i/o is done. Instead, pass an opaque cookie which is then passed to a
new routine, coredump_write, which does the actual i/o. This allows the
method of doing i/o to change without affecting any future MD code.
Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that
core_elf64.c uses core_elf32.c) and eliminate that code duplication.
cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill
the core structure and a second to actually write md parts of the coredump.
All i/o is nolonger random access and is suitable for shipping over a stream.

TODO:
1. since timer stuff gets called from an interrupt context, we could
preallocate ksiginfo_t's from the pool, so we don't need a kmem
pool.
2. probably the sa signal delivery syscall can be changed to take
a ksiginfo_t so we can use only one pool.
3. maybe when we add realtime signal support, add a resource limit
on the number of ksiginfo_t's a process can allocate.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
