Reduce the number of arguments passed between these functions by
creating a special-purpose struct.

This is mentioned in the Handbook but it is not as obvious to new
users why bpf is needed compared to the other largely self-explanatory
items in GENERIC.

would access memory before the beginning of the string to match (the
suffix match starts at the end of both the string and the suffix and
proceedes to the begin until either the start of the suffix is hit
or the character does not match). This could lead to a memcpy copying
into random memory. Fix this by checking the length of the string to
match too and replacing the Lst_Find calls with LST_FOREACH loops
(last part by me).

building the rescue binary. This fixes a problem with NO_TCSH, where
the "make obj" stage of buildworld doesn't recurse into bin/csh,
resulting in csh build-tools being put into /usr/src/bin/csh.

last in the list rather than first.
This makes the resouces print in the 4.x order rather than the 5.x order
(eg fdc0 at 0x3f0-0x3f5,0x3f7 is 4.x, but 0x3f7,0x3f0-0x3f5 is 5.x). This
also means that the pci code will once again print the resources in BAR
ascending order.
w/o problems than I was before... This simply brings back the knote_delete
as knlist_delete which will also drop the knote's, instead of just clearing
the list and seeing _ONESHOT...
Fix a race where if a note was _INFLUX and _DETACHED, it could end up being
modified... whoopse..

style changes to reduce diffs to my tree.

floating-point arithmetic on i386. Now I'm going to make excuses
for why this code is kinda scary:
- To avoid breaking the ABI with 5.3-RELEASE, we can't change
sizeof(fenv_t). I stuck the saved mxcsr in some discontiguous
reserved bits in the existing structure.
- Attempting to access the mxcsr on older processors results
in an illegal instruction exception, so support for SSE must
be detected at runtime. (The extra baggage is optimized away
if either the application or libm is compiled with -msse{,2}.)
I didn't run tests to ensure that this doesn't SIGILL on older 486's
lacking the cpuid instruction or on other processors lacking SSE.
Results from running the fenv regression test on these processors
would be appreciated. (You'll need to compile the test with
-DNO_STRICT_DFL_ENV.) If you have an 80386, or if your processor
supports SSE but the kernel didn't enable it, then you're probably out
of luck.
Also, I un-inlined some of the functions that grew larger as a result
of this change, moving them from fenv.h to fenv.c.
system have been attached, but no later. This ensures that we do
not explore ohci or uhci busses before the companion echi controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.
Some further changes are needed on architectures that do not currently
allow hooks to be inserted before configure_final() - alpha, ia64,
powerpc and sparc64. On these architectures the exploration will
now be delayed until the usb kthread runs.
