dynamic_debug: add modname arg to exec_query callchain
Pass module name into ddebug_exec_queries(), ddebug_exec_query(), and
ddebug_parse_query() as separate parameter. In ddebug_parse_query(),
the module name is added into the query struct before the query-string
is parsed. This allows the query-string to be shorter:
instead of:
$modname.dyndbg="module $modname +fp"
do this:
$modname.dyndbg="+fp"
Omitting "module $modname" from the query string is actually required
for $modname.dyndbg rules; the set-only-once check added in a previous
patch will throw an error if its added again. ddebug_query="..." has
no $modname associated with it, so the query string may include it.
This also fixes redundant "module $modname" otherwise needed to handle
multiple queries per string:
$modname.dyndbg="func foo +fp; func bar +fp"
