  qga: minimal support for fstrim for Windows guests

Unfortunately, there is no public Windows API to start trimming the
filesystem. The only viable way here is to call 'defrag.exe /L' for
each volume.

This is working since Win8 and Win2k12.

  qga: drop unused sockaddr in accept(2) call

ga_channel_listen_accept() is currently hard-coded to support only
AF_UNIX because the struct sockaddr_un type is used.  This function
should work with any address family.

Drop the sockaddr since the client address is unused and is an optional
argument to accept(2).

  qga: drop unnecessary GA_CHANNEL_UNIX_LISTEN checks

Throughout the code there are c->listen_channel checks which manage the
listen socket file descriptor (waiting for accept(2), closing the file
descriptor, etc).  These checks are currently preceded by explicit
c->method == GA_CHANNEL_UNIX_LISTEN checks.

Explicit GA_CHANNEL_UNIX_LISTEN checks are not necessary since serial
channel types do not create the listen channel (c->listen_channel).

As more listen channel types are added, explicitly checking all of them
becomes messy.  Rely on c->listen_channel to determine whether or not a
listen socket file descriptor is used.

  sockets: add AF_VSOCK support

Add the AF_VSOCK address family so that qemu-ga will be able to use
virtio-vsock.

The AF_VSOCK address family uses <cid, port> address tuples.  The cid is
the unique identifier comparable to an IP address.  AF_VSOCK does not
use name resolution so it's easy to convert between struct sockaddr_vm
and strings.

This patch defines a VsockSocketAddress instead of trying to piggy-back
on InetSocketAddress.  This is cleaner in the long run since it avoids
lots of IPv4 vs IPv6 vs vsock special casing.
