MAXSLP is defined to be a machine-independent scheduling parameter,
...
so move it into sys/param.h.

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.

Increase limits slightly. We're still not using all 32 address bits yet,
...
let alone 64.....

- rename 32bit USRSTACK32, and define USRSTACK to that if !__arch64__, so that
...
64bit code can see USRSTACK32
- bump the limits

Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size

(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.
