In case attach fails because of the priv check we leaked the

- Save td_oncpu in 'struct kthr' so the i386 target code can see which CPU
a thread is running on.
- Add a new frame unwinder for double fault frames. This unwinder is used
when "dblfault_handler" is encountered in the stack. It uses the CPU of
the current thread to lookup the base address of the TSS used for the
double fault from the GDT. It then fetches the various registers out
of the TSS similar to how the current trapframe unwinder fetches
registers out of the trapframe.

We may need to review the current 'good' results to make

The register layout is little different from memory-mapped stats
in the previous generation chips. In fact, it is bad because
registers in this range are cleared after reading them.

shared object files which have the same name as currently-installed
shared object files should be reinstalled after binaries are rolled
back. The order for rolling back updates is therefore
1. Install any old shared object files which can be installed without
overwriting a new shared object file.
2. Rollback everything which isn't a shared object or kernel file.
3. Rollback any shared object files which we didn't deal with in (1).
4. Rollback to the old kernel.

- Trying to eliminate another racing by replacing the timeout(9) with
callout APIs. In addition to that, the callout_drain() in an_detach()
help us to avoid a possible panic-on-free due to the callout API tries
to lock a destroyed mutex.
- In an_stats_update(), check the return value of an_read_record(). This
should reduce the chance of device removal(PCCARD) panic [2].
- Adding a comment to state the fact that an_stats_update() is now called
via callout(9) with a lock held [2].
