fd in the new vbtl interface on none Android platform
v4: a) The last fence is saved in brw context.
b) The retrieve fd is for all the platform but not just Android
c) Add a uniform dri2 interface to initialize the surface.
v4.1: a) make some changes of variable name.
b) the patch is broken into two patches.
v4.2: a) Add a deinit interface for surface to clear the out fence
v5: a) Add enable_out_fence to init, platform sets it true or
false
b) Change get fd to update fd and check for fence
c) Commit description updated
v6: a) Heading and commit description updated
b) enable_out_fence is set only if fence is supported
c) Review comments on function names
d) Test with standalone patch, resolves the bug
v6.1: Check for old display fence reverted
v6.2: enable_out_fence initialized to false by default,
dri2_surf_update_fence_fd updated, deinit changed to fini
