a19e4685f7 Make CLKF_INTR() slightly less broken. The previous definition always 
tested true if the CPU was running in the kernel at the time of the clock
interrupt, therefore all such time (kernel and idle) was counted as interrupt
time.  The new definition simply punts on trying to count interrupt time,
which allows us to see kernel and idle time.

31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for 
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.
