last.scroll remained on the last-submitted scrolling value but last.valuator
was changed whenever the slave device changed. The first scrolling delta
after a switch was then calculated as (last.scroll - new abs value), causing
erroneous scrolling events.
Test case:
- synaptics with a scrolling method enabled, other device with 3+ axes (e.g.
wacom)
- scroll on touchpad
- use other device
- scroll on touchpad
The second scroll caused erroneous button press/release events.

This doesn't really implement early accept as it should. Ideally, the
server should send end events to all subsequent touch clients as soon as
an early accept comes in. However, this implementation is still protocol
compliant. We can always improve it later.

For expediency, it made sense to always have the X and Y axes set for
direct touch device event propagation. The last X and Y values are
stored internally. However, indirect device touch event propagation
does not depend on the touch's X and Y values. Thus, we don't need to
set the values for every indirect touch event.
On top of this, the previous X and Y values aren't stored for indirect
touches, so without this change the axes get erroneously set to 0.

When {XI,X,}AllowEvents is called, the timestamp is compared against the
grab time to ensure that the request pertains to the current grab in the
server. While many clients may use CurrentTime (client-side), the
timestamp of the event causing the grab is also valid.
This change ensures that the server's notion of the grab time is the
time of the event that activated the grab rather than the time that the
grab is actually activated.
This bug was exposed through nested touch then pointer grabs.

dixLookupWindow uses dixLookupDrawable internally, which returns
BadMatch when the XID matches a non-Window drawable. Users
of dixLookupWindow don't care about this, just that it's not
a valid Window.
This is a generalised version of the fix for X.Org Bug 23562,
where GetProperty was incorrectly returning BadMatch. Auditing other
window requests, all that I checked would incorrectly return BadMatch
in these circumstances. An incomplete list of calls that could
incorrectly return BadMatch is: ListProperties, SetSelectionOwner,
{Destroy,Map,Unmap}{,Sub}Window.
None of the callers of dixLookupWindow, except for GetProperty, check

Forwarding proxies like sshd will appear to be local, even though they
aren't really. This leads to weird behaviour for extensions that truly
require running under the same OS services as the client, like MIT-SHM
and DRI2.
Add two new legal values for the initial connection's byteOrder field,
'r' and 'R'. These act like 'l' and 'B' respectively, but have the side
effect of forcing the client to be treated as non-local. Forwarding
proxies should attempt to munge the first packet of the connection
accordingly; older servers will reject connections thusly munged, so the
proxy should fall back to passthrough if the munged connection attempt
fails.

Note: this commit is a retroactive commit extracted from a series of ~50
commits and may thus appear a bit more complicated than what you'd write out
from scratch.
Pointer processing tree is roughly:
- ProcessOtherEvents
- ProcessTouchEvents
- DeliverTouchEvents
- DeliverTouchBeginEvent|DeliverTouchEndEvent|...
- DeliverOneTouchEvent
Also hooks up the event history playing to the right function now.

If touch client has not registered for ownership events and a grab above
that client is rejected, the client needs to receive the complete event

The history currently doesn't really do fancy overflow handling. We assume
that the first TOUCH_HISTORY_SIZE events are the important ones and anything
after that is dropped. If that is a problem, fix the client that takes > 100
event to decide whether to accept or reject.
Events marked with TOUCH_CLIENT_ID or TOUCH_REPLAYING must not be stored in
the history, they are events created by the DIX to comply with the protocol.
Any such event should already be in the history anyway.
