Use opt_execfmt.h to get build options.

Only include elf32 hooks if we have elf32 defined and elf32 is not the
"native" emulation. This allows for having compat_netbsd32 without
elf32 (although it's probably not too useful), and also enables arm's
old-ABI usage of compat_netbsd32.

Separate the compat_netbsd32_coredump from the compat_netbsd32 and
coredump modules, into its own module.

Move all non-emulation-specific coredump code into the coredump module,
and remove all #ifdef COREDUMP conditional compilation. Now, the
coredump module is completely separated from the emulation modules, and
they can all be independently loaded and unloaded.

Rework the coredump code to have no explicit knownledge of how coredump
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.

When writing coredumps, don't write zero uninstantiated demand-zero pages.
Also, with ELF core dumps, trim trailing zeroes from sections. These two
changes can shrink coredumps by over 50% in size.

There's no need to pass a proc value when using UIO_SYSSPACE with
vn_rdwr(9) and uiomove(9).

catch up with latest sigctx changes; reported by John Heasley, thanks!

Catch up to Christos' SIGINFO changes.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

I can't win today -- make this link.

Move the code that walks the process's VM map during a coredump
into uvm_coredump_walkmap(), and use callbacks into the coredump
routine to do something with each section.

Fix compilation problems.

Make the coredump routine exec-format/emulation specific. Split
out traditional NetBSD coredump routines into core_netbsd.c and
netbsd32_core.c (for COMPAT_NETBSD32).
