This patch allows switching from the standard recv to recvmsg for a qemu char
device. Switching allows file descriptors to be passed with SCM_RIGHTS to a
qemu process. Instead of receiving a buffer of data the recvmsg call back is
passed a 'struct msghdr'.
The patch also adds a function to add an eventfd as qemu char device. Perhaps
this should be a separate patch.
This is not an elegant solution to supporting recvmsg so suggestions are
especially welcome.
Use the sendfd/closefd commands that Mark introduced.
