Subject: ui: Auto-compile user code, and improve error reporting.

Reported by Christian Grothoff.

* guix/ui.scm (load*): Add 'frame-with-source'.  Set
  %load-should-auto-compile.  Change error handle to just (exit 1).  Add
  pre-unwind handler to capture the stack and call 'report-load-error'.
  (report-load-error): Add optional 'frame' parameter and pass it to
  'display-error'.
* tests/guix-system.sh: Add "unbound variable" test.
