Note that this introduces an explicit 2GB limit, but this was already
implicit in variable and function argument types.
This is based on the "non-cryptanalytic attacks against freebsd
update components" anonymous gist. Further refinement is planned.

Note that for now we do not create a separate library for libdivsufsort

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to

Still need to add real targets under targets/ to build packages.

constructing and applying binary patches; in particular, they perform
well (in the sense of constructing small patches) for executable code.
Both portsnap (coming to the base system Real Soon Now) and FreeBSD
Update (coming to the base system a bit later) use bspatch.
This is the same code as the bsdiff-4.2 which has been in the ports
tree (misc/bsdiff) for the past year, with the following exceptions:
1. The license is now the traditional 2-clause BSD;
2. Instead of forking and execing bzip2, the code now uses libbz2; and
3. Some minor changes have been made to fit this code into the base
system (adding $FreeBSD$ tags, putting bsdiff and bspatch into separate
directories, etc.)
This code is rather ugly and has lots of style bugs (mostly because I
wrote it before I had ever heard of style(9)). Some day I'll come
back and clean it up.
