Ingo Weinhold 453a2bdd18 Replaced the locking strategy (formerly a recursive lock for the depot and
one for each per CPU store):
* The depot is now protected by a R/W lock combined with a spinlock. It is
  required to either hold read lock + spinlock or just the write lock.
* When accessing the per CPU stores we only need to acquire the read lock
  and disable interrupts. When switching magazines with the depot we
  additionally get the spinlock.
* When allocating a new magazine we do completely unlock.
