Even if flushing the command buffer doesn't succeed, the
G2D calls would still return zero. Fix this by just passing
the flush return code.
In fact error handling currently ignores the fact that
g2d_add_cmd() can fail. This is going to be handled
in a later patch.

This reverts commit fde4969176.
The commit adds an API that does not seem flexible enough to be used in
current open-source projects. Additionally it adds a hidden dependency
of libudev, which when used in mesa caused grief when combined with
Steam('s runtime).
Let's revert this for now and add a tweaked API later on that can be
used in mesa/xserver.

This enables us to check for overlay planes which are located
'below' the primary plane.
Since the alpha value only has an effect when creating surfaces
with an alpha-pixelformat this doesn't affect the regular
XRGB8888 primary surface.

Add a flag allowing Nouveau to specify that an object should be coherent
at allocation time. This is required for some class of objects like
fences which are randomly-accessed by both the CPU and GPU. This flag
instructs the kernel driver to make sure the object remains coherent
even on architectures for which coherency is not guaranteed by the bus.

In order to use userptr, the kernel tracks the owner's mm with a
mmu_notifier. Setting that is very expensive - it involves taking all
mm_locks and a stop_machine(). This tracking lives only for as long as
the client is using userptr objects - so if the client allocates then
frees a userptr in a loop, we will be executing that heavyweight setup
everytime. To ammoritize this cost, just leak the test bo and the single
backing page we use for detecting userptr.
v2: Free the object and memory when bufmgr is destroyed.

Only the 'offsets' array was initialized to zero.
Since bo_create only sets the handles which are
necessary, were we passing garbage data to the
kernel when calling drmModeAddFB2 later.
The issue only seems to appear when passing e.g.
NV12 data to the kernel, a case where not only
handles[0] is used. I therefore also removed the
corresponding comment.
v2: Do the same for set_mode(), set_cursors()
and test_page_flip().
