Now crtools checks address, but it may be zero. For example,
a listen socket is bound to zero address to accept connections
from any addresses.

There is no need in 6 receive callbacks -- we can find out family and protocol

This field was lost while switching to protobuf -- the vma images
were used by parasite as plain array and it was easier to reseve
this space in the image. Now it's too late to change this, so make

Use # for both and don't use fixed field width for 32bit one (as they are
most likely just some values, while the 64bit is some address which is better
to be printed with full width).
