SRFI-1: Rewrite break' and break!' in Scheme.

Browse source 
This partially reverts commit 6e9f3c2676
(Tue May 3 2005).

* module/srfi/srfi-1.scm (break, break!): New procedures.

* srfi/srfi-1.c (scm_srfi1_break, scm_srfi1_break_x): Rewrite as
  proxies to the corresponding Scheme procedures.

* test-suite/standalone/test-srfi-1.c (failure): New function.
  (tests): Add `scm_srfi1_break' test.  Use `failure'.
