Summary:                    [patch] Asterisk segfaults while doing a 'module
reload'.
Description: 
While doing a 'module reload res_features.so' asterisk crash.
Also while doing a 'module unload res_features.so' and then a 'dialplan
show parkedcalls'

I have found that the crash while doing 'module unload res_features.so' is
because while doing a ast_context_create() the registrar parameter is
static memory and while doing a module unload we lost the reference.
The problem can be solved destroying every created context while doing a
module unload like I have done with res_features.c but we have the same
problem with other modules like app_dial, etc, every module that creates a
context and doesn't destroy it while unloading.
To solve the crash I make a copy of the 'registrar' to prevent this
conditions, or we could leave the registrar as is, and check every
app/res/pbx/etc that creates a context and put code to destroy it while
unloading.
