This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (d4182120a4d37d5652ca304c9ea9c2b912bacd98)
\
N -- N -- N (06a64d7db2f93a996a074cfb9e1a8eacd3303eee)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

stats: Use function pointers in reporter objects
Currently case statements are used to select the right reporter
functions. This makes it difficult to add new reporter types,
especially if they are not going to reside in the same file.
This commit introduces per reporter function pointer for
open, close, send_count, and send_item. They are checked for
non-NULL before being called or skipped.

no mtu Disable multi-metric packets
Note that single messages that are longer than the given MTU (minus
28 octets protocol overhead) will be dropped.

This commit provides stats configuration similar to the log
configuration.
The following vty commands are added to the config node:
stats reporter statsd Create/Modify a statsd reporter
no stats reporter statsd Remove a statsd reporter
To actually configure a reporter, the config-stats node is entered
when the "stats reporter" command has succeeded. The following new
vty commands are available there:
local-ip ADDR Set the IP address to which we bind locally
no local-ip Do not bind to a certain IP address
remote-ip ADDR Set the remote IP address to which we connect
remote-port <1-65535> Set the remote port to which we connect
prefix PREFIX Set the item/counter name prefix
no prefix Do not use a prefix

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.

stats: Use a global index for stat item values
Currently each stat item has a separate index value which basically
counts each single value added to the item and which can be used by
a reporter to get all new values that have not been reported yet.
The drawback is, that such an index must be stored for each stat
item.
This commit introduces a global index which is incremented for each
new stat item value. This index is then stored together with the item
value. So a single stored index per reporter is sufficient to make
sure that only new values are reported.

stats: Add stat_item for value monitoring
This commit adds instrumentation function to gather measurement
and statistical values similar to counter groups.
Multiple values can be stored per item, which can be retrieved in
FIFO order. Getting values from the item does not modify its state to
allow for multiple independant backends (e.g. VTY and statd).
When a new value is set, the oldest value gets silently overwritten.
Lost values are skipped when getting values from the item.
