Subject: dynamic-debug-howto: fix optional/omitted ending line number to be LARGE instead of 0

line-range is supposed to treat "1-" as "1-endoffile", so
handle the special case by setting last_lineno to UINT_MAX.

Fixes this error:

dynamic_debug:ddebug_parse_query: last-line:0 < 1st-line:1
dynamic_debug:ddebug_exec_query: query parse failed
