Xlib.h: Fix macros imitating C functions.

Browse source 
The basic rule "put parantheses around macro parameters" should be
observed where possible. Otherwise code like

    ConnectionNumber(foo = bar);

fails to compile. (It obviously passes if ConnectionNumber is a C
function.) There are several other macros amended for the same reason.

This bug appeared while building http://ioccc.org/1993/cmills.c, so
historically it was not present.
