Michal Srb 05442de962 Xi: Zero target buffer in SProcXSendExtensionEvent.
Make sure that the xEvent eventT is initialized with zeros, the same way as
in SProcSendEvent.

Some event swapping functions do not overwrite all 32 bytes of xEvent
structure, for example XSecurityAuthorizationRevoked. Two cooperating
clients, one swapped and the other not, can send
XSecurityAuthorizationRevoked event to each other to retrieve old stack data
from X server. This can be potentialy misused to go around ASLR or
stack-protector.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
