x86: Split most of pmap.h into pmap_private.h or vmparam.h.

This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.

Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:

1. CPU-specific (different for i386/amd64) definitions used by...

2. common definitions, including Xenisms like xpmap_ptetomach,
   further used by...

3. more CPU-specific inlines for pmap_pte_* operations

So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3.  Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.

No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.

Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:

VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS

Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita.  There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

Adapt the machine/arch dependent code to the new {b,c}devsw reference
counting.

XXX Most of these will require testing by someone other than myself, as
I have a limited selection of hardware!

merge to -current.

implement bdev_size(9) wrapper around d_psize() routine, so we can take
the device lock in relevant places.  avoid doing so while actually dumping.

tested i386 crash dumps still work, and that all touched files compile.

fixes PR#45705.

revert dumpsys.c rev. 1.13 because it was reported to cause a problem.

Import PAE support for kvm(3):
- add kvm_i386pae.c (used for PAE memory translations), and update Makefile
  for libkvm build.
- in pdppaddr: pass a flag to indicate PAE mode. Use a bit ignored
  by the MMU. Mask address with PG_FRAME to avoid side effects.

Tested with vmstat(1)/netstat(1) to debug core files of PAE and !PAE
kernels. Older kernel dumps will default to native i386 (!PAE) mode.

XXX Currently, savecore(8) will fail to dump a PAE kernel in a !PAE
    environment (and reciprocally). So you need to sync and reboot
    with a kernel of the same mode as the one that crashed. Once the dump
    is successful, this does not matter anymore.

dump is not used here.

Adjustment for uvm/uvm_page.h.  More to follow later.

Fixes regarding paddr_t/pd_entry_t types in MD x86 code, exposed by PAE:

- NBPD_* macros are set to the types that better match their architecture
(UL for i386 and amd64, ULL for i386 PAE) - will revisit when paddr_t is
set to 64 bits for i386 non-PAE.

- type fixes in printf/printk messages (Use PRIxPADDR when printing paddr_t
values, instead of %lx - paddr_t/pd_entry_t being 64 bits with PAE)

- remove casts that are no more needed now that Xen2 support has been dropped

Some fixes are from jmorse@ patches for PAE.

Compile + tested for i386 GENERIC and XEN3 kernels. Only compile tested for
amd64.
