It's useful to know this value.
W/o cache (first pre-dump) on minimal container the irmap
resolve time is ~0.2 sec. With cache (next pre-dumps or
final dump) on the same container the irmap resolve time
is 10 times less.

We really have a mess of extern/non-extern declaration
of functions in our headers. Always use extern for
unification purpose.

For big #ifdef/#endif chunks we do a comment /* */
at #endif. Add missing ones.

We have generic do_pb_show() call and tons of show_foo
routines, that just call one with proper args. Compact
the code by putting the args into array and calling
the do_pb_show() in one place.

This will only work if timiings are reported by a single
task. Collecting them from several tasks is to be done.

On restore we compare pages' contents with memcmp to check which
of them can remain shared. Report this info in restore stats.

Restore stats are difficult -- we have to collect them from several
tasks and thus existing plain variables would not work. We'll need
shared memory with stats, so prepre for allocating one.
Other than this -- put call to write_stats() where appropriate for
restore.

pages_scanned -- the amount of pages criu looked at for decision
pages_skipped_parent -- the amount of pages that were skipped, due to
they are present in parent image
pages_writted -- the amount of pages criu transfered into image

Dumping memory is draining it from parasite, for pre-dump
this time would be reasonably small. _Writing_ the memory
would occur _after_ tasks unseize and resume.

We'll have one more "image" file generated by dump and (surprisingly)
restore commands -- the stats one. It will contain in a single pb
object all the statistics collected by dump/restore.
