avoid easily avoidable loss of precision when |x| is nearly 1.
Extended (64-bit) precision only moves the meaning of "nearly" here.
This probably could be done better by splitting up the range into
|x| <= 0.5 and |x| > 0.5 like the C version. However, ucbtest
does't report any errors in this version. Perhaps the C version
should be used anyway. It's only 25% slower now on a P5, provided
the C version of sqrt() isn't used, and the C version could be
optimized better.
Errors checked by: ucbtest
- avoid malloc() if the number of fds is small.
- pack the bits better so that `small' is quite large.
- don't waste time generating zero bits for null fd_set pointers or
scanning these bits.
Possibly improved select():
- free malloc()ed storage before returning. This is simpler and I
think huge select()s aren't worth optimizing since they are rare,
relative gain would be small and there would be tiny costs for all
selects().

might as well make it correspond to real version number (-current is
on the 3.0 branch) so at least the feature increments are guaranteed to
be linear.

execve() clears the P_SUGID process flag in execve() if the binary
executed does not have suid or sgid permission bits set.
This also happens when the effective uid is different from the real
uid or the effective gid is different from the real gid. Under
these circumstances, the process still has set id privileges and
the P_SUGID flag should not be cleared.

All signal() calls have been changed to pending_signal() calls.
pending_signal() is defined in the new sig.c file. It remembers
the handler and traps the signal with a function that will remember
the signal.
main.c now calls handle_signals() to actually call the required
handlers (if the above handler was called).
If this doesn't close PR2662 (was PR2347), I'll cry.
Joerg, I think this should go into 2.2, but I havn't done anything
about it because I'm bound to botch it with the new sig.[ch] files.
I've just "cvs add"'d sig.[ch] so far.... can you update to 2.2 and
tell me what you did ? Thanks.
Cleanup of the disconnected list was broken in the SCB paging case

Implement a clean mechanism for determining that we have exited the timeout
state and test for this in ahc_done instead of all over the place.
Bring back the use of AAP (Auto Access Pause) I don't think it was the
true cause of the bus hangs people were reporting.
We want to reset the bus if we've been through an Abort action, not if
we are a recovery SCB (one implies the other, but not vice-versa).
pr_usrreqs. Collapse duplicates with udp_usrreq.c and
tcp_usrreq.c (calling the generic routines in uipc_socket2.c and
in_pcb.c). Calling sockaddr()_ or peeraddr() on a detached
socket now traps, rather than harmlessly returning an error; this
should never happen. Allow the raw IP buffer sizes to be
controlled via sysctl.
negotiation messages may be tagged, we were overrunning the old buffer.
The variable that was getting squashed is updated before the message goes
out, causing corrupted SDTR or WDTR messages. Depending on the phases
traversed before message out, this could cause the wrong offset to be
negotiated allowing data overruns to occur. The problem is easier to
detect with wide targets on the chain since the allowed offset is smaller.
Also removed the unnecessary clearing of SPIORDY during the message out
phase. We don't rely on SPIORDY any more.

Successful lstat()s purged an existing entry as well as not caching the
result.
This bug was introduced in Lite1 by setting the LOCKPARENT flag for
[o]lstat() in order to support the inherit-attributes-from-parent-
directory misfeature for symlinks. LOCKPARENT was previously only set
for CREATEs and DELETEs. It is now set for LOOKUPs, but only for
[o]lstat(), so the problem wasn't very noticeable.
the old VFS_VFSCONF sysctl is enabled by default.
Initialize the vfc_vfsops field to non-NULL in sysctl_ovfs_conf()
so that the old VFS_VFSCONF sysctl actually works. The old (still
current) getvfsent.c uses this "kernel-only" field to decide which
vfs's are configured (the old implementation returned null entries
for unconfigured vfs's).
