This is intended to be used by screen lockers, where the server must
exit if the screen locker does, to avoid a security hole. As suggested
by Alan Coopersmith, this is implemented using a new flag for the
disconnect mode of the XFixes extension. Includes wording suggestions
from Peter Hutterer.

The Xserver itself is capable of terminating itself once all X11 clients
are gone, yet in a typical full session, there are a number of X11
clients running continuously (e.g. the Xsettings daemon, IBus, etc.).
Those always-running clients will prevent the Xserver from terminating,
because the actual number of X11 clients will never drop to 0.
To solve this issue directly at the Xserver level, this add new entries
to the XFixes extension to let the X11 clients themselves specify the
disconnect mode they expect.
Typically, those X11 daemon clients would specify the disconnect mode
XFixesClientDisconnectFlagTerminate to let the Xserver know that they
should not be accounted for when checking the remaining clients prior
to terminate.

In the implementation of HideCursor/ShowCursor in the xserver code,
the window passed in only identifies a screen, not a portion of the
window tree, and it's been that way since the beginning. Changing
the implementation at this point would likely break existing code,
and the main usage of this protocol (magnifiers) only needs the
global behavior, so change the protocol to document the actual
behavior.

Technically this is a change in the protocol, but we've never supported
anything but a Window.

CursorNotifies are only sent for the ClientPointer to avoid confusion in the
client.

Servers supporting XI2 will hide all cursors when a client requests
HideCursor. This is arguably closest to the original intent of the request -
to not display a cursor above the given window.

The semantics in the spec were conflicting, and the implementation did the
'don't remap' version which was not useful. The server implementation has
been fixed, this change clarifies the specification to match that design.
