Description: Fix Guile deprecation mesages; modify guile module testsuite for Guile 2.x
 * modules/guile/guile.c (guile_safe_exec) (guile_call_proc): Use
   scm_c_with_throw_handler for Guile 2.0 and newer.
 * examples/listdict.scm: (ice-9 syncase) no longer needed.
 * include/testsuite.inc (DICOD_RUN): Take stderr filter as an optional second
   argument.
 * modules/guile/tests/define.at: Filter out Guile compiler messages from
   stderr.
 * modules/guile/tests/exact.at: Likewise.
 * modules/guile/tests/lev.at: Likewise.
 * modules/guile/tests/prefix.at: Likewise.
 * modules/guile/tests/showdb.at: Likewise.
 * modules/guile/tests/showinfo.at: Likewise.
 * modules/guile/tests/showlang.at: Likewise.
 * modules/guile/tests/suffix.at: Likewise.
