Aaron Plattner 3ea7d271c8 os: Return BadLength instead of disconnecting BigReq clients (#4565) 
If a client sends a big request that's too big (i.e. bigger than
maxBigRequestSize << 2 bytes), the server just disconnects it.  This makes the
client receive SIGPIPE the next time it tries to send something.

The X Test Suite sends requests that are too big when the test specifies the
TOO_LONG test type.  When the client receives SIGPIPE, XTS marks it as
UNRESOLVED, which counts as a failure.

Instead, remember how long the request is supposed to be and then return that
size.  Dispatch() checks the length and sends BadLength to the client.  Then,
whenever oci->ignoreBytes is nonzero, ignore the data read instead of trying to
process it as a request.

					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:
