Backed out previous commit since it just causes panics unless a special
value for MSGBUF_SIZE is configured. MSGBUF_SIZE =
(32768 * bootverbose ? 2 : 1) is always 1 or 2, so there is not enough space
in the buffer for metadata, and blindly using the nonexistent space tends
to cause fatal pagefaults. I think
MSGBUF_SIZE = (32768 * (bootverbose ? 2 : 1)) would be always 32768 since
bootverbose is only statically initialized to 0 early when MSGBUF_SIZE is
used. MSGBUF_SIZE = (32768 * ((boothowto & RB_VERBOSE) ? 2 : 1)) should
work, but this belongs in <sys/msgbuf.h> even less than previous versions.
MSGBUF_SIZE shouldn't be a macro.
