2. Make trap_pfault more like it is on other architectures.
3. Fix a bug in syscall() which caused system calls with more than
six arguments that are called through the wild card syscall to
have their arguments scrambled. This affected mmap due to the
(bogus) wrapper in libc.

Add some traces that can be useful but are also very loud.
Use defines for offsets into jmpbuf instead of magic numbers.
Fix a style bug.
Fixup comments.
Remove the explicit call to aio_proc_rundown() from exit1(), instead AIO
will use at_exit(9).
Add functions at_exec(9), rm_at_exec(9) which function nearly the
same as at_exec(9) and rm_at_exec(9), these functions are called
on behalf of modules at the time of execve(2) after the image
activator has run.
Use a modified version of tegge's suggestion via at_exec(9) to close
an exploitable race in AIO.
Fix SYSCALL_MODULE_HELPER such that it's archetecuterally neutral,
the problem was that one had to pass it a paramater indicating the
number of arguments which were actually the number of "int". Fix
it by using an inline version of the AS macro against the syscall
arguments. (AS should be available globally but we'll get to that
later.)
Add a primative system for dynamically adding kqueue ops, it's really
not as sophisticated as it should be, but I'll discuss with jlemon when
he's around.
specified by the sparc abi. We use numerically higher values for all
internal kernel types.
Remove soft trap types which need to be exposed to userland. They will
move to utrap.h.
their duration. This is still only effective as long as they are
only used in the static kernel. Code in modules may cause instruction
faults which makes these break in different ways anyway.
2. Add a load bearing membar #Sync.
3. Add an inline for demapping an entire context.

Bloat trapframe with many extra fields so we don't need extra structures.
Use small data types where possible.
Remove second copy of TF_DONE.
Remove mmuframe.
inclusion of VJ compression into sppp.
Now, instead of the need to include this and that and everything plus
the kitchensink in each of those drivers, struct sppp uses struct
slcompress as an opaque structure only referenced by a pointer. The
actual structure is then malloced at initialization time.
While i was at it, also fixed a bug where received VJ packets would only
be recognized if INET6 was defined.
