Branches: main

Add a --reset-kb option to the mdb `dd' command.  The new option resets the
declarative debugger's knowledge base of previous question answers.

NEWS:
	Mention the new option.

	Move an item that was in the wrong place.

browser/declarative_debugger.m:
browser/declarative_oracle.m:
	Export a procedure to reset the oracle's knowledge base.

doc/user_guide.texi:
	Document the new option.

tests/debugger/declarative/oracle_db.exp:
tests/debugger/declarative/oracle_db.inp:
	Test the new option.

trace/mercury_trace_cmd_dd.c:
trace/mercury_trace_declarative.c:
trace/mercury_trace_declarative.h:
	Add the new option.
