tsutsui | Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).
Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)
To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.
Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:

thorpej | Minor tweak to the pv_table management in the Hibler-derived m68k pmaps:
The head of the list is now a pv_header, which contains the first pv_entry
as well as a 16-bit attributes field (replaces the pmap_attributes array
plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified
cache-inhibited mappings.
Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies
are purely mechanical.

thorpej | 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.
