non-i386 platforms.
I would however like to see a shared file here. If a function or two cannot
be shared we should create ${TARGET_ARCH}/kvm-fbsd-${TARGET_ARCH}.c.
xmalloc() and xrealloc() and the mixed usage of xmalloc in some .c's from
libiberty.a and other .c's from libreadline.so produces an unusable binary
on the Alpha.
While I am here, preventatively move other libs in the link order.

Correct backtrace was made more complex when the new signal trampoline
was introduced to support more than 32 signals, while keeping a modified
version of the old signal trampoline.
The 'where' command will now show:
#2 <signal handler called>
where appropiate.

code in ipl.s and icu_ipl.s that used them was removed when the
interrupt thread system was committed. Debuggers also knew about
Xresume* because these labels hide the real names of the interrupt
handlers (Xintr*), and debuggers need to special-case interrupt
handlers to get the interrupt frame.
Both gdb and ddb will now use the Xintr* and Xfastintr* symbols to
detect interrupt frames. Fast interrupt frames were never identified
correctly before, so this fixes the problem of the running stack
frame getting lost in a ddb or gdb trace generated from a fast
interrupt - e.g. when debugging a simple infinite loop in the kernel
using a serial console, the frame containing the loop would never
appear in a gdb or ddb trace.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

reading old a.out core files, which are totally 100% non-understandable
to the gdb floating-point reader if you have SSE turned on.
This should be the last of the world build breakers...
call and trap entry points so they're easy to find and change
- Use the cpuhead and allcpu list to locate globaldata for the current
cpu, rather than SMP_prvspace or __globaldata
- Use offsets into struct globaldata directly to find per-cpu variables,
rather than symbols in globals.o
