This types specifies a strict set of what is hidden behind
the fd. Thus these numbers should be in the description of
the fdinfo message.
Plus protobuf makes shure nothing else will be there.

We've switched to SkOptsEntry, no need to carry this
obsolete one.

We are ready to use FownEntry everywhere,
so drop fown_t type and clean up source code.

A short story -- there were a long conversation on which format should
be used to keep checkpointed data on disk image. We ended up in using
Google's Protocol Buffers (see https://developers.google.com/protocol-buffers/
for detailed description). Thus image entries should be convered to PB.
This patch converts fdinfo_entry to PB "message fdinfo_entry".
Build note: one should have protobuf and protobuf-c installed to be able
to build crtools.

We will need to use pointer here (to PB object) anyway
so better to make it in a separate patch for bisectability sake.

Use fdtype_ops facility to c/r unix sockets.
v2
- BUG_ON added in dump_one_unix_fd if socket
is already dumped since we never should dump
same socket several times
- The order of restore remains as it was before,
the lookup is done via socket inode numbers

The task is not complete - this is just a part of what have to be done. I.e.
looks like a lot of excessive deps can be fixed.

While been playing with sockets dumping I found a case where
we exit without descriptive error message. Fix it.

Those sitting on the SOL_SOCKET level are common to different
socket families and will be handled in a generic code.

This saves some space on dynamic file_desc and makes file_desc_ops
looks closer to fdinfo_ops used on dump.

Funny, but after this git thinks, that I've renamed the sockets.c
file into sk-unix.c one and fixed it a little bit %)
