Some files (notably those merged with MPX before XI2 came along) didn't use
a 'xi' prefix. This patch changes all of them to meaningful names.

If SetClientPointer fails, the only reason may be that the device is not a
pointer or that the device is an SD. Return BadDevice instead of BadAccess.
(BadAccess is a leftover from the early times of the ClientPointer
implementation when only one client was allowed to set it).
If the window parameter doesn't name a valid window or client, return
BadWindow.
Finally, allow both master keyboards and master pointers as deviceid.

This was quite old code and can be streamlined a bit. The new code is
essentially the same as in ProcXISetClientPointer.

Swapping the mask_len and then advancing the pointer by the swapped length
is just a bad idea.

The maximum number of bytes is calculated by the mask len, and the mask len
is always in 4-byte units. XI2MASKSIZE however is in bytes.

zero-length masks are supposed to clear the device's mask.
ProcXISelectEvents passes these masks through directly, so we need to clear
the bits here if such a mask is supplied.

The data is already swapped before, so we just post it to the client as-is,
without attempting to swap it again.

inputstr includes XI2proto.h for the sole purpose of XI_LASTEVENT.
However, using XI_LASTEVENT in the server is prone to errors, if the server
is recompiled against a newer version of the protocol it would bump this
variable and associates bits, including potential ABI.
This patch defines an XI2LASTEVENT for use in the server and removes the
XI2proto.h require. XI2LASTEVENT is the current value of XI_LASTEVENT.
This patch is required by components that require access to inputInfo
(currently xf86-video-geode and xf86-video-cirrus) but should not have a
require for the XI2 protocol.

Two issues that combined to false positives and false negatives.
- The checking for invalid bits must be performed when there are enough bits
that an event outside of LASTEVENT may be selected.
- The first invalid bit is LASTEVENT + 1, not LASTEVENT.

The protocol allows for 16 bit device ids, but the implementation doesn't
yet. We need to break the input ABI once more to shift the DeviceIntRec's
CARD8 to a CARD16, along with some changes in the privates.
Once that is done, revert this patch.

The server returned the minimum of major/minor each instead of the lower of
the combined major.minor version. As a result, a client reporting
3.0 and a server supporting 2.7, the return value would be 2.0 (the minimum
of both).

XIQueryVersion must return the client's version if the client's version is
lower than or equal to the server's version, or the server's version
otherwise.

86077f0058ce88ee9b3df5d1ab854eeca43 switched from a boolean to a grabtype
enum. ProcXGrabDevice didn't switch with it. PickPointer during an XI grab
on a slave device would thus return a wrong (or NULL) device and crash the
server.

These grabs are suported through two fake devices inputInfo.all_devices and
inputInfo.all_master_devices. These devices are not part of the device list
and are only initialised for their device id, nothing else.

If a passive enter or focus in grab activates, send additional enter or
focus events with mode XIPassiveGrabNotify to the grabbing client.
Likewise, if the grab deactivates, send additional leave or focus out
events.

Enter grabs are checked for in CheckMotion(), each time the sprite window
changes the current grab is deactivated (if applicable) and the new grab is
activated (if applicable). Exception - if the grab is on a parent window of
the current window since we keep the grab across descendants.
Since CheckMotion() may change the grab status of a device, we mustn't get
"dev->deviceGrab.grab" in ProcessOtherEvents until after CheckMotion().
FocusIn grabs are checked in much the same manner.
The event delivery for grabs replaces the NotifyNormal on window change with
a NotifyGrab on window change. Note that this happens before the grab
activates, so the EnterNotify(NotifyGrab) is still delivered to the window,
not to the grabbing client. This is in line with the core protocol semantics
for NotifyGrab events.

Not having the resource mask set means we never match an existing grab,
hence we never actually ungrab.

In the case of a RevertToFollowKeyboard, the master device should be used
(since this is the closest equivalent to the VCK as before). Only if the
master keyboard is the same as the device, revert to the VCK itself.
This didn't use to be a problem when devices could only be pointers or
keyboards, not both. Nowadays, slave devices may have both buttons and
keyboards, and in this case we don't want to deactivate a passive keyboard
grab when a button release is detected.
The wire layout is [struct xXIEventMask][mask bytes]. So the pointer needs
to not only be advanced by the mask bytes, but also by the size of the
struct.
