sna: Basic copy-on-write support for cloning pixmaps

Otherwise we discard a fill operation that is required to initialise the
pixmap before drawing commences.

Coacher is optimistic that the issue is no longer reproducible on his
machine - and whilst I do not understand the root cause, I am confident
that the kernel code is correct as is our use.

Otherwise we end up cloning the scanout only to leave it dangling if the
client copies the from the front-buffer and then writes to it.

Once cloned, we do not want to use inplace operations and instead force
a copy. However, if we do not relinquish the hints when copying across
the bo, then those hints become stale and lead to corruption.

As Chris mentioned there is a tendency for us to find out more
PCI IDs only when users report. So let's add all new reserved Haswell IDs.
I didn't have better names for this reserved ids and didn't want to use rsvd1
and rsvd2 groups, so I decided to use "B" and "E" that stands for the last
id digit.

When publishing first HSW ids we weren't allowed to use "GT3" codname.
But this is the correct codname and Mesa is using it already.
So to avoid people getting confused why in Mesa it is called GT3 and here
it is called GT2_PLUS let's fix this name in a standard and correct way.

Since the extended use of move_area_to_gpu for partial migration of
render sources, we exposed the lack of handling of upload caches along
that path.

Only upload the portion of the pixmap being used for this rendering
operation, as outside of that may remain undefined and to be written by
the client before a future operation.

There is a tendency for a product to ship based on a 'reserved' PCI-ID
prior to us being notified about it. In other words, the first we find
out about such a product is when customers start complaining about their
shiny new hardware not being supported...

If we skip the migration, we need to avoid using the unitialiased
region. There is no bad consequence as both branches of the if are
no-ops, but it does silence the static checkers and should make the
predicate cheaper.

Probe for i830_dri.so and, if it exists, use that driver in preference
to i915_dri.so for DRI (i.e. GL clients). This was suggested in the
context of distributions supplying i915g as the main DRI driver for
gen3, in which case we need to provide a separate DRI driver for gen2.

If we try to release the framebuffers whilst not DRM_MASTER, the
operation will fail and we will leak the buffers. So do not bother
during the normal expiration to clean the scanout cache if vt switched
away.

There is a workaround that says the first RENDER command following use of
the BLT should be a non-pipelined command. To be safe, emit a MI_FLUSH
before setting up the invariants.

One particular buffer type is quite cunning and simultaneously sets both
CPU/GPU as all damaged (the upload buffer) so be aware when making bold
assertions.
