The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.
v3: Add/remove the XID map from the vendor private thunk, not the
backend. (Kyle Brenneman)

Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.
When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.
When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.
Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

Under glamor, we need to re-create the screen pixmap at the new size
so that we can ask glamor for the associated texture. Fortunately, we
can simply use ephyr_glamor_create_screen_resources to create the new
pixmap.
Because this is being done after the server has started, we need to
walk the window heirarchy and reset any windows pointing at the old
pixmap. I could easily be convinced that this TraverseTree should be
moved to miSetScreenPixmap.

The screen block and wakeup handlers are the only ones which provide a
well known ordering between the wrapping layers; placing these as
close as possible to the server blocking provides a way for the driver
to control the flow of execution correctly.
Switch the shadow code to run in the screen block handler so that it
now occurrs just before the server goes to sleep.
Switch glamor to call down to the driver after it has executed its own
block handler piece, in case the driver needs to perform additional
flushing work after glamor has called glFlush.
These changes ensure that the following modules update the screen in
the correct order:
animated cursors (uses RegisterBlockAndWakeupHandlers dynamically)
composite (dynamic wrapping)
misprite (dynamic wrapping)
shadow (static wrapping)
glamor (static wrapping)
driver (static wrapping)
It looks like there's still a bit of confusion between composite and
misprite; if composite updates after misprite, then it's possible
you'd exit the block handler chain with the cursor left hidden. To fix
that, misprite should be wrapping during ScreenInit time and not
unwrapping. And composite might as well join in that fun, just to make
things consistent.
[v2] Unwrap BlockHandler in shadowCloseScreen (ajax)
[v3] ephyr: Use screen block handler for flushing changes
ephyr needs to make sure it calls glXSwapBuffers after glamor finishes
its rendering. As the screen block handler is now called last, we have
to use that instead of a registered block/wakeup handler to make sure
the GL rendering is done before we copy it to the front buffer.
