In addition to the spinlock, use the lockmgr() to serialize access to
...
the back-end page allocator. This allows the back-end to sleep since we
now relinquish the spin lock after acquiring the long-term lock.

Add an alternate pool page allocator that can be used if the pool is
...
never accessed in interrupt context. In the UVM case, this uses the
kernel_map, to reduce usage of the previous kmem_map resource.

Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.

Instrument "idle pages" (i.e. pages which have no items allocated from

them, and could thus be freed back to the system).

A few small changes to how pool pages are allocated/freed:
...
- If either an alloc or release function is provided, make sure both are
provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
kmem_alloc_poolpage()/kmem_free_poolpage()
rather than doing it here. These functions may use pmap hooks to
provide alternate methods of mapping pool pages.
