/*
* sup "meat" routines
**********************************************************************
* HISTORY
*
* 7-July-93 Nate Williams at Montana State University
* Modified SUP to use gzip based compression when sending files
* across the network to save BandWidth
*
* 10-Feb-88 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added timeout to backoff.
*
* 27-Dec-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added crosspatch support.
*
* 09-Sep-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added code to be less verbose when updating files that have
* already been successfully upgraded.
*
* 28-Jun-87 Glenn Marcy (gm0w) at Carnegie-Mellon University
* Added code for "release" support.
*
* 26-May-87 Doug Philips (dwp) at Carnegie-Mellon University
* Converted to end connection with more information.
* Added done routine. Modified goaway routine to free old
* goawayreason.
*
* 26-May-87 Doug Philips (dwp) at Carnegie-Mellon University
* Use computeBackoff from scm instead of doing it ourselves.
*
* 25-May-87 Doug Philips (dwp) at Carnegie-Mellon University
* Split off from sup.c and reindented goaway calls.
