DEVFS - Cleanup of dead functions/comments; various fixes
Cleanup of dead functions and structures and cleanup of C++-style
comments.
Fixes include:
- function devfs_node_is_accessible, which checks if the node is valid
and if it isn't a hidden node.
- calls to devfs_node_is_accessible from most vnops to ensure validity
of the devfs_node they operate on.
- Change of devfs_rule struct to use dynamically allocated memory
instead of using pre-sized buffers. This way we avoid wasting a lot
of memory for each devfs_rule.

kernel module loader - fix load dependencies from preload modules by kernel
The boot loader is supposed to load module dependencies but it misses
a few when e.g. 'snd_hda' is specified in loader.conf. This resulted
in the kernel itself trying to load the missing dependencies, but the
kernel was running the sysinits for those dependencies immediately during
the preload stage instead of registering them.
Pass a flag to the loader chain to register the sysinits instead of
running them if a dependency is loaded during the preload stage. This
fixes the problem. And also, by the way, the loader does not need to
load dependencies any more (though it still does).

TCP - Fix re-establishment issues if a client reboots
When the machine hosting the client side of a TCP connection
reboots without clearing the connection, the server side will
continue to believe that the connection is in an established
state. If the client attempts to reconnect using the same
port pair (after rebooting, typically), the sequence space checks
against DOS attacks on the server side will cause the SYN
packets to be dropped.
A dandy solution to this problem is to force a keep-alive within
half a second of receiving a SYN on an ESTABLISHED socket. The
server will revalidate the connection and, since the client is
actually alive, will get an immediately Reset. The the next
SYN attempt from the client will then succeed.
A SYN sent as part of a DOS attack has little effect other then
to cause the server to probe the established connection within
half a second of receiving the bogus SYN.
In particular, this fixes issues with TCP NFS connections. NFS
clients are often unable to umount the NFS mounts and the TCP
connection is left established through the reboot. Instead of
hanging on SYNs being simply dropped by the server, the server
now properly detects that the connection is in fact dead after
the first SYN and properly reestablishes it on the next one.

Implement autosizing TCP socket buffers.
Normally the socket buffers are static (either derived from global
defaults or set with setsockopt) and do not adapt to real network
conditions. Two things happen: a) your socket buffers are too small
and you can't reach the full potential of the network between both
hosts; b) your socket buffers are too big and you waste a lot of
kernel memory for data just sitting around.
With automatic TCP send and receive socket buffers we can start with a
small buffer and quickly grow it in parallel with the TCP congestion
window to match real network conditions.
New sysctls are:
net.inet.tcp.sendbuf_auto=1 (enabled)
net.inet.tcp.sendbuf_inc=8192 (8K, step size)
net.inet.tcp.sendbuf_max=
16777216 (16M, growth limit)
net.inet.tcp.recvbuf_auto=1 (enabled)
net.inet.tcp.recvbuf_inc=16384 (16K, step size)
net.inet.tcp.recvbuf_max=
16777216 (16M, growth limit)
Additionally, add limiters and sanity checks for TCP MSS (maximum segment
size) resource exhaustion attacks.

Repair rcenable(8) and rcdisable(8).
* rcenable(8) was not playing nicely with our three year old change to
no longer depend on _enable being appended to rc variables for starting
daemons etc. (i.e., foo_enable=yes and foo=yes both work).
* rcdisable(8) did not properly run rcstop(8) because that needs to be
run when the variable is still set to 'yes' and not after it's been
set to 'no'.

libc_r: fix bugs in openat()
The openat() wrapper was not locking its file descriptor argument.
Special case the magic AT_FDCWD descriptor in the file descriptor
locking code (_FD_LOCK() / _FD_UNLOCK()) to avoid EINVAL on locking.

make openat(2) a POSIX syscall instead of BSD one.
