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. Discussed on: freebsd-arch MFC before: 5.5-RELEASE Tested by: Several million users (earlier version). 2005-08-06 01:59:06 +00:00			`# $FreeBSD$`
