operations such as revalidating the tree and generating exposures when only
changing a window's input shape.

Reverts part of the effects of 518f3b189b,
"mi: don't thrash resources when displaying the software cursor across
screens". The per-screen cache is preserved, and the GCs are still
allocated eagerly, but now it doesn't construct pRootPicture until
somebody attempts to draw an ARGB cursor.
I noticed crashes in Xnest, which doesn't support the RENDER extension,
but I suspect other DDXes that support disabling that extension would
have had issues as well.

ActivateDevice was ignoring errors from DeviceCursorInitialize, so
cursor-related calls failed later. Jeremy Huddleston saw that crash in
miPointerConstrainCursor, while with Xvfb I saw it in
miSpriteRealizeCursor.
miDCDeviceCleanup frees any non-NULL GCs. miDCDeviceInitialize calls
Cleanup on any failure, but if it failed early then some of the pointers
in the miDCBufferPtr were garbage. Switch from malloc to calloc to
ensure everything's initialized safely first.
With these two fixes, if CreateGC fails then the server gracefully fails
in FatalError instead of segfaulting.

If filter is NoEventMask (aka CantBeFiltered), grab is null, and the
first event is not in the set of "critical events", then TryClientEvents
simply calls WriteEventsToClient. In that case, it returns 0 for fake or
dead clients, and 1 otherwise. Inline for this special case.

Both functions compute a set of spans and either fill them immediately
or accumulate them into a caller-provided buffer.
Computing the spans used only the miTranslate and lineWidth fields of
pGC, and neither could have been changed by the initial
ChangeGC/ValidateGC pair, so it's safe to compute the spans first.
Then both functions consume the spans the same way, so factor that into
a new fillSpans function.

Banked framebuffers are so 1990. As of 7.4 the only drivers remaining
that used this were chips, neomagic, trident, and vesa. vesa only used
it when not using shadowfb, which is broadly undesirable anyway, and no
longer uses it at all as of 2.3.0. neomagic never used it by default,
and support for it is gone in git master. The other two effectively
only ever used it for ISA chips; since ISA support is now gone from
the server, they have been modified to only compile mibank support when
ISA support is available.

This is long overdue. The device events are InternalEvents now (and only one
at a time), diminishing the need for an EventList for the master event.
Furthermore, don't make masterEvent a static since this will interfere if
mieqProcessDeviceEvent is called from somewhere else (e.g. XKB actions).
