Changes to create an IO_START AST that perfoms initialization,
like clearing the event flag, if not an AST call, and setting up the
IOSB.

There is a bunch of output still being generated routine, but once the
code is working I'll start clearing that up.
Moved the NETLIB_BUILD definition around to avoid duplicate definitions of
the SSL routines.
Updated to correctly convert files generated from SDL so they will
correctly store in git after being regenerated.
Further fixes to the use of $waitfr.  Now looking at AST handling...

Still lots of output...
