Check for NULL pointer (which can be returned for multiple reasons)
before trying to dereference it to add privates. To avoid memory leak
in error path, delay malloc of privates until we're ready to add them.
In case we do return NULL up through SyncInitDeviceIdleTime, handle the
possibility of getting NULL passed back down to SyncRemoveDeviceIdleTime.

RELOCATE_PROJECTROOT is AC_DEFINED in configure.ac, but currently has no effect
as it doesn't appear in any AC_CONFIG_HEADER header.
When packaged for Windows, we do not have a unix-style filesystem tree, where
file needed by the X server can be found in fixed, absolute paths under the
prefix (PROJECTROOT).
Instead, the filesystem tree containing files needed by the X server and clients
will be installed with the directory containing the X server executable as the
root directory of that tree.
(Typically, this will be in the Program Files directory, which does not have a
fixed name, as it can be moved, localized, or added to to indicate x86 or x64
binaries)
So, RELOCATE_PROJECTROOT is used to make a native Windows build of the X server
look for various files (fonts, xkb data) in locations relative to the X server
rather than at absolute paths, by translating those paths at run-time.
Additionally the XKEYSYMDB, XERRORDB, XLOCALEDIR env vars checked by libX11 are
set appropriately for clients started by the X server.

DGA only handles master devices but it does intercept slave device events as
well (since the event handlers are per event type, not per device).
The DGA code must thus call into UpdateDeviceState to reset the button/key
state on the slave device before it discards the remainder of the event.
Test case:
- Passive GrabModeSync on VCP
- Press button
- Enable DGA after ButtonPress
- AllowEvents(SyncPointer)
- Release button
The button release is handled by DGAProcessPointerEvent but the device state
is never updated, so the slave ends up with the button permanently down.
And since the master's button state is the union of the slave states, the
master has the button permanently down.

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.

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.
