Eric Blake 4fc55bf3b0 nbd/client: Initial support for extended headers
Update the client code to be able to send an extended request, and
parse an extended header from the server.  Note that since we reject
any structured reply with a too-large payload, we can always normalize
a valid header back into the compact form, so that the caller need not
deal with two branches of a union.  Still, until a later patch lets
the client negotiate extended headers, the code added here should not
be reached.  Note that because of the different magic numbers, it is
just as easy to trace and then tolerate a non-compliant server sending
the wrong header reply as it would be to insist that the server is
compliant.
