when an old ffs filesytem is first mounted (as a result, df reports disk
full on old ffs filesystem or mfs created by old binary). Problem first

filter or not. We only need to run the filter for bridge_forward() and
bridge_broadcast(). If we also run it for bridge_output(), we will run
the filter twice outbound per packet, so don't.
In bridge_ipf(), make sure we don't run m_cat() on a single mbuf chain
by checking to see (and remembering) if we need to m_split() the mbuf.
This fixes bridge + ipfilter on sparc.
Fixes PR kern/22063.
during a read(v)/write(v). If that happeded, we either passed a NULL
pointer or a pointer to something uninitialized as iov to ktrace,
or we got a memory leak. In read/write (w/o -v) we zero-initialize
the iov now to limit damage, in the -v calls the (dynamically allocated)
pointer is checked after the I/O.
- prevent BLOCKED upcalls on double page faults and during upcalls
- make libpthread handle blocked threads which hold locks
- prevent UNBLOCKED upcalls from overtaking their BLOCKED upcall
this adds a new syscall sa_unblockyield

- add simple lock for the list
- make get function remove the item from the list
- eliminate superfluous functions
thanks to enami and matt for the feedback.
XXX: could use STAILQ, but there is no way to remove an element without
rescanning the queue. We should really add a special iterator that can
do this.

The 20030905 workaround triggers too many warnings. TCP
sockets are back to blocking, and keepalives are turned on
to kill off dead sockets, as suggested by Leandro Santi.

Bugfix: the LMTP session caching code had problems with
SASL authentication after the first connection, and pipelining
was working poorly. Fix by Viktor Dukhovni, Morgan Stanley.

Workaround: besides SMTP server sockets, SMTP client sockets
can also hang on Solaris, as reported by Leandro Santi. In
order to deal with this at the root, all connection management
is now done by sane_accept() and sane_connect(). Both turn
on keepalives on Solaris.

Safety: set-gid commands don't trust TZ. File: msg_syslog.c.
