Make this compile with POOL_DIAGNOSTIC, and add a POOL_LOGSIZE option.
...
Defopt these.

Prototype pool_print() and pool_chk() if DEBUG.
...
Initialize pool hash table with PR_HASHTABSIZE (i.e., 8) LIST_INIT()s
instead of one memset().
Only check for page != ph->ph_page if PR_PHINPAGE is set (in pool_chk()).
Print pool base pointer when reporting page inconsistency in pool_chk().

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.

bcopy(x, y, z) -> memcpy(y, x, z)

bcmp(x, y, z) -> memcmp(x, y, z)
bzero(x, y) -> memset(x, 0, y)

Instrument "idle pages" (i.e. pages which have no items allocated from
...
them, and could thus be freed back to the system).

Un-static pool_head; vmstat wants to find it.

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.

Re-vamped pool manager.
...
* support for customized memory supplier
* automatic page reclaim by VM system
* time-based hysteresis
* cache coloring (after Bonwick's "slabs")
