0.563: YAAAR.

Move more release code from Makefile to CL.
Fix shell-tokens-to-Makefile on CLISP (CLISP bug in loop, or my misreading the spec?)
Fix some tests, make them more verbose.
Driver: Fix native-namestring on SCL; fix issues on CLISP:
Setting the *source-file-types* and *compiled-file-types* to nil
was preventing (require "linux") from working(!).
