8554754c7b fix top(1) ZFS compressed ARC support
top(1) read the wrong amount of data from sysctl, uint64_t instead of
boolean_t, resulting in the stats not showing in many cases.

23648b7d73 bspatch: Remove backwards-compatibility sys/capability.h support
bspatch previously included sys/capability.h or sys/capsicum.h based
on __FreeBSD_version, as FreeBSD is the upstream for bsdiff and we may
see this file incorporated into other third-party software.

The Capsicum header is now installed as sys/capsicum.h in stable/10 and
FreeBSD 10.3, so we can just use sys/capsicum.h and simplify the logic.

e3d9ae4c56 bspatch: add sanity checks on sizes to avoid integer overflow
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.

76723b39ca Capsicumize bspatch
Move all of the fopen() and open() calls to the top of main()

Restrict each FD to least privilege (read/seek only, write only, etc)

c08cbc64dc Change bsdiff to use divsufsort suffix sort library instead of qsufsort,
which is more efficient.

Note that for now we do not create a separate library for libdivsufsort
because it's not used anywhere else.

ccfb965433 Add META_MODE support.

WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

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

ba10db9984 Add bsdiff and bspatch to the base system. These are tools for
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.
