Respect *DEBUG-PRINT-VARIABLE-ALIST* when printing args in PRINT-FRAME-CALL

PRINT-FRAME-CALL used to bind *PRINT-LENGTH* and *PRINT-LEVEL* while
printing function names and arguments. These variables are now only
bound while printing function names to
allow *DEBUG-PRINT-VARIABLE-ALIST* control over printing arguments.

Fixes lp#1261646.
Give CLEAR-INFO unsurprising behavior in a dumped & restored core.

This fixes a bug mentioned in email to sbcl-devel ca. 9/11/2013
("Globaldb screwyness because of purify").
