Reduce default value of pcicb_membase to 0x2000000 (from 0x4000000)
since this seems to be the lower bound used by many systems.

spamming of the argv, almost back to the original code (except for NULL
padding of the string).
This makes this version of the sendmail source compile on 2.1.X again.
the argv array, causing parts of the argv[0] to be picked up several times
by libkvm, causing strange ps results for the nfs-server and nfs-master
processes.. :-]
(How many copies of setproctitle() do we need anyway? NetBSD has it in
libc and BSDI have it in libutil.)
successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm
that I found on some linux machine that I _think_ is running slackware 3.0.
There are still problems.. ld.so claims the libraries are the wrong
format, but it still runs anyway.. :-/ The QMAGIC ld.so also screams
about needing ld.so.cache, and running a linux ldconfig is quite
educational. You soon learn to run "chroot /compat/linux /bin/ldconfig"
where ldconfig is living in /compat/linux/bin. :-]
(Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)
XDR routines auto-generated by rpcgen don't quite match the format of
the original ones even though tey have the same names (that was one of
the things wrong with the old XDR routines).
(TTMAXHIWAT + OBUFSIZ + 100) in case someone changes OBUFSIZ. 200
was to allow 100 above high water for ordinary writes and another
100 for kernel printfs.
Increased the reserved output queue count from 512 to the maximum
output queue count. This prevents exhaustion of clists and increases
the output throughput for 8 cy lines by almost a factor of 2 (on
a system where there aren't many other open ttys so clists become
exhausted after about 4 active lines (or earlier if TTMAXHIWAT is
increased :-]).
ttwrite() behaves very badly when clists are exhausted:
(1) it sleeps on lbolt instead of on TSA_OLOWAT(tp).
This could be fixed adequately by sleeping on TSA_OLOWAT(tp).
The nonzero reserved count guaratees that space will become
available independent of other ttys, and a reserved count
of 512 is barely enough for efficiency.
(2) it drops output if space runs out in the middle of special
output processing. This is too hard to fix without hardening
the reserved count. The watermark processing guarantees that
space doesn't run out only if the advertised space is guaranteed.
Increasing the reserved output queue count defeats the point of
dynamic allocation of clists. Previously, about 2K of memory per
tty was reserved (the raw queue was already reserved). Now, about
3.5K is reserved. Reserving everything would take a whole 0.5K
more.
ttyflush() might be called from an interrupt handler. This fixes
panics in IXOFF mode at the cost of more failures to send the START
character to exit from IXOFF mode.
getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.
Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.
conf.c:
Removed stale #includes and comments.
LINT: add a couple of new/missing/undocumented options
files.i386: add linux code so that you can compile a kernel with static
linux emulation ("options LINUX")
i386/*: use #if defined(COMPAT_LINUX) || defined(LINUX) to enable static
support of linux emulation (just like "IBCS2" makes ibcs2 static)
The main thing this is going to make obvious, is that the LINUX code
(when compiled from LINT) has a lot of warnings, some of which dont look
too pleasant..
