Disclaimer: It's 6:51am. I'm trying to be as understandable as possible.
What was happening previously was this:
* Press Alt
* Extended event generated and processed: state is now Alt down once
* Core event generated
- keyboard switched: inherited state is Alt down once
- event processed: Alt down twice
* Release Alt
* Extended event generated and processed: state is now null
* Core event generated and processed: Alt down once
If we switch the order:
* Press Alt
* Core event generated:
- keyboard switched: inherited state is null
- event processed: Alt down once
* Extended event generated and processed: state is now Alt down once
* Release Alt
* Core event generated and processed: state is now null
* Extended event generated and processed: state is now null
When we carry over the previous state, it needs to be the _previous_ state
(state and modifiersPerKey), assuming that we're going to catch now-core
events for any of these. For example, if Ctrl is held down as we pivot, we
need to carry Ctrl over with a count of one, for which an extended + core
release will then clear. Carrying over the union of the previous state _and
the state resulting from the immediate action_ was what broke things.
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.
For some reason, my keyboard has 25 mouse buttons, but zero valuators. This
causes GPE to blow up spectacularly, trying to get (and set) co-ordinates from
devices without valuators. For now, just prevent this from ever happening,
and whack a dirty great FIXME in.
Make sure the font path is always 'built-ins' when we use built-in fonts,
rather than having it as a fixed path for a while, then clobbering it
halfway through startup.
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.
This patch changes the semantics of manual redirect windows so that they no
longer affect the clip list of their parent. Doing this means the parent can
draw to the area covered by the child without using IncludeInferiors. More
importantly, this also means that the parent receives expose events when
that region is damaged by other actions.
DeletePassiveGrabFromList() may remove the window optional, so we need to
re-alloc it if it isn't there anymore.
Thanks to Colin Harrison for spotting the bug.
Device drivers flush their buttons on device init and cause a button down
event to be generated. If we unconditionally decrease the buttons, we won't be
able to ever get a passive device grab.
Format documentation for CheckDeviceGrabs to make it readable.

Conflicts:
Xi/exevents.c
Before you complain, this code hasn't seen material change since at least
X11R6. It certainly does not build with any modern version of Kerberos.
Anybody wanting krb5 auth to their X server should probably be using
GSSAPI instead of internal krb5 API anyway.
Make core events carry the same modifier state as the extended events, so
that holding down Ctrl on keyboard A and pressing Q on keyboard B won't
cause your app to quit.
The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
include/xkbsrv.h, and the world updated to look for it in the new place,
since it made no sense to define server API in an extension header. Any
further work along this line will need to do similar things with XKBgeom.h
and friends.
Always chase a DeviceMotionNotify event with a DeviceValuator, which is
not required in the spec, but will silently break the lib if you don't
include.
automake will not stop whining about the *.O files not being in normal library
name format, so just tell automake they are PROGRAMS so it builds them without
bitching.
Handle an argument of 0 in ffs(), instead of looping indefinitely.
Add an ffs prototype to dix.h, and add includes to ffs.c.
(cherry picked from 34164e551e4c3909322d50b09835ca4ac1d49d68 commit)
Fix up prototypes for PrintChildren and PrintWindowTree in the dix.
Make miPrintRegion be unconditionally defined, and move the prototype into
regionstr.h.
Change a bunch of ScreenPtr pScreen = foo; to
ScreenPtr pScreen; pScreen = foo; in window.c, so we avoid unused variable
references (as inline REGION_* doesn't reference pScreen).
With Xinerama support built into the X server but not in use,
sprite.screen is NULL and yet the SyntheticMotion
macro would dereference it. Avoid that by just passing sprite.screen
to PostSyntheticMotion which can then dereference it when Xinerama is
enabled.
Also, define PostSyntheticMotion in dixevents.h and include dixevents.h in
getevents.c
Add a generic 'ring the bell' function (console bell on Linux and BSD,
/dev/audio on Solaris), and add DDX functions for this. Make this the
core keyboard's bell.
Port Xvfb and Xnest to this.
Port XFree86 to this, with OS-specific hooks for Linux, BSD, and Solaris
taken from foo_io.c in the old layer.
Remove keymap copy from GetKeyboardValuatorEvents, as
SwitchCoreKeyboard now takes care of this for us.
Remove unused variable and function prototype.
Update comments to be as informative as possible.
Update the DEVICE_ABS_CALIB stuff to include the new elements.
New DEVICE_ABS_AREA support.
dev->touchscreen becomes dev->absolute, with _CALIB and _AREA stuff in it.
Update xfree86 to compile with this, kdrive needs an update too.
Move the keymap copying to event processing time (in
ProcessInputEvents), instead of being at event enqueuing time.
Break SetCore{Pointer,Keyboard} out into separate functions.
Change mieqEnqueue to take a device pointer, that asks for the
_original_ device associated with this event.
Add devices in forward order with the normal linked list convention.
Previously, AddInputDevice would add all the devices in reverse order to
off_devices, before they were added again in reverse order to devices with
EnableDevice.
This just makes both work in forward order, which provides the ordering as
you'd expect when hotplugging devices (i.e. adds them to the head, not the
tail).
