Matthew D Fleming 3a5d36716f Modify kdb_trap() so that it re-calls the dbbe_trap function as long as ... the debugger back-end has changed. This means that switching from ddb to gdb no longer requires a "step" which can be dangerous on an already-crashed kernel. Also add a capability to get from the gdb back-end back to ddb, by typing ^C in the console window. While here, simplify kdb_sysctl_available() by using sbuf_new_for_sysctl(), and use strlcpy() instead of strncpy() since the strlcpy semantic is desired.
