71b9cf739a slcompress: split one of the functions into two parts, to allow use by both
if_sl and if_ppp (from ppp-2.2), eliminating the nearly identical
 pppcompress.[ch] code.  Add maximum VJ compression states argument to
 sl_compress_init().
if_sl: call sl_compress_init() with the extra argument.

e8c8f201ec Make a putc()/b_to_q() to a clist that hasn't had cblocks reserved
non-fatal.  I've make it return an appropriate error to the caller instead
of panic()ing.

Handling an error condition is inherently more friendly than exploding
the kernel.. :-)  The new behavior is a little closer to traditional
clists, potentially making porting a little simpler.

Suggested by: bde (many months ago, I've been using this for a while..)

b372e37cdf The "od" driver. While the name is suggesting the use for
magneto-optical devices, it's scope can (and should) be widened to
cover all removable type 0 (direct) devices as well, since this class
of devices is sharing the same principles.  Things like suport for
media eject etc. will be supported later.  (Shunsuke is also working
on the problems arising out of the use of media with physical block
size != 512 bytes (which is not uncommon for MODs).

f60e6466c4 Include the "od" driver. (Oops, forgot to cvs add the driver file
itself.  Will do this after this commit.)

Make scsiconf more flexible about recognizing ``foreign'' devices.
This part needs to be rewritten some day to allow for matches whithou
strict version number checks, but either Julian as Peter seem to be
too busy right now, so i'm finally commiting the version that's
working for me stable now for several months, as an interim
workaround.

7788eaeb2f Mask netisrs during softtty isrs. This may fix PR 798. SLIP and PPP
line discipline interrupt handlers more or less expect to be called at
spltty() == splimp(), although they have internal splimp()s that are
bogus if this expectation is satisfied.  They are called at splsoftty()
from many tty drivers, so they were not protected from being reentered
from their own netisrs.  They certainly don't expect that but are
apparently remarkably robust if it occurs.  The problem in PR 798 seems
to be caused by pppstart() being reentered and finishing off the output
in progress by following the (stale) sc->sc_outm pointer.  Then the
original pppstart() finds garbage in m2 after MFREE(m, m2).  slstart()
doesn't have internal state like sc_outm so reentry of it probably only
causes out of order and dropped packets.

b396cd832c Rewamp the way we make sysctl variables to be easier to cope with.
The goal is to make them "user-friendly" :-)

In the end this will allow a SNMP style "getnext" function, sysctl editing
in the boot-editor and/or debugger, LKMs can define sysctl vars when
they get loaded, and remove them when unloaded and other interesting
uses for dynamic sysctl variables.

8e6b01171e Do a pass over the broken LKM's and update them to use the "new"
convention of having their entry point named "<modname>_mod"".
Symorder is enforcing this when the current bsd.kmod.mk is installed.

I've not tested all these, but at least they all compile now.

Reattach them to the makefile.

Note that the change that I made to symorder needs to be compiled and
installed before any LKM's will work - the last version was corrupting
the relocation tables.  A "make world" will to this, but if you
manually run a make on the lkm's you'll need to take care of it by
hand.

fca911ecf3 Set SCSIGO generically before we determine the phase instead of doing it
in each phase routine.  Saves a few instructions.

Be more careful in how we deal with SXFRCTL0.  Or in the control bits of
interest instead of using mvi.  The kernel driver will set the ULTRAEN
bit of SXFRCTL0 if we are using Ultra (20MHz) mode and we don't want to
clobber it.

In sdtr_to_rate divide by two if we are in ultra mode to get the correct
setting since its a 20MHz instead of 10MHz scale.

12bc45a8df Fix clist limits. They were usually one too low. E.g., for a limit of
TTYHOG = 1024 bytes, 10 cblocks were reserved.  This was thought to
provide 10 * CBSIZE = 1080 bytes of buffering, but if the head pointer
is at the end of a cblock, then it only provides 1 + 9 * CBSIZE = 973
bytes of buffering.  This caused serious data loss for ptys because the
flow control is deterministic and requires at least TTYHOG bytes of
buffering.  For ttys, if input flow control is used then there is
usually enough slop in the high watermark to avoid problems, and if
input flow control isn't used then a limit of 973 is not much different
from a limit of 1024.

Add prototypes.

Continue cleaning up new init stuff.
