Fix build when KERNHIST defined, but not UVMHIST

Rename pmap_md_pdetab_destroy to pmap_md_pdetab_fini to match
pmap_md_pdetab_init.

Call pmap_md_pdetab_fini from pmap_segtab_destroy.

In pmap_pte_reserve ensure we're atomically swapping out an invalid entry
otherwise concurrent updates might both think they've updated the entry.

MI PMAP hardware page table walker support.

This is based on code given to me by Matt Thomas a long time ago with
many updates and bugs fixes from me.

Rename pmap_segtab_t *stp to stb for consistency with a future
pmap_pdetab_t *ptb. pmap_pdetab_t *ptp would be far too confusing.

NFC. Same code before and after.

Sync with HEAD.

Consistently use %#jx instead of 0x%jx or just %jx in UVMHIST_LOG formats

%#jx vs %jx consistency in UVMHIST_LOG

Whitespace

Cast pointer arguments of UVMHIST_CALLARGS() into uintptr_t.

Appease GCC9 -Wpointer-to-int-cast on ILP32 environments.

Remove pte_zero_p and simply check against 0.

Remove the #if defined(__mips_n64) && PAGE_SIZE == 8192 and make the
check MI - all PTs are PAGE_SIZE aligned

Trailing whitespace

fix hpcmips and evbppc builds (wrong type in panic()).

move pmap segtab history into a new history of only 1000 entries,
but will overflow much slower than the main pmap history.

move various debug info into kernhist.  make pte array checker
into an array and use it in pmap_segtab_release() and
pmap_pte_reserve().  move check before MD callback(), incase it
wants to change ptes for some reason (they're passed in, but
this callback is currently always NULL.)

clean up some history logs to reduce the number of lines required.

Fix small tyop in a comment.

Improve a panic message ever so slightly

add pmaphist calls around seg_tab[] manipulation.  hopefully will
help find what causes this:

panic: pmap_segtab_alloc: pm_segtab.seg_tab[1010] != 0 (0x980000004eeb6068): from free list

Provide a pmap_segtab_deactivate for symmetry with pmap_segtab_activate
and use it in pmap_deactivate

Call pmap_md_xtab_{,de}activate from pmap_segtab_{,de}activate to be used
for PMAP_HWPAGEWALKER and any caches ops that might be required.

Provide empty (for now) pmap_md_xtab_{,de}activate functions on the
platforms that use sys/uvm/pmap

Use "segmap" for uvm_wait message in pmap_segtab_alloc

s/pte/ptep/ in pmap_pte_process for consistency with other code.  NFCI.

1TB is enough UVA for anyone... plus not all cpus can support more.
fix the start index generation in pmap_segtab_release() to
ensure it fits in the actual array.  fixes N64 binaries from
triggering later panic.  move the panic check itself into a
common function that is called from a couple of new places too.
