There's only two reasons for hierarchy events:
- device is added, removed, etc. In this case we want to send the event as
it happens.
- devices are added in a XIChangeDeviceHierarchy request. In this case we
only want one event cumulating all changes.
Rather than have one field per hierarchy change, XI2 has two fields - one
generic one and one per-device that include the device-specific flags.
This requires some funky handling for removed devices, but oh well.
Reproducible:
Configure a server that uses the keyboard driver with an invalid ruleset,
e.g. (Option "XkbRules" "foobar"). Ensure that Option "AllowEmptyInput" is
"off" in the ServerFlags or ServerLayout section. Start the server.
After failing to init the keymap, the server will try to clean up after the
device, double-freeing some xkb structs that have not been reset properly.

Xephyr doesn't manually set Activate/DeactivateGrab for new devices,
resulting in a NULL-pointer dereference later when a grab is activated.
Avoid the segfault by ensuring that the pointer is always valid.

This function was deprecated in ef68273f5b
because it didn't take a device argument. The device argument was added in
1c7568b8a1 though, so the deprecation is
obsolete.

This way clients querying the gamma value via the VidMode extension at least
get the last value set via the same, rather than always something bogus.

newer gcc's warn against how this cast is done (though it eludes me why),
and lrintf() is also faster especially on insane processors like the P4

This is a shorthand for disabling acceleration, while retaining the
possiblity to use constant deceleration. If constant deceleration is
also unused, it will optimize motion processing.
Other possiblities to deactivate acceleration were quite hidden,
and didn't always work as expected. E.g. xset m 1 1 would retain
adaptive deceleration, while xset m 1 0 would not (in the default
profile).
Also removes the 'reserved' profile; it was unused and it's trivial
to add new ones anyway.
