fix two problems identified by matthew@: 1. though shalt not hold a mutex while sleeping, which kthread_create can do. instead of holding the wq mutex over the kthread_create and increasing the number of running threads after kthread_create succeeds, this counts the thread and drops the mutex before kthread_create. after the call it takes the mutex again and decrements the number of threads if the call failed. 2. if a workq is created during autoconf, the actual thread create is deferred to when the scheduler is running. if the workq is destroyed before then, the wq memory gets freed and then the deferred thread creation will be using freed memory. we now have a workq state variable so we can do the right thing at the different stages of the workqs lifetime. ok matthew@

when you add a task to a workq, it allocates memory to handle the task and shove it on a list. allocations can fail, so if something that wants to run a task later already has memory to handle the workq task then let it provide it via a new function called workq_queue_task. ok kettenis@

revert to a pre-mutex state. for unknown reasons, the mutexes do not provide sufficient exclusion on alpha, leading to self-locking panics.

remove the DIRECTOK flag. the caller semantics were too weird, and it's a bad idea to have functions that react unpredictably.
