[RFA/testsuite] New 'until' tests


I added files until.c and until.exp that include the only 'until'
tests that the testsuite had (from break.exp) plus a couple of new ones.

OK?

2002-12-20  Elena Zannoni  <ezannoni@redhat.com>

	* gdb.base/break.exp: Move the tests of until command from here...
	* gdb.base/until.exp: ... to here. New file. Add other tests.
	* gdb.base/until.c: New file.
