Aaron Plattner c80c41767e os: Fix BigReq ignoring when another request is pending 
Commit cf88363db0 fixed the handling of
BigReq requests that are way too large and handles the case where the
read() syscall returns a short read.  However, it neglected to handle
the case where it returns a long read, which happens when the client
has another request in the queue after the bogus large one.

Handle the long read case by subtracting the smaller of 'needed' and
'gotnow' from oci->ignoreBytes.  If needed < gotnow, simply subtract
the two, leaving gotnow equal to the number of extra bytes read.
Since the code immediately following the (oci->ignoreBytes > 0) block
tries to handle the next request, advance oci->bufptr immediately
instead of setting oci->lenLastReq and letting the next call to
ReadRequestFromClient do it.

Fixes the XTS pChangeKeyboardMapping-3 test.

					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:
