The difference between the two is that XF86 has the clip helper that
lets you upload less data when rendering video that's clipped. I
don't think that's really worth the trouble, especially in a world of
compositors, so I've dropped it to get to shared code.
It turns out the clipping code was broken on xf86-video-intel anyway.
To reproduce, run without a compositor, and use another window to clip
the top half of your XV output on the glamor XV adaptor: the rendering
got confused about which half of the window was being drawn to.

v5: Don't crash when stipple damage tracker is destroyed
The stipple damage tracker is automatically destroyed when the
associated stipple pixmap is destroyed. When this happens, just
clear the pointer from the GC rather than calling
glamor_invalidate_stipple; that function would call

Glamor has a mode where pixmaps will be constructed from numerous
small FBOs. This allows testing of the tiled pixmap code without
needing to create huge pixmaps.
However, the render glyph code assumed that it could create a pixmap
large enough for the glyph atlas. Instead of attempting to fix that
(which would be disruptive and not helpful), I've added a new pixmap
creation usage, GLAMOR_CREATE_NO_LARGE which forces allocation of a
single large FBO.
Now that we have pixmaps with varying FBO sizes, I then went around
and fixed the few places using the global FBO max size and replaced
that with the per-pixmap FBO tiling sizes, which were already present
in each large pixmap.
Xephyr has been changed to pass GLAMOR_CREATE_NO_LARGE when it creates
the screen pixmap as it doesn't want to deal with tiling either.

The common pattern is to do nested if statements making calls to
prepare_access() and then pop those mappings back off in each set of
braces. Some cases checked for src == dst to avoid leaking mappings,
but others didn't. Others didn't even do the nested mappings, so a
failure in the outer map would result in trying to umap the inner and
failing.
By allowing nested mappings, we can fix both problems by not requiring
the care from the caller, plus we can allow a simpler nesting of all
the prepares in one if statement.
