stats/vty: Add stats_vty.c

This file will contain the VTY code related to statistics.

This commit adds a minimal file with just as single VTY command:

- show stats This command shows all statistical values

To enable this and future commands, the main program needs to call stats_vty_add_cmds().

stat/vty: Use the iterator algorithms to show ctrg and statg

Currently the groups for stat_items and counter are iterated manually.

This commit makes use of the new iterator functions to access the single elements via handlers.

commit 02906e0f1cfb1a4fb782c3badd7f598d57fab86c Author: Jacob Erlbeck jerlbeck@sysmocom.de Date: Mon Oct 19 13:45:42 2015 +0200

core: Extend rate_ctr by helper functions

For global value reporting, some additional helper functions are needed. The statsd protocol expects differential counter values, which are currently not provided by rate_ctr (except for s/m/h/d intervals).

This commit adds several helper functions to rate_ctr:

- rate_ctr_difference returns the counter delta since the last call to this function for a given counter - rate_ctr_for_each_counter iterates through each counter of a group - rate_ctr_for_each_group iterates through all globally registered counter groups

Note that the rate_ctr_difference function can only be used by a single backend, since it modifies the 'previous' field in the rate_ctr obj.
