Fix issue #11005453: [SUW] G+ profile creation for new user broken

The main problem here was a mistake when turning a single process
structure to a multi-package-process structure with a common
process.  When we cloned the original process state, if there were
any services already created for the process for that package, they
would be left with their process pointer still referencing the
original now common process instead of the package-specific process,
allowing the active counts to get bad.  Now we switch any of those
processes over to the new package-specific process.

There was also another smaller issue with how ServiceRecord is
associated with a ServiceState -- we could be waiting for an
old ServiceRecord to be destroyed while at the same time creating
a new ServiceRecord for that same service class.  These would share
the same ServiceState, so when the old record finally finished
destroying itself it would trample over whatever the new service
is doing.

This is fixed by changing the model to instead of using an "active"
reference count, we have an object identifying the current owner
of the ServiceState.  Then when the old ServiceRecord is cleaning
up, we know if it is still the owner at that point.

Also some other small things along the way -- new Log.wtfStack()
method that is convenient, new suite of Slog.wtf methods, fixed
some services to use Slog.wtf when catching exceptions being
returned to the caller so that we actually know about them.
