Add the virt-server mode for a virtualization environment based on the listen
mode for networking. This mode works like client/server mode over TCP/UDP,
but it uses virtio-serial channel instead of IP network. Using networking for
collecting trace data of guests is generally high overhead caused
Apply trace-msg protocol for communication between a server and clients.
Currently, trace-listen(server) and trace-record -N(client) operate as follows:
server client
listen to socket fd
connect to socket fd
accept the client
Split out the connect waiting loop from do_listen() for avoiding duplicate codes
between listen mode and virt-server mode.

Add --virt option for record mode for a virtualization environment.
If we use this option on a guest, we can send trace data in low overhead.
This is because guests can send trace data to a host without copying the data
by using splice(2).
The format is:
trace-cmd record --virt -e sched*
iface in trace-listen is not used any more, so it is deleted.

Use poll(2) to wait for a message. If a client/server cannot send a message for
any reasons, the current server/client will wait in a blocking read operation.
So, we use poll(2) for avoiding remaining in a blocking state.
This modification avoids to try to connect to an old-version client. An
Quit from splice(read) for avoiding to do splice(write) if there are no data.
When splice(read) returns negative or 0, that means no data. So, the recorder

Hi Steven,
I'm considering Integrated trace which is a trace merging system for a
virtualization environment. Why do we need this system? Because we want to
analyze latency problems for a virtualization environment. For example, a host
OS runs two guest OSs and those OSs are sharing HW devices
Add waitpid() when recorders are destroyed for avoiding zombie processes.
When udp_port is inappropriate, a parent process will destroy all child recorder
processes. Currently, the process does not wait for the termination of the
children, so those recorders can become zombie processes if the
