while waiting for an interrupt (rather than spinning on the runqueue status
bits), since the other cpu can put stuff in there and the sleeping cpu may
not get an interrupt for a while. When we have a reschedule IPI, this can
come back.

things like libskey.so to be dynamically self contained.
Things like md5(1) where speed is critical should still link with libmd.a,
but for things like login, where it's a once-off call if skey is used, it's
not worth the hassle.
.if in Makefiles. bsd.prog.mk and bsd.lib.mk do not depend on it however.
Allow overriding of the -soname arg when building the lib*crypt.so* libs
since libdescrypt.so and libscrupt.so both need a -soname of libcrypt.so
so that the symlink is obeyed at runtime rather than at compile time.
since 2.1.x make(1) apparently does not have the -m switch to set both
the the bsd.*.mk and sys.mk location, and this breaks 'make world' from a
2.1.x system.
size in terms of lines (instead of bytes). When changing video mode
in ioctl SW_XXX commands, syscons checks scp->history_size and
allocate a history buffer at least as large as the new screen size.
(This was unnecessary before, because HISTORY_SIZE was as large as 100
lines and this is bigger than the maximum screen size: 60 lines).
Similar adjustment is done in ioctl CONS_HISTORY command too.

are met:
1) The BIOS indicates that there is exactly 64MB of RAM, and
2) The memory size isn't specified with the MAXMEM option or
the npx0 msize hack,
...then do a speculative memory probe beyond the 64MB's until the
first bad page is encountered. This is an admitted hack, but should
nonetheless deal with detecting the correct amount of memory in nearly
all of the modern systems with >64MB of RAM.
Also made a change that will cause the list of detected memory chunks
to be printed if bootverbose is set.
