VTY: implement talloc context introspection command
This change introduces a new command, which could be used to
inspect the application's talloc context directly from VTY.
To enable this feature, an application need to provide it's
context via the 'vty_app_info' struct, and register the VTY
command by calling the osmo_talloc_vty_add_cmds().
The new command is a sub-command of 'show':
show talloc-context <context> <depth> [filter]
Currently the following contexts may be inspected:
- application - a context provided by an application;
- null - all contexts, if NULL-context tracking is enabled.
A report depth is defined by the next parameter, and could be:
- full - full tree report, as the talloc_report_full() does;
- brief - brief tree report, as the talloc_report() does;
- DEPTH - user defined maximal report depth.
Also, there are two optional report filters:
- regexp - print only contexts, matching a regular expression;
- tree - print a specific context, pointed by specified address.
The command output is formatted the same way as in case of calling
the talloc_report() or talloc_report_full().
