Summary:                    [patch] Crash in res_agi when trying to send
application usage
Description: 
I believe this bug is related to the fact that my console documentation is
not loaded (see bug https://issues.asterisk.org/view.php?id=16688).

When sending an invalid AGI command to Asterisk, the system attempts to
return usage information for the requested application.  Based on my
reading of the crash information from gdb, because the console
documentation is not loaded, the usage information is not available
(c->usage is uninitialized).  On my system, this causes a segfault when it
is referenced.

I have attached output from gdb (bt; bt full; thread apply all bt full).

Tilghman: It looks like there is a typo in your patch at res/res_agi.c near
line 1006.  AST_LIST_LOCK() was changed to ST_LIST_LOCK().

I'm applying your patch to my system and will test it over the next few
days.
