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/.

Fix minor cast too.
and I still dont know why, this was not failing on the non-kse kernel.
It certainly should have since things were using linker_kernel_file
unconditionally. This has highlighted a different problem though that
means that trying to do a kldload on a non-dynamic kernel will implode.
