Add a new DDB(4) facility, output capture. Input and output from DDB may be
captured to a memory buffer for later inspection using sysctl(8), or in the
future, to a textdump.
A new DDB command, "capture", is added, which accepts arguments "on", "off",
"reset", and "status".
A new DDB sysctl tree, debug.ddb.capture, is added, which can be used to
resize the capture buffer and extract buffer contents.
