maps standard boot flags to corresponding RB_* values use BOOT_FLAG() in port's MD code as appropriate as discussed on tech-kern, add new boot flags -v, -q for booting verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET boot flags; also add FreeBSD-compatible bootverbose macro and NetBSD-specific bootquiet macro for hpcmips, use new bootverbose instead of it's own hpcmips_verbose Tested on i386, and to limited extend (compile of affected files) also for mvme68k, hp300, luna68k, sun3.
