Summary:                    [patch] Huge memory leak
Description: 
I detected a memory leak on all my Asterisk servers. 

After 1 day, Asterisk is using 100+ meg.

I recompiled with MALLOC_DEBUG on DONT_OPTIMIZE. 
See dump of memory summary and memory allocations.

Fix a memory leak in pbx_spool when using SetVar in a call file.

In pbx_spool, when we are freeing our 'outgoing' struct, we weren't
deallocating
the ast_variable list we had built from SetVars in a call file.  Adding a
call to
ast_variables_destroy in our deallocation routine works, but only if the
variables
have not already been passed into ast_pbx_outgoing_app() or _exten(), both
of
which take care of destroying the variable list for us.
