Avi Kivity 54b76e82bc Merge "Make migration manager main-local" from Pavel
"
There are few places left that call for migration manager
by global reference. This set patches all those places
and makes the migration manager a service that locally
lives in main(). Surprisingly, the largest changes are to
get rid of global migration manager calls from ... the
migration manager itself.

Two tricks here. First, repair code gets its private global
migration manager pointer. That's not nice, but it aligned
with current repair design -- all its references are now
"global". Some day they all will be moved into sharded
repair service, for now these globals just describe the real
dependencies of the repair code.

Second is storage proxy that needs to call migration manager
to get schema. Proper layering makes migration manager sit
on top of storage proxy, so the direct back-reference is
not nice. To overcome this the proxy gets migration manager's
shared_from_this() pointer and drops all of them on stop.
This makes sure that by the time migration manager stops
no references from proxy exist.
