[Asterisk-code-review] Fix potential crash after unload of func periodic hook or te... (asterisk[13])

[Corey Farrell]

Corey Farrell has uploaded a new patch set (#2).

Change subject: Fix potential crash after unload of func_periodic_hook or test_message.
......................................................................

Fix potential crash after unload of func_periodic_hook or test_message.

These modules save a pointer to the context they create on load, and
use that pointer to destroy the context at unload.  It is not safe
to save this pointer, it is replaced during load of pbx_config,
pbx_lua or pbx_ael.

This change causes the modules to pass NULL to ast_context_destroy,
a safer way to perform the unregistration since it does not use
a pointer that could become invalid.
