16 bits access is required by nsp driver to work in SMIT mode.
Since previously (1.65 and before in current, and 1.46.28 and before
in stable branch) 16 bits access was default, I hope it will break nothing.

so as to make the "picobsd" script less version-specific.
Improve handling of cross-builds (which requires creation of
includes and libraries for the new source tree).
The "picobsd" script will not probably work on -current because it still
uses 'vn' instead of 'md', but i am commiting it anyways to keep it
in sync with the version in -stable.

Context switch the cwp value. The register usage in cpu_switch will
be updated shortly to better reflect the fact that the current window
may change.

fork() return 0 (and success).

non-pointer values may be passed in it. Add appropriate casts.

with user windows in kernel mode. We split the windows using %otherwin,
but instead of spilling user window directly to the pcb, we attempt to
spill to user space. If this fails because a stack page is not resident
(or the stack is smashed), the fault handler at tl 2 will detect the
situation and resume at tl 1 again where recovery code can spill to the
pcb. Any windows that have been saved to the pcb will be copied out to
the user stack on return from kernel mode.
Add a first stab at 32 bit window handling. This uses much of the same
recovery code as above because the alignment of the stack pointer is used
to detect 32 bit code. Attempting to spill a 32 bit window to a 64 bit
stack, or vice versa, will cause an alignment fault. The recovery code
then changes the window state to vector to a 32 bit spill/fill handler
and retries the faulting instruction.
Add ktr traces in useful places during trap processing.
Adjust comments to reflect new code and add many more.

Remove the modified tte bit and add a softwrite bit. Mappings are only
writeable if they have been written to, thus in general modify just
duplicates the write bit. The softwrite bit makes it easier to distinguish
mappings which should be writeable but are not yet modified.
Move the exec bit down one, it was being sign extended when used as an
immediate operand.
Use the lock bit to mean tsb page and remove the tsb bit. These are the
only form of locked (tsb) entries we support and we need to conserve bits
where possible.
Implement pmap_copy_page and pmap_is_modified and friends.
Detect mappings that are being being upgraded from read-only to read-write
due to copy-on-write and update the write bit appropriately.
Make trap_mmu_fault do the right thing for protection faults, which is
necessary to implement copy on write correctly. Also handle a bunch
more userland trap types and add ktr traces.

where the headers should live, as the code references both "ip_fil.h" and
"netinet/ip_fil.h" (among others). As a consequence, put both
sys/contrib/ipfilter and sys/contrib/ipfilter/netinet to the include path
so either variant works.

DESTDIR. This avoids redundant information in the path when DOCDIR
points to some directory that already implies (or specifies) a certain
language. This is the case with the web site, where the release notes
are already installed under a language-specific directory. This
behavior is not being made mandatory because it might still be useful
to install all the translations in one directory, such as during
testing, or in a hypothetical release notes archive. Furthermore, it
is not being made the default because that breaks consistency with
stuff under doc/.
