* TESTUPF: Move from internal/ to internal/test/unpackfilename
to be parallel with filepos
* IOCHAR: FILEPOS respects external format (#3)
* FILEPKG: EDITCALLERS speed up with new FILEPOS
* internal/test/filepos: Testing jig and cases for new FILEPOS
* EXTERNALFORMAT, IOCHAR: fix external-format glitches
* IOCHAR: Fix daylight savings time
* TMAX: Y2K fix
Also a little code cleanup, changing default font to TERMINAL from GACHA and making text more legible
* DATABASEFNS, ATBL: DUMPDB with DEFINE-FILE-INFO
New database files will have standard headers, then a little special stuff for LOADDB to synchronize, old database files default to a new interlisp environment.
MAKE-READER-ENVIRONMENT in ATBL extended for easier specification, plus better type-testing.
* Remove duplicate comment
