The pathlist is a whitelist of dirs and files; anything else returns ENOENT.
Recommendation is to use a narrowly defined list. Also add TAME_FATTR, which
permits explicit change operations against "struct stat" fields. Some
other TAME_ flags are refined slightly.
Not cranking libc now, since nothing commited in base uses this and the
timing is uncomfortable for others. Discussed with many; thanks for a
few bug fixes from semarie, doug, guenther.

if we're allowed to try and use large pages, we try and fit at least
8 of the items. this amortises the per page cost of an item a bit.

swapping endianness since nobody looks at it. Don't touch the actual
field in disklabel. Yet.

since it had been converted from kvm to sysctl. This was hiding a
bunch of TCP states which are important for network debugging.
Loop over the internet PCB tables to fill the network information
into the KERN_FILE_BYFILE sysctl result. Skip internet sockets
when looping over the file desciptors.

tests reported an EMSGSIZE error although the sent message was not
too large. The way backpressure was implemented for unix domain
sockets confused the check in sosend().
Unix domain sockets append data only to the recv buffer. To report
the amount of content to the sender, the high watermark of the send
buffer was reduced. This happend for SOCK_STREAM and SOCK_SEQPACKET.
Sosend checks wether atomic chunks could ever fit into the send
buffer which is limited by the high watermark. This happens for
SOCK_DGRAM and SOCK_SEQPACKET. For SOCK_SEQPACKET the combination
of these mechanisms resulted in an EMSGSIZE error when the buffer
got filled. This also happened when space could be created by
reading from the other end in contradiction to the semantics of
EMSGSIZE.
Do not emulate a send buffer that has no space. It is better to
fill the buffer with fake data than to reduce its size. Thus the
high watermark always contains the real value. When disconnecting,
reset the counters. Otherwise the socket layer would try to flush
non existing data in the send buffer.
Tested by jeremy@ with a C program and the ruby tests.

- Introduce new defines TTHIWATMINSPACE, TTMINHIWAT for some magic values
that are used in tty.c.
- Remove hiwat adjustments in ttwrite(). This fixes this codepath not
being interrupt safe.
- Change ttysetwater() to keep at least TTHIWATMINSPACE space above the high
water mark. This makes it consistent with ttycheckoutq(). Without this
change, the hiwat adjustment change above causes deadlocks in pty.

While here, reworking internal kern_ktrace.c bits to be able to pass
