This patch add a stats.schedmiss.* set of entries that
are a record of the last 10 times corosync was not scheduled
in time.
These entries are keypt in reverse order (so stats.schedmiss.0.* is
always the latest one kept) and the values, including the timestamp,
are in milliseconds.
It's also possible to use a cmap tracker to follow these events, which
might be useful.

When cmap_track_delete was called to stats map (cmap created with
CMAP_MAP_STATS parameter) result was always ERR_BAD_HANDLE.
It turned out that corosync part of cmap is always calling icmap
function to get user data (where required hdb handle is stored)
instead of generalized map_fns.
After fixing this issue, valgrind showed error about jump depending on
unitialized data in stats_map_track_delete. Solution seems to be always
initialize tracker->events (so not only when track_type is add or
delete).

Only add the knet handle stat keys if we are actually running knet. This
prevents errors occurring when iterating through all of the stats keys

knet handle stats show compression and crypto statistics. With these
you can see the effectiveness of compression and the overheads of both
crypto and compression.

Icmap is factored out so it's possible to add other
maps for cmap. API call to switch maps from application
end is added.
Corosync-cmapctl is enhanced with -m option.
Stats contains all statistics previously found in runtime.connections,
runtime.services and runtime.totem prefixes together with new knet
related. All stats are read only.
