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.
stuff
make this all compile with -Wall -Wno-main -Wmissing-prototypes
-Wstrict-prototypes -Werror , also compilable on 1.4.1
label itself as NetBSD/mvme68k instead of "BSD" in bootblock message
move bugcrt.c to libbug, remove bugcrt directory (bugcrt is still built
and used separately to rest of libbug)
convert sboot to use ordinary mvme68 libsa, instead of copying needed
stuff in libc_sa.c
convert to use version info generated by sys/conf/newvers_stand.sh
instead of previous version.c files, add necessary 'version' files
put chiptotime() to separate libsa file (used also by sboot/clock.c)
Thanks to Steve Woodford for help with this. Note that -current build
might be hosed by this change, will be addressed by Steve shortly.
