    details on how this works. (Trevor Norris) #4935

PR-URL: #5295

Implementations of error handling between node::MakeCallback() and
AsyncWrap::MakeCallback() do not return at the same point. Make both
executions work the same by moving the early return if there's a caught
exception just after the AsyncWrap post callback. Since the domain's
call stack is cleared on a caught exception there is no reason to call
its exit() callback.

Remove the SetVerbose() statement in the AsyncWrap pre/post callback
calls since it does not affect the callback call.

PR-URL: nodejs#4507
Reviewed-By: Fedor Indutny <[email protected]>

Add a scope that will allow MakeCallback to know whether or not it's
currently running. This will prevent nextTickQueue and the
MicrotaskQueue from being processed recursively. It is also required to
wrap the bootloading stage since it doesn't run within a MakeCallback.

Also pass Isolate to few methods and fix whitespace alignment.

After attempting to use ReThrow() and Reset() there were cases where
firing the domain's error handlers was not happening. Or in some cases
reentering MakeCallback would still cause the domain enter callback to
abort (because the error had not been Reset yet).

In order for the script to properly stop execution when a subsequent
call to MakeCallback throws it must not be located within a TryCatch.

PR-URL: nodejs#4507
Reviewed-By: Fedor Indutny <[email protected]>

Make sure that calling MakeCallback multiple times within the same stack
does not allow the nextTickQueue or MicrotaskQueue to be processed in
any more than the first MakeCallback call.

Check that domains enter/exit poperly with multiple MakeCallback calls
and that errors are handled as expected
