Lets use one default log filename. User can set if in request, if needed.

Lets rename CriuDumpReq to CriuOpts, for the sake of readability and to
avoid coping code for restore mechanism, as CriuDumpReq and
CriuRestoreResp would have almost the same fields. Also, it would be
easier to introduce other types of requests.

Right now we have an ability to launch the C/R service from root
and execure dump requests from unpriviledged users. Not to be bad
guys, we deny dumping tasks belonging to user, that cannot be
"watched" (traced, read /proc, etc.) by the dumper.
In the future we will use this "engine" when launched with suid
bit, and (probably) will have more sophisticated policy.

I don't know a reason, when accept() fails once and then goes back to
normal work.

When service/page server becomes daemon, we may need to know it's pid.

Now we don't have generic criu_msg thing -- instead, we have
explicit request (with per-type args) and explicit responce
(yet again -- with per-type args).

The most of fields are to be changed to "optional", because they are
optional in fact.

The criu service is a daemon, that opens a unix socket and listens for
incoming requests. The requests will be declared in protobuf/rpc.proto
and for now will only contain the 'dump' request.
