The last 64 events in the event queue will be reserved for release

This patch changes from a static length event queue (512) to one that
starts at 128 and grows to 4096 as it overflows, logging each time it
grows.
This change also allows for multiple backtraces to be printed when the
server is wedged rather than just one. This increased sampling should
help identify the true hog in cases where one backtrace might be
insufficient.

miPointerSetPosition traditionally took coordinates on a per-screen basis,
triggering a screen switch when these went out-of-bounds. For absolute
devices, this prevented screen crossing in the negative x/y direction.
This patch changes the event generation patch to handle screen coordinates
in a desktop range (i.e. all screens together). Screen switches are
triggered when these coordinates are not on the current screen.
This unifies the pointer behaviour of single ScreenRec multihead and
multiple ScreenRecs multihead in that the cursor by default moves about the
whole screen rather than be confined to one single screen. The
transformation matrix may then be used to actually confine the cursor to the
screen again.
Note: fill_pointer_events has to deal with several different coordinate
systems. Make sure you read the comment before trying to understand the code.

Don't switch between doubles and ints in the caller, instead take doubles in
miPointerSetPosition and do the conversion there. For full feature we should
change everything down from here for doubles too.
Functional change: previously we'd restore the remainder regardless of
screen switching/confinement (despite what the comment said). Now,
screen changing or cursor constraints will cause the remainder be clipped
off. This should happen for cursor constraints but arguably not for screen
crossing.
This also corrects a currently wrong comment about miPointerSetPosition's
input coordinates.

Expand what this does to print the event content and a backtrace, so at
least we know where we're coming from. Only the first 32 bytes are printed
since if something goes wrong, the event we have is almost certainly an
xEvent or xError, both restricted to 32 bytes.

This is not a straightforward search/replacement due to a long-standing
issue.
dev->u.master is the same field as dev->u.lastSlave. Thus, if dev is a master
device, a check for dev->u.master may give us false positives and false
negatives.
The switch to IsFloating() spells out these cases and modifies the
conditions accordingly to cover both cases.

The subtype in the DGA event is the core type and all ET_ event types (where

will work as required and assign the right master device.
Fixes a crasher bug on keyboard devices with valuators. If a device sends a
motion event while grabbed and a DGA client is active (but has not selected
input through DGA), the valuator event is posted through the VCK and
eventually results in a NULL-pointer dereference on dev->valuator.
