This patch defines the basics of a generic RPC protocol in XDR.
This is wire ABI compatible with the original remote_protocol.x.
It takes everything except for the RPC calls / events from that
protocol
- The basic header virNetMessageHeader (aka remote_message_header)
- The error object virNetMessageError (aka remote_error)
- Two dummy objects virNetMessageDomain & virNetMessageNetwork
sadly needed to keep virNetMessageError ABI compatible with
the old remote_error
The RPC protocol supports method calls, async events and
bidirectional data streams as before
* src/Makefile.am: Add rules for generating RPC code from
protocol & define a new libvirt-net-rpc.la helper library
* src/rpc/virnetprotocol.x: New generic RPC protocol
