qapi: add dirty bitmap status
Bitmaps can be in a handful of different states with potentially
more to come as we tool around with migration and persistence patches.
Management applications may need to know why certain bitmaps are
unavailable for various commands, e.g. busy in another operation,
busy being migrated, etc.
Right now, all we offer is BlockDirtyInfo's boolean member 'frozen'.
Instead of adding more booleans, replace it by an enumeration member
'status' with values 'active' and 'frozen'. Then add new value
'disabled'.
Incompatible change. Fine because the changed part hasn't been
released so far.
