Per discussion w/ chuck and chuck, restructure the md page stuff
...
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
...
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

We use 4K pages on MIPS systems (see mips_param.h), so override

PAGE_SIZE and friends to be compile-time constants.

USRIOSIZE had to be changed from 32 to 128,

Typo; user stack only needs to start one page below 0x80000000.

Move the start of the user stack down a little to account for the

virtual address checking done by the R8000 and some QED CPUs.

Don't bother allocating mb_map on these systems. Mbuf clusters are
...
allocated from a pool, and the MIPS and Alpha use KSEG to map pool
pages. So, mb_map wasn't actually being used. Saves around 4MB of
kernel virtual address space in a typical configuration.
Garbage-collect the related VM_MBUF_SIZE constant.
