monitor: QError support
This commit adds QError support in the Monitor.
A QError member is added to the Monitor struct. This new member
stores error information and is also used to check if an error
has occurred when the called handler returns.
Additionally, a new macro called qemu_error_new() is introduced.
It builds on top of the QemuErrorSink API and should be used in
place of qemu_error().
When all conversion to qemu_error_new() is done, qemu_error() can
be turned private.
Basically, Monitor's error flow is something like this:
1. An error occurs in the handler, it calls qemu_error_new()
2. qemu_error_new() builds a new QError object and stores it in
the Monitor struct
3. The handler returns
4. Top level Monitor code checks the Monitor struct and calls
qerror_print() to print the error

QError is a high-level data type which represents an exception

This patch adds the option to activate non-shared storage migration from the

The migration command is as follows:

char: don't limit data sent to backends to 1k per buffer
chardevs have a 'can_read' function via which backends specify
the amount of data they can receive. When can_read returns > 0,
apps can start sending data. However, each chardev driver here
allows a max. of 1k bytes inspite of the backend being able to
receive more.
The best we can do here is to allocate s->max_size bytes from
the heap on each call (which is the number returned by the
backend from the can_read call).
This is an intermediate step to bump up the bytes written in
each call to 4k.
