Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use

tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.
On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

Rework the way kernel include files are installed. In the new method,
...
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Reference Design NetBSD source code, obtained from the pages under

Use a separate variable to indicate whether the fault is from USR mode
...
or not rather than orring in a USER bit into the fault code variable.
This simplifies the fault switch statement and some of the addition
checks that are made of the fault code.
Move the printing of data abort information out into a separate function
rather then duplicating a lot of similar printf() statements.
Removed the fault_code variables from the prefetch abort handler as it
is not actually used for anything.

Major overhaul of pagetable handing.
...
Page tables no longer occupy space in the processes vm_map. This
means that page tables can now be allocated from pmap_enter() when the
first entry is made in the page table rather than relying on taking
a section fault and faulting in a page table. This also lowers
the overheads in creating and deleting page tables and simplfies
cpu_fork().
A result of this change is that problems with mapping zero page and
an associated pagetable when execing from a shared vm_map disappear
fixing PR5178.
