* Fixed a ton of wrong usages of B_CONTIGUOUS + B_FULL_LOCK.

* The use of B_{READ|WRITE}_AREA throughout the drivers is surely alarming.
  Defining these flags means that *every user* application can access these
  buffers read/write, it becomes visible in userspace like any other memory
  (just shared among all apps). I would like to ask each driver maintainer
  to see if that is really wished here. If you only need one app to be able
  to access it, cloning the area would be more appropriate.
* I came across the use of B_ANY_KERNEL_BLOCK_ADDRESS a number of times. This
  is almost completely useless for most usages, as it tries to align the
  virtual to a multiple of the size of the area. It just makes the allocation
  more likely to fail. Please only use where appropriate, and please review
  your code.
* Minor cleanup.
