qmp: handle stop/cont in INMIGRATE state

Right now, stop followed by an incoming migration will let the
virtual machine start. cont before an incoming migration instead
will fail.

This is bad because the actual behavior is not predictable; it is
racy with respect to the start of the incoming migration. That's...

mirror: add support for on-source-error/on-target-error

Error management is important for mirroring; otherwise, an error on the
target (even something as "innocent" as ENOSPC) requires to start again
with a full copy. Similar to on_read_error/on_write_error, two separate...

monitor: Allow add-fd to any specified fd set

The first call to add an fd to an fd set was previously not
allowed to choose the fd set ID. The ID was generated as
the first available and ensuing calls could add more fds by
specifying the fd set ID. This change allows users to...

block: add block-job-complete

While streaming can be dropped as soon as it progressed through the whole
image, mirroring needs to be completed manually for two reasons: 1) so that
management knows exactly when the VM switches to the target; 2) because
for other use cases such as replication, we may leave the operation running...

block: introduce BLOCK_JOB_READY event

Even for jobs that need to be manually completed, management may want
to take care itself of the completion, not requiring the user to issue
a command to terminate the job. In this case we want to avoid that
they poll us continuously, waiting for completion to become available....

mirror: introduce mirror job

This patch adds the implementation of a new job that mirrors a disk to
a new image while letting the guest continue using the old image.
The target is treated as a "black box" and data is copied from the
source to the target in the background. This can be used for several...

qmp: add NBD server commands

Adding an NBD server inside QEMU is trivial, since all the logic is
in nbd.c and can be shared easily between qemu-nbd and QEMU itself.
The main difference is that qemu-nbd serves a single unnamed export,
while QEMU serves named exports....
