Turns out it's really really hard synchronising device state across multiple
duplicated events if they all share the same struct. So instead of doing so,
when the SD changes deep-copy all it's classes into the MD. The MD then has
the same capabilities, but the state can be set separately. This should fix
xkb, key state, repeat etc. problems.
Updating the device state allows us to remove the SwitchCoreKeyboard from the
event gathering, it's all done during event processing now.
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
If we inherited a signal mask from the parent process that ignores SIGUSR1,
then we will send SIGUSR1 to the parent to indicate when we're ready to
accept connections. Unfortunately, we send this notification way too
early, right after creating the sockets rather than just before entering
the main loop.
Move it to just before Dispatch() so we're not lying quite so much.
The smart scheduler itimer currently always fires after each request
(which in turn causes the CPU to wake out of idle, burning precious
power). Rather than doing this, just stop the timer before going into
the select() portion of the WaitFor loop. It's a cheap system call, and
it will only get called if there's no more commands batched up from the
active fd.
This change also allows some of the functions to be simplified;
setitimer() will only fail if it's passed invalid data, and we don't do
that... so make it void and remove all the conditional code that deals
with failure.
The change also allows us to remove a few variables that were used for
housekeeping between the signal handler and the main loop.

XI events can now take the same processing paths as core events, and should do
the correct state changes etc.
There's some cases where XKB will use KeyPress as type for an event to be
delivered to the client. Stuck warnings in, not sure what the correct solution
is yet.
(cherry picked from commit 6334d4e7be with some
additional compile fixes and non-MPX adaptations)
using a hardcoded ProcessKeyboardEvent. Otherwise we lose the ability to
process DeviceKeyEvents after the first key press.
This should be the correct fix now.
(cherry picked from commit 4d5df14f2c)
Using a global array for action filters is bad. If two keyboard hit a modifier
at the same time, releaseing the first one will deactivate the filter and
thus the second keyboard can never release the modifier again.

Set isMaster for VCP/VCK.
Init sprites for master pointer devices.
Pair master kbds with master pointers (1:1 pairing!).
Attach other devices to VCP/VCK.
For now, we don't allow attaching slaves to other slaves, and we don't allow
pairing slaves with other slaves.
Pairing is for master keyboard->master pointer only.
Attaching is for slave device->master device only.
"master" points to the device this device is attached to. Event sent by the
device will also be routed through the master.
master and spriteOwner are mutually exclusive.
* configure.ac,include/dix-config.h.in: define the XEPHYR_DRI macro.
define it when --enable-xephyr and --enable-dri are both turned on.
* hw/kdrive/ephyr/XF86dri.c: copy this from mesa source to enable
Xephyr to talk DRI protocol the host X. In mesa, this is used by libGL.so to
talk DRI protocol with the server.
* hw/kdrive/ephyr/ephyr.c: finally initialise the DRI extension
in the ephyrInitScreen() function.
* hw/kdrive/ephyr/ephyrdri.c,ephyrdriext.c: safeguard the compilation
using the XEPHYR_DRI macro.
* dix/events.c, include/dix.h:
(UpdateSpriteForScreen): added this to update the mouse sprite context
when we switch from a pScreen to another.
* mi/mipointer.c:
(miPointerWarpCursor): as we are switching to a new pScreen,
don't forget to update the mouse sprite context.
Let the drivers only generate XI events and put those into the event queue.
When processing events, generate core events as needed. This fixes a number of
problems with XKB and the DIX in general.
The previous approach was to put core events and XI events as separate events
into the event queue. When being processed, the server had no knowledge of
them coming from the same device state change. Anything that would then change
the state of the device accordingly was in danger of changing it twice,
leading to some funny (i.e. not funny at all) results.
Emulating core events while processing XI events fixes this, there is only one
path that actually changes the device state now. Although we have to be
careful when replaying events from synced devices, otherwise we may lose
events.
Note: XI has precedence over core for passive grabs, but core events are
delivered to the client first.
This removes the wrapping added in 340911d724
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
XI events can now take the same processing paths as core events, and should do
the correct state changes etc.

Add keyc->postdown, which represents the key state as of the last mieqEnqueue
call, and use it when we need to know the posted state, instead of the
processed state (keyc->down). Add small functions to getevents.c to query and
modify key state in postdown and use them all through, eliminating previously
broken uses.
Using a global array for action filters is bad. If two keyboard hit a modifier
at the same time, releaseing the first one will deactivate the filter and
thus the second keyboard can never release the modifier again.
Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
We shouldn't be able to restrict events like Expose, etc. with device based
ACLs. So we just ignore all non-input events when checking for permissions.
The pixman headers have been located under pixman-1/ instead of pixman/ since
around 2007-08-06, and pixman-1.pc has the updated include paths to account
for this.
This reverts commit feb1b3e455.
A passive core grab doesn't specify the device, and is thus created with the
ClientPointer as device. When this grab is activated later, don't actually
activate the grab on the grab device, but rather change the device to the one
that caused the grab to activate. Same procedure for keyboards.
Makes core apps _A LOT_ more useable and reduces the need to set the
ClientPointer.
Only applies to core grabs!
Add support for HAL-based hotplugging, in which we just get the list of
input devices and properties from HAL. Requires an FDI which is not yet
in mainline HAL.
Break up D-Bus into two components: a D-Bus core that can be used by any
part of the server (for the moment, just the D-Bus hotplug API, and the
forthcoming HAL hotplug API), and the old D-Bus hotplug API.
