Scott Long 9df1a6dd61 Add functions and macros and refactor code to make it easier to manage 
fast taskqueues.  The following have been added:

TASKQUEUE_FAST_DEFINE() - create a global task queue.
    an arbitrary execution context.
TASKQUEUE_FAST_DEFINE_THREAD() - create a global taskqueue that uses a
    dedicated kthread.
taskqueue_create_fast() - create a local/private taskqueue.

These are all complimentary of the standard taskqueue functions.  They are
primarily useful for fast interrupt handlers that can only use spinlock for
synchronization.

I personally think that the taskqueue API is starting to get too narrow and
hairy, but fixing it will require a major redesign on the API.  Such a
redesign would be good but would break compatibility with FreeBSD 6.x, so
it really isn't desirable at this time.
