Convert LUTestDelay to concurrent usage

In order to do so:
- We set REQ_BGL to False
- We implement ExpandNames

That's it, really.

Processor: Acquire locks before executing an LU

If we're running in a "new style" LU we may need some locks, as required
by the ExpandNames function, to be able to run. We'll walk up the lock
levels present in the needed_locks dictionary and acquire them, then run...

LogicalUnit: add ExpandNames function

New concurrent LUs will need to call ExpandNames so that any names
passed in by the user are canonicalized, and can be used by hooks,
locking and other parts of the code. This was done in CheckPrereq
before, but it's now splitted out, as it's needed for locking, which in...

Processor: Move LU execution to its own method

This makes the try...finally code simplier, and helps adding a more
complex locking structure before the actual execution. It also fixes a
concurrency bug caused by the fact that write_count was read before
acquiring the BGL, and thus spurious config update hooks run could have...

workerpool: Don't notify if there was no task

Workers have to notify their pool if they finished a task to make
the WorkerPool.Quiesce function work. This is done in the finally:
clause to notify even in case of an exception. However, before
we notified on each run, even if there was no task, thereby creating...
