monitor: Port handler_0 to use QDict

This commit ports command handlers that receive no arguments to use
the new monitor's dictionary.

It might seem no sense to do this, as the handlers have no arguments,
but at the end of this porting work all handlers will have the same...

Migration via unix sockets.

Implement migration via unix sockets. While you can fake this using
exec and netcat, this involves forking another process and is
generally not very nice. By doing this directly in qemu, we can avoid
the copy through the external nc command. This is useful for...

set migration max downtime

provide a monitor command to allow one to set the maximum
downtime he is willing to suffer during migration, in seconds.
"ms", "us", "ns" and "s" are accepted as modifiers.

This parameter will be used by ram_save_live() code to determine...

add non-arbitrary migration stop condition

Currently, we're entering migration's stage 3 when
a treshold of 10 pages remain to be transferred in the system.

This has hurt some users. However, any proposed threshold is
arbitrary by nature, and would only shift the annoyance....

monitor: Decouple terminals (Jan Kiszka)

Currently all registered (and activate) monitor terminals work in
broadcast mode: Everyone sees what someone else types on some other
terminal and what the monitor reports back. This model is broken when
you have a management monitor terminal that is automatically operated...

monitor: Rework API (Jan Kiszka)

Refactor the monitor API and prepare it for decoupled terminals:
term_print functions are renamed to monitor_* and all monitor services
gain a new parameter (mon) that will once refer to the monitor instance
the output is supposed to appear on. However, the argument remains...

Reintroduce migrate-to-exec: support (Charles Duffy)

KVM's live migration support included support for exec: URLs, allowing system
state to be written or received via an arbitrary popen()ed subprocess. This
provides a convenient way to pipe state through a compression algorithm or an...

Introduce TCP live migration protocol

This patch introduces a tcp protocol for live migration. It can be used as
follows:

qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio
<vm runs for a while>
(qemu) migrate tcp:localhost:1025

On the same system:...

Introduce UI for live migration

This patch introduces a command line parameter and monitor command for starting
a live migration. The next patch will provide an example of how to use these
parameters.
