Clean up (or if antipodic: down) some of the msgbuf stuff.
Use an inline function rather than a macro for timecounter delta.
Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.
Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()
This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

This is obviously not a terribly used function as it's apparently been
broken forever.
It IS possible that this fix is wrong and that the KERNEL is wrong
(in which case you should fix if_ethersubr.c) either way it certainly has more hope of
working now than before. I'd take it to 2.2 except that obviously no-one cares :-)
with real copies. I'm sick of !@#&!^!@#*& mtree chowning directories in
my src/sys/* tree after it follows the symlinks. I still believe that
mtree is broken for doing this (introduced in mtree.c rev 1.5).
point to it rather than libscrypt.
This was how it was done prior to libscrypt being added in. This should
stop more people getting burnt with the /usr/lib -> /usr/lib/aout
transition, and the same when the ELF libs come online.
and we have not done an explicit 'cvs login', then use a default password
of "anoncvs". This allows things like:
setenv CVSROOT :pserver:anoncvs@anoncvs.freebsd.org:/cvs
cvs checkout src (without doing the normal 'cvs login' for pserver mode)
but this runs over the :pserver: protocol rather than the more troublesome
rsh. Naturally, the server had better be running in -R (readonly) mode :-)
helpful to stop it running /usr/libexec/aout/as for real while bootstrapping.
Only force a strict path when we really have built all the tools in
$OBJDIR/tmp/usr/libexec/*.
CVSROOT/passwd file is empty. A 'cvs login' still seems to be required
since the cvs client doesn't seem to believe it's possible to not need
a password (yet :-). This is intended for cheap anoncvs use.
This is mostly intended for use on freefall where we'd like to provide
a passwd file for easy anoncvs mirroring access, but don't want to open
up the pserver on freefall itself.
While here, some initial tweaks intended for allowing an empty pserver
password. I'm not sure that this works yet.
while calling libdiff. It's too ugly and not worth the recursion problems
when there is a malloc failure (which writes to stderr - now diverted via
the buf system, which calls malloc, which causes another error message etc).
We can live with the standard artificial slowdown, but reduce the time a
bit and only delay when we really need to (ie: when running as a server).
The usleep time could probably use some tuning, it basically needs to
replace the time that it used to take to fork a large process, exec gnudiff
and the time that gnudiff took before writing the initial output.
This eliminates a whole mess of other hacks I was considering that changed
use of xmalloc to alloca() etc. It was going too fast in the wrong
direction.
true in /etc/make.conf. Both qmail and smail use a different rmail, so
replacing rmail is a Bad Thing.

Move a.out libraries to /usr/lib/aout to make space for ELF libs.
Make rtld usr /usr/lib/aout as default library path.
Make ldconfig reject /usr/lib as an a.out library path.
Fix various Makefiles for LIBDIR!=/usr/lib breakage.
This will after a make world & reboot give a system that no
longer uses /usr/lib/*, infact one could remove all the old
libraries there, they are not used anymore.
We are getting close to an ELF make world, but I'll let this
all settle for a week or two...
net.inet.ip.icmp.bmcastecho = 0 by removing the extra check for the
address being a multicast address. The test now relies on the link
layer flags that indicate it was received via multicast. The previous
logic was broken and replied to ICMP echo/timestamp broadcasts even
when the sysctl option disallowed them.

Move our old a.out utils to /usr/libexec/aout.
Enable binutils and put the utils in /usr/libexec/elf
Enable objformat, a little helper program that calls the right
utils based on /etc/objformat and $OBJFORMAT.
This will enable the ELF generating tools.
Remember that this is only step one, the system is still compiled
and run in a.out format ONLY.
Problem left to solve: The BSD manpages wins over the GNU equivalents
as the are installed last. We need to distinguish between the manpages
somehow...
Prior to this change, Accidental recursion protection was done by
the diverted daemon feeding back the divert port number it got
the packet on, as the port number on a sendto(). IPFW knew not to
redivert a packet to this port (again). Processing of the ruleset
started at the beginning again, skipping that divert port.
The new semantic (which is how we should have done it the first time)
is that the port number in the sendto() is the rule number AFTER which
processing should restart, and on a recvfrom(), the port number is the
rule number which caused the diversion. This is much more flexible,
and also more intuitive. If the user uses the same sockaddr received
when resending, processing resumes at the rule number following that
that caused the diversion. The user can however select to resume rule
processing at any rule. (0 is restart at the beginning)
To enable the new code use
option IPFW_DIVERT_RESTART
This should become the default as soon as people have looked at it a bit
