virtio-serial: Use a struct to pass config information from proxy

Instead of using a single variable to pass to the virtio_serial_init
function, use a struct so that expanding the number of variables to be
passed on later is easier.

virtio-serial: kill VirtIOSerialDevice

VirtIOSerialDevice is like VirtIOSerialPort with just the first two
fields, which makes it pretty pointless. Using VirtIOSerialPort
directly works equally well and is less confusing.

[Amit: - rebase
- rename 'dev' to 'port' in function params in virtio-serial.h ]...

virtio-serial: Let virtio-serial-bus know if all data was consumed

The have_data() API to hand off guest data to apps using virtio-serial
so far assumed all the data was consumed. Relax this assumption.
Future commits will allow for incomplete writes.

virtio-serial: Add support for flow control

This commit lets apps signal an incomplete write. When that happens,
stop sending out any more data to the app and wait for it to unthrottle
the port.

Move stdbool.h

Move inclusion of stdbool.h to common header files, instead of including
in an ad-hoc manner.

virtio-serial: Apps should consume all data that guest sends out / Fix virtio api abuse

We cannot indicate to the guest how much data was consumed by an app for
out_bufs. So we just have to assume the apps will consume all the data
that are handed over to them....

virtio-serial: Implement flow control for individual ports

Individual ports can now signal to the virtio-serial core to stop
sending data if the ports cannot immediately handle new data. When a
port later unthrottles, any data queued up in the virtqueue are sent to...

virtio-serial: Use control messages to notify guest of new ports

Allow the port 'id's to be set by a user on the command line. This is
needed by management apps that will want a stable port numbering scheme
for hot-plug/unplug and migration.

Since the port numbers are shared with the guest (to identify ports in...

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...
