Frank Halasz 40a1a8dcd2 Rationalize the processing of command line args for the sysout. Fixes Issue#1703 (#503) 
* Rationalize the processing of command line args for the sysout.  Remove most of the redundancy between what is done for sysout arg processing in xrdopt.c versus main.c.  Move all of the decision making about what sysout_name to use until all args have been processed (both in xrdpopt and main).  This is done in main, where the prioritization and checking is done in one place rather than spread in several places in xrdopt and main.     //  Order of priority:
628   //    1. Value of -sysout command line arg
629   //    2. Value of the first command line arg
630   //    3. Value of LDESRCESYSOUT env variable
631   //    4. Value of LDESOURCESYSOUT env variable
632   //    5. Value as determined by X resource manager, if any
633   //    6. Value of /home/frank/lisp.virtualmem (or lisp.vm for DOS)

* In main.c moved check for sysout as first arg to before the call to read_Xoption.  This will ensure that we always check the 'true' first argument even when read_Xoption modifies argv.
