Add the new cdldr CD bootstrap loader. This patch includes the following: - Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel arguments. - Add the cdldr bootstrap program. This program is tacked onto the beginning of the standard 3rd stage boot loader (/boot/loader) to form the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file is copied into memory instead and executed. The cdldr stub emulates the environment normally provided by boot2 and then starts the loader. This booting method does not emulate a floppy drive, but boots directly off of the CD. This should fix the problems some BIOS's have with emulating a 2.88 MB floppy image. - Add support to the loader to recognize that it has been booted by cdldr instead of boot2 and use a simpler method of extracting the BIOS boot device. 2000-01-27 21:21:01 +00:00			`# $FreeBSD$`

Thanks to David's patches, we can now simplify these makefiles further, and just use PROG directly (without FILES). Suggested by: bde 2004-04-28 21:31:21 +00:00			`PROG= cdboot`

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead and finish the job. ncurses is now the only Makefile in the tree that uses it since it wasn't a simple mechanical change, and will be addressed in a future commit. 2014-04-13 05:21:56 +00:00			`MAN=`

First round of cleanups to sys/boot/ makefiles: - do not use PROG for what's not a real C program, - use sys.mk transformation rules where possible, - only create the "machine" symlink on AMD64, - removed MAINTAINER lines in individual makefiles, - added the LIBSTAND defitinion to <bsd.libnames.mk>, - somewhat better contents in .depend files.

Don't use -N to set the OMAGIC with data and text writeable and data not page aligned. To do this, use the ld script gnu ld installs on my system. This is imperfect: LDFLAGS_BIN and LD_FLAGS_BIN describe different things. The loader script could be better named and take into account other architectures. And having two different mechanisms to do basically the same thing needs study. However, it's blocking forward progress on lld, so I'll work in parallel to sort these out.
