[Spice-devel] [PATCH 0/2] spice migration interface (RHBZ 737921)

Spice client is required to connect to the migration target before/as migration
starts. Previously, it connected upon migration completion, however, the ticket
was set in the beginning, thus when migration time was >
ticket_expiration_time, spice failed to connect to the target.

Since the migration target is blocked after migration starts, we execute spice-client connection to the target before migration, upon client_migrate_info. We wait till the client is connected to the target, or till a timeout occurs.
In order to not block the iothread, this patch turns client_migrate_info to
asynchronous.

In addition, we changed the spice api:
(1) client_migrate_info need to call spice_server_migrate_connect
(2) spice_server_migrate_start/end need to be called upon migration start/end

** spice_server_start and the migrate_end_complete callback, were added for
   future use, in case we implement a real seamless spice migration

Spice server patches will be emailed next. They are for the 0.8 spice branch,
but will be ported to upstream soon.

Yonit Halperin (2):
  spice: turn client_migrate_info to async
  spice: support the new migration interface (spice 0.8.3)
