assignment and the others are extended patterns.

Apart from detecting breakage earlier or at all, this also fixes a segfault
in the testsuite. The "handling" of the breakage left an invalid internal
representation in some cases.
Examples:
echo a; do echo b
echo `) echo a`
echo `date; do do do`

was incorrect as further down the road cons_probe() calls malloc() so the
former can't be called before init_heap() has succeed. Instead just exit
to the firmware in case init_heap() fails like OF_init() does when hitting
a problem as we're then likely running in a very broken environment where
hardly anything can be trusted to work.
subevalvar() incorrectly assumed that CTLESC bytes were present iff the
expansion was quoted. However, they are present iff various processing such
as word splitting is to be done later on.
Example:
v=@$e@$e@$e@
y="${v##*"$e"}"
echo "$y"
failed if $e contained the magic CTLESC byte.

extra MACHINE_ARCH symlink for certain platforms (such as pc98). The
support for creating these symlinks was added to sys/conf/kern.post.mk in
changeset 152964. The intention of that commit was to remove this code
from config(8), but config(8) was never updated.

The code is inspired by NetBSD sh somewhat, but different because we
preserve the old Almquist/Bourne/Korn ability to have an unquoted part in a
quoted ${v+word}. For example, "${v-"*"}" expands to $v as a single field if
v is set, but generates filenames otherwise.
Note that this is the only place where we split text literally from the
script (the similar ${v=word} assigns to v and then expands $v). The parser
must now add additional markers to allow the expansion code to know whether
arbitrary characters in substitutions are quoted.
Example:
for i in ${$+a b c}; do echo $i; done

If double-quote state does not match, treat the '}' literally.
This ensures double-quote state remains the same before and after a
${v+-=?...} which helps with expand.c.
It makes things like
${foo+"\${bar}"}
which I have seen in the wild work as expected.

- Sample CPU usage data from kern.cp_times, this makes for a far more
accurate and scheduler independent algorithm.
- Rip out the process list scraping that is no longer required.
- Don't update CPU usage sampling on every request, but every 15s
instead. This makes it impossible for an attacker to hide the CPU load
by triggering 4 samplings in short succession when the system is idle.
- After reaching the steady-state, the system will always report the
average CPU load of the last 60 sampled seconds.
- Untangling of call graph.

I'm unsure if some MIB standard states this must be the load average
for, eg. 300s, it looks like net-snmp isn't even bothering to implement
the CPU load reporting at all.

Note that poll() works on BPF devices is Snow Leopard

In xbb_detach() only perform cleanup of our taskqueue and
device statistics structures if they have been initialized.
This avoids a panic when xbb_detach() is called on a partially
initialized device instance, due to an early failure in
attach.
