* Fix to Issue#1022 Error during greet
* More fix to Issue#1022. Turns out need to reset MEDLEYDIR for AFTERMAKESYS as well as at greet time. Discovered during loadup-online.sh with no greet file.
* Removing AFTERMAKESYS event action from (MEDLEY-INIT-VARS). Cleaning up a bit the GREET event action in (MEDLEY-INIT-VARS). Remove issue with MEDLEY-INIT-VARS being called after the user greet file in the AFTERMAKESYS case.
This corrects some errors in the handling of initializing variables across SAVEVM, LOGOUT, SYSOUT and MAKESYS.
This is all now handled by MEDLEY-INIT-VARS (function and variable) which is called as an EVENTFN.
BEFOREMAKESYS (invoked by ENDLOADUP) clears the variables to a default setting (all directories are just {DSK}).
The other "BEFORE" events save away the current values of the variables in MEDLEY-INIT-VARS.
In order to get this to work it was necessary to change a hack for deciding where to find EXPORTS.ALL and WHEREIS.HASH. Now if you do `./scripts/loadup-all.sh` to make a full, lisp sysouts, exports.all and whereis.hash it will still build the sysouts in tmp/ but will also "link" new versions in loadups (and library for exports.all). This replaces the previous hack scanning the sysout name for "tmp/".
MEDLEY-INIT-VARS had been called both by the AROUNDEXITFN and AFTER*FORMS.
* Rework MEDLEYDIR before/after logout to substitute instead of reset
* debugging
* working when changing home directory
* fix bug and removed redundtant declarations
* TEDIT files: deleted from library/, renamed to library>tedit.TEDIT-xxx
* PSEUDOHOSTS: Error if file won't open
* LOADUP-*, MEDLEYDIR, UNICODE
Adjustment for TEDIT-xxx, plus moving UNICODE to the beginning of LOADUP-LISP, with UNICODEDIRECTORIES creating in MEDLEYDIR
* Start loadup using lisp.venuesysout as the base on which to build new
* Change 'starter.sysout' (taken from recent lisp.sysout)
* Fix problem with GREET ordering
