Move USRSTACK to the end of userland address space.

Remove the definition of USRTEXT. It has no relevance outside of the non-PIE
a.out world.

Hilarious! We are not ready yet for large stack random biases, due to
the stack region handling in uvm.

Expand STACKGAP_RANDOM to 2MB on machines with large user VA

Move declaration of struct vm_page_md from <machine/vmparam.h> to
<machine/pmap.h> where it belongs, and compensate in <uvm/uvm_extern.h>
by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested

by including <uvm/uvm_pmap.h> before <uvm/uvm_page.h>. Tested on all

refactor sys/param.h and machine/param.h. A lot of #ifdef _KERNEL is added
to keep definitions our of user space. The MD files now follow a consistant
order -- all namespace intrusion is at the tail can be cleaned up
independently. locore, bootblocks, and libkvm still see enough visibility to
build. Checked on 90% of platforms...

Remove the freelist member from vm_physseg

The new world order of pmemrange makes this data completely redundant
(being dealt with by the pmemrange constraints instead). Remove all code
that messes with the freelist.

While touching every caller of uvm_page_physload() anyway, add the flags
argument to all callers (all but one is 0 and that one already used
PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue
without it.

Should shrink the code a bit, as well.

matthew@ pointed out some mistakes i'd made.

Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.

Discussed and okay drahn@. Okay deraadt@.

oops, i forgot to check in the BRKSIZ define in uvm, but deraadt thinks
its better as a per arch MD define anyway. all default to MAXDSIZ as before.

more readable virtual memory size values.

The PIE address range defaults are too big for alpha and can land on or
above the stack. Fix by mapping PIE into the first quarter of the address
space before stack. "will do for now" miod@

use MD #define to choose stackgap size per-architecture. on sparc, special
case sun4c/sun4 -- because address space is more constrained

MAXSLP is not really an MD-configurable define so move it to param.h; miod@ testing

VM_KMEM_SIZE no longer needed.

Now that pmaps can have vm_page_md, make pmap_physseg optional.

MNN is no longer an option.
