The read/write system calls return ssize_t because -1 is used to indicate

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where

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.
