Add optional UID to DISPLAY() in chansrvport

Browse Source 
The code to determine the socket address of chansrv when using
a manually started xrdp-chansrv may need some help determining
the UID of the session.

This commit allows a UID to be optionally specified in the
DISPLAY() function, if the code is unable to determine the
UID automatically from the connection parameters.

If a manual chansrvport is entered, xrdp now logs what it is
connecting to, to assist in debugging.

This can be useful if you wish to use to use xrdp to connect to a VNC session
which has been started other than by \fBxrdp-sesman\fR, as you can then make
use of \fBxrdp\-chansrv\fR facilities in the VNC session.

Either the first or second form of this setting is recommended. Replace
\fIn\fR with the X11 display number of the session, and (if applicable)
\fIu\fR with the numeric ID of the session. The second form is only
required if \fBxrdp\fR is unable to determine the session uid from the
other values in the connection block.
