Move cpu-throttle.c from system to migration since it's
only used for migration; this makes us avoid exporting the
util functions and variables in misc.h but export them in
migration.h when implementing the periodic ramblock dirty
sync feature in the upcoming commits.
Since CPU throttle timers are only used in migration, move
their registry to migration_object_init.

Right now migration_throttle() tracepoint lacks very important
important information, i.e. no one could easily say how much the guest
is throttled. This makes difficult to debug guest quality of service
during migration.
This patch adds one more tracepoint into cpu_throttle_set() which is
actually doing this job.

They don't need to be in the global trace-events file and can have a
local trace header. Also add address_space_map tracepoint for tracking
mapping behaviour.
