On systems without xonly mmu hardware-enforcement, we can still mitigate against classic BROP with a range-checking wrapper in front of copyin() and copyinstr() which ensures the userland source doesn't overlap the main program text, ld.so text, signal tramp text (it's mapping is hard to distinguish so it comes along for the ride), or libc.so text. ld.so tells the kernel libc.so text range with msyscall(2). The range checking for 2-4 elements is done without locking (because all 4 ranges are immutable!) and is inexpensive.

Remove dangerous user-settable "addr" variable from MI boot loader, and only compile tty-related code (stty command, tty variable) on platforms where it makes sense for the boot loader to control it, rather than the PROM/firmware/whatever.

Introduce the KEEPKERNELS variable: if this is set either in mk.conf or the environment, 'make cleandir' does not descend into kernel build directories. Thus, kernel object files survive 'make build' on slower architectures.
