Log Message:
Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to
DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic.  Intended
for machines where debug on panic is useful, but DDB entry is not,
(public-access console, or terminal-servers which send spurious breaks)

Add new ddb hook, console_debugger(), which decides whether or not to
ignore console ddb requests. Console drivers should be updated to call
console_debugger(), not Debugger(), in response to serial-console
break or ddb keyboard sequence.
