In the MPSAFE TTY branch, I noticed PTY's to be leaked, because
dhclient's privileged process was run inside the session of, say, the
login shell. Make sure we call setsid() here.

rather than write locking: while we need to maintain a valid reference
to the inpcb and fix its state, no protocol layer state is modified
during an IPv4 UDP receive -- there are only changes at the socket
layer, which is separately protected by socket locking.
While parallel concurrent receive on a single UDP socket is currently
relatively unusual, introducing read locking in the transmit path,
allowing concurrent receive and transmit, will significantly improve
performance for loads such as BIND, memcached, etc.

by moving the positional argument handling code to a new file,
printf-pos.c, and moving common definitions to printflocal.h.
No functional change intended.
The first test comes from OpenBSD, and the others are additions or
adaptations.
This is based on OpenBSD's
src/regress/lib/libc/sprintf/sprintf_test.c, v1.3.
I deliberately did not use v1.4 because it's bogus.
In particular, encapsulate the state of the type table in a struct,
and add inline functions to initialize, free, and manipulate that
state. This replaces some ugly macros that made proper error handling
impossible.
While here, remove an unneeded test for NULL and a variable that is
initialized (many times!) but never used. The compiler didn't catch
these because of rampant use of the same variable to mean different
things in different places.
This commit should not cause any changes in functionality.
in practice, the error (currently) makes no difference because the computation
performed by KVADDR() hides the error. This revision fixes the error.
Also, eliminate a (now) unused definition.
maximum size of the kmem map can be greater than 4GB, there is little point
in making the kernel virtual address space larger than 6GB.

useful in massive hosting environment, where most users do not care about
autogenerated mails.
Setting recipient to null string disables default mails at all.

Now that the pseudo-interface cloner has an internal list of instances,
there is no need to create a softc. The softc only contains a pointer to
the ifp, which means there is no valid reason to keep it. While there,
remove the corresponding malloc-pool.

shell (which was the problem with the original implementation) and avoid
letting make see an empty definition (which was the problem with the current
implementation).
1. Save and restore the control part of the MXCSR in addition to the
i387 control word to ensure that the two are consistent.
Note that standards don't require longjmp to restore either control
word, and none of Linux, MacOS X 10.3 and earlier, NetBSD, OpenBSD,
or Solaris do it. However, it is historical FreeBSD behavior, and
bde points out that it is needed to make longjmping out of a signal
handler work properly, given the way FreeBSD clobbers the FPU state
on signal handler entry.
2. Don't clobber the FPU exception flags in longjmp. C99 requires them
to remain unchanged.

Without this change these devices are supported by the driver's family
support, but they then appear as "Adaptec RAID Controller" in boot
messages and the dev.aac.0.%desc sysctl.
