error: Replace qemu_error() by error_report()

error_report() terminates the message with a newline. Strip it it
from its arguments.

This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for...

virtio-serial: don't set MULTIPORT for 1 port dev

Since commit 98b19252cf1bd97c54bc4613f3537c5ec0aae263, all
serial devices declare MULTIPORT feature.
To allow 0.12 compatibility, we should clear this when
max_nr_ports is 1.

virtio-serial-bus: Fix bus initialisation and allow for bus identification

This commit enables one to use multiple virtio-serial devices and to
assign ports to arbitrary devices like this:

-device virtio-serial,id=foo -device virtio-serial,id=bar \
  -device virtserialport,bus=foo.0,name=foo \...

virtio-console: qdev conversion, new virtio-serial-bus

This commit converts the virtio-console device to create a new
virtio-serial bus that can host console and generic serial ports. The
file hosting this code is now called virtio-serial-bus.c.

The virtio console is now a very simple qdev device that sits on the...

virtio-serial-bus: Maintain guest and host port open/close state

Via control channel messages, the guest can tell us whether a port got
opened or closed. Similarly, we can also indicate to the guest of host
port open/close events.

virtio-serial-bus: Add a port 'name' property for port discovery in guests

The port 'id' or number is internal state between the guest kernel and
our bus implementation. This is invocation-dependent and isn't part of
the guest-host ABI.

To correcly enumerate and map ports between the host and the guest, the...
