"I've noticed that we can remove particular extension from context with
dialplan remove extension command but in order to remove all extensions
in the context we should delete them on by one. I've created dialplan
remove context command which uses ast_context_destroy to destroy the
whole context with all extensions. I've created to functions for in
pbx_config.c: handle_cli_dialplan_remove_context which actually removes
context and complete_dialplan_remove_context which completes input.
They are based on other similar functions and pretty trivial but I can be
mistaken somewhere.
"I've also modified dialplan add include <context2> into <context1>. I've
made it similar dialplan add extension ... command. It creates <context1>
if it doesn't exist and I've also modified complete_dialplan_add_include
and removed check for existance of <context2> because we can include
non-existent context into another one. (I usually include empty
(non-existent) contexts in advance). Should we raise warning in this case
as it's raised while reading extensions.conf?
"I use those functions with AMI. I think manager commands should be created
in addition to those CLI commands."
I've addressed the latest comments on review board and have made some other
coding guidelines-related cleanup. I also have modified the CHANGES file to
mention these new commands.

CLI
-------------------
+ * The "dialplan add include" command has been modified to create context a context
+ if one does not already exist. For instance, "dialplan add include foo into bar"
+ will create context "bar" if it does not already exist.
+
+ * A "dialplan remove context" command has been added to remove a context from
+ the dialplan
+
* The "mixmonitor list <channel>" command will now show MixMonitor ID, and the
filenames of all running mixmonitors on a channel.
