Extended thread dispatching support.

For basic support see reactor threading API docs.

    Call the function C{f} using a thread from the given threadpool and return
    the result as a Deferred.

    This function is only used by client code which is maintaining its own
    threadpool.  To run a function in the reactor's threadpool, use
    C{deferToThread}.

    @param reactor: The reactor in whose main thread the Deferred will be
        invoked.

    @param threadpool: An object which supports the C{callInThreadWithCallback}
        method of C{twisted.python.threadpool.ThreadPool}.

    @param f: The function to call.
    @param args: positional arguments to pass to f.
    @param kwargs: keyword arguments to pass to f.

    @return: A Deferred which fires a callback with the result of f, or an
        errback with a L{twisted.python.failure.Failure} if f throws an
        exception.

    Run a function in the reactor from a thread, and wait for the result
    synchronously.  If the function returns a L{Deferred}, wait for its
    result and return that.

    @param reactor: The L{IReactorThreads} provider which will be used to
        schedule the function call.
    @param f: the callable to run in the reactor thread
    @type f: any callable.
    @param a: the arguments to pass to C{f}.
    @param kw: the keyword arguments to pass to C{f}.

    @return: the result of the L{Deferred} returned by C{f}, or the result
        of C{f} if it returns anything other than a L{Deferred}.

    @raise Exception: If C{f} raises a synchronous exception,
        C{blockingCallFromThread} will raise that exception.  If C{f}
        returns a L{Deferred} which fires with a L{Failure},
        C{blockingCallFromThread} will raise that failure's exception (see
        L{Failure.raiseException}).
