De-queuing Windows messages and X events happens in the same thread of
execution. Draining the windows message queue can lead to the X event queue
overflowing if lots of those windows messages cause X events (e.g. if a keyboard
macro program has just dumped thousands of keypresses into the Windows message
queue). See the mailing list thread [1] for more details.
Processing one Windows message per wakeup, rather than all of them gives the X
server a chance to do stuff as well after each message.

This places a pointer to the grab related to a TouchListener directly
in the TouchListener structure rather than hoping to find the grab
later on using the resource ID.
Passive grabs have resource ID in the resource DB so they can be
removed when a client exits, and those resource IDs get copied when
activated, but implicit grabs are constructed on-the-fly and have no
resource DB entry.

The base group is not brought into range and, therefore, using it as an array
index crashed the X server. Also, at this place, we should ignore locked
groups, but not latched groups. Therefore, use sum of base and latched groups,
brought into range.
Reproducible with:
key <FK07> {
type= "ONE_LEVEL",
symbols[Group1]= [ NoSymbol ],
actions[Group1]= [ LatchGroup(group=-1, clearLocks) ]
};
And hitting F7 will exceed the group level and access arbitrary memory.

The loop above the previous call may end up triggering other
handlers attaching to the same function slot, so unwrapping
the handler after that could leave the just attached handler
in a dangling but not unset state.
This issue was most visible on the XO, where destroying a
window with an animated cursor set and running would trigger
this inconsistent state, never calling the miSpriteBlockHandler
again after the animated cursor is unset.

Different miPointerSpriteFuncRec implementations do a varying
business at ultimately calling miPointerUpdateSprite(), this
particularly fails when using the plain mi sprite on touch events,
where the sprite is just moved/updated on cursor changes.
So, ensure miPointerUpdateSprite() is called generically for
pointer emulating touch events as with regular motion events.

Commit 31bf81772e changed the clientState field
from a signed int to a signed int 2-bit bitfield. The ClientState enum that is
expected to be assigned to this field has four values: ClientStateInitial (0),
ClientStateRunning (1), ClientStateRetained (2), and ClientStateGone (3).
However, because this bitfield is signed, ClientStateRetained becomes -2 when
assigned, and ClientStateGone becomes -1. This causes warnings:
test.c:54:10: error: case label value exceeds maximum value for type [-Werror]
test.c:55:10: error: case label value exceeds maximum value for type [-Werror]
The code here is a switch statement:
53 switch (client->clientState) {
54 case ClientStateGone:
55 case ClientStateRetained:
56 [...]
57 break;
58
59 default:
60 [...]
61 break;
62 }
It also causes bizarre problems like this:
client->clientState = ClientStateGone;
assert(client->clientState == ClientStateGone); // this assert fails
Also change the signedness of nearby bitfields to match.
