UARTs when their divisor latch registers are selected while they are
doing output. Waiting for (some) output to drain is not permitted for
the TCSANOW case of tcsetattr(). NIST-PCTS easily detects bugs like
this by testing at at speeds that no one would want to use (50 bps).
Deleted stale comments related to flushing i/o. Flushing works properly
for 16550s according to NIST-PCTS (it can't work properly for 16450s).
This finishes fixing all sio(16550)-related bugs found by NIST-PCTS.
Many (mostly machine-dependent ones) are still missing. NIST-PCTS found
this bug for all the ioctls used to implement the POSIX tc* functions
(TIOCCBRK, TIOCDRAIN, TIOCSPGRP, TIOCSBRK, TIOCSTART and TIOCSTOP), and
I found FIOASYNC, TIOCCONS, TIOCEXCL, TIOCHPCL, TIOCNXCL, TIOCSCTTY and
TIOCSDRAINWAIT by inspection. TIOCSPGRP was ifdefed out for some reason.
Handle tcsetattr()'s historical speed conversions correctly and more
centrally:
- don't store speeds of 0 in the final termios struct. Drivers can now
depend on tp->t_ispeed and tp->t_ospeed giving the actual speed.
Applications can now depend on tcgetattr() being POSIX.1 conformant.
- convert from a proposed input speed of 0 to the proposed output speed
(except if that is 0, convert to the current output speed). Drivers
can now depend on the proposed input speed being nonzero.
- don't reject negative speeds. Negative speeds can't happen now that
speed_t is unsigned, and rejecting invalid speeds is a bug - tcsetattr()
is supposed to succeed if it can "perform any of the requested actions",
so it shouldn't fail in practice.
because libpam is built shared only. There is a way to build PAM
into a static library that contains all (or a selected subset) of
the modules. But our Makefiles don't support that yet. Until I get
that working, just force NOSHARED=no in login's Makefile. Of
course, it still won't work if NOPIC is set.

Change login to use PAM for authentication. I kept the built-in
passwd/NIS authentication support, to handle cases where the system
is missing its "/etc/pam.conf" file. S/Key and KerberosIV
authentication methods are removed from the login program, but
still available in PAM modules.
methods used by login. Changes to "/usr/bin/login" to use it will
be committed later today. The format of the file is described in
pam(8).
This sample file makes login behave in the traditional way. To
wit, it enables authentication via S/Key and passwd/NIS lookups.
KerberosIV authentication is present in the sample file but commented
out.
As a safety net and a transition aid, login will fall back on
built-in passwd/NIS authentication if this configuration file is
missing or if some other fatal PAM error occurs.
This file will eventually replace "/etc/auth.conf", but not until

the first time block 0 is read. This fix initialises the block
numbers to -1 which isn't the most correct thing for a daddr_t but
it isn't likely to cause a problem in the boot blocks and it could
do with a more thought out fix later.
The bug is probably benign on the i386 but on the alpha it can
cause initial file opens to fail. This is the cause of the "can't
open /boot/boot.conf" errors.
It appears on the alpha because of a number of combining factors.
On the alpha the LABELSECTOR is 0 so block 0 needs to be read in
from the media. The first time this happens you get a false hit
because the bc_blkno field is zero initially. Also, the timestamp
check against this cache hit succeeds because on the alpha a hacked
getsecs() function can return 0 when it starts counting so that
the zero initial timestamp + BCACHE_TIMEOUT is greater than the
current time until getsecs() has counted passed BCACHE_TIMEOUT.
The overall effect is that the first open() that occurs gets a
false cache hit and returns garbage to the bd_strategy() function
which then fails the open() call. This false hit then stays in the
cache until BCACHE_TIMEOUT getsecs() ticks have passed; all open()
calls during this time fail.
This explains why you can generally access the media by the time
you get to interp() and start issuing commands but the earlier
attempts to run the boot scripts are failing.
It's possible that this is causing the problem switching to the
mfsroot floppy as well but I haven't confirmed that.
almost always causes this panic for the curproc != pageproc case.
This case apparently doesn't happen in normal operation, but it
happens when vm_page_alloc_contig() is called when there is a memory
hogging application that hasn't already been paged out.

Build the ordered list of libraries in a variable "_libs" before
building any of them. This eliminates a little bit of duplicated
code. More importantly, it makes it easier to include or exclude
libraries with .if constructs, because the list can be built in
multiple steps using "+=".
