file with different permissions and set a non-zero umask

the size of the test archives of course, so adjust the

taken from PR/121184 which was mechanically generated from similar
lists in the Linux ipaq driver. I then took the numbers we had in
usbdevs and filled in the right symbols and eliminated duplicates.

o List all devices FreeBSD supports (more on the way)
o Sort the list of supported devices
o Note this was introduced with FreeBSD 7.0
o Include the FreeBSD configuration synopsis
o Bump the man page date
o Put $FreeBSD$ where all the other usb man pages have it.
And add to build.
Should fix the current weirdness in ntpd/ntpdate where the current system
time is not read/updated.

allocated for posix_openpt(2). Unfortunately, that identifier
conflicts with other events already allocated to other systems in
OpenBSM. Assign a new globally unique identifier and conform
better to the AUE_ event naming scheme.
This is a stopgap until a new OpenBSM import is done with the
correct identifier, so we'll maintain this as a local diff in svn
until then.

Remove all the OtherBSD ifdefs. They are very out of date at this

In syscall, always make a copy of parameters from trapframe, this
becauses some syscalls using set_mcontext can sneakily change
parameters and later when those syscalls references parameters,
they will wrongly use register values in mcontext_t.

When I was hacking on uart(4) to make it work with the MPSAFE TTY layer,
I noticed there was a difference between the way syscons and uart work
with respect to consoles:
- The uart(4) driver sets cn_name to the corresponding ttyu%r node,
which means init(8) (which opens /dev/console) will have its output
redirected to /dev/ttyu%r. After /etc/rc is done, it can spawn a getty
on that device node as well.
- Syscons used a little different approach. Apart from the /dev/ttyv%r
nodes, it creates a /dev/consolectl node. This device node is used by
moused and others to deliver their data, but for some reason it also
acts as a TTY, which shares its stat structure with ttyv0. This device
node is used as a console (run conscontrol).
There are a couple advantages of this approach:
- Because we use two different TTY's to represent the 0th syscons
window, we allocate two sets of TTY buffers. Even if you don't use
/dev/consolectl after the system has booted (systems that don't run
moused), it seems the buffers are still allocated.
- We have to apply an evil hack to redirect input to /dev/consolectl.
Because each window (stat) is associated not associated with one TTY,
syscons solves this by redirecting all input to closed TTY's to
consolectl.
This means that opening /dev/ttyv0 while in single user mode will
probably cause strange things to happen with respect to keyboard input
redirection.
The first patch that I discussed with philip@ turned consolectl into a
symlink to ttyv0, but this was not a good idea, because in theory we
would want consolectl to be a simple device node, which contains all the
`privileged' ioctl()'s. Apart from that, it didn't work, because each
time /dev/ttyv0 got revoked, moused also lost its descriptor to deliver
input, which meant you had to plug out/in your mouse to make it work
again. This version just leaves the consolectl device the way it is. It
can still be used to write output to ttyv0, but it can no longer receive
any input.
In my opinion this patch is not a complete solution, but it's already a
step in the good direction. It would allow us to turn consolectl into a
special (non-TTY) device node in the far future. It shaves off 15 KB of
wasted TTY buffer space.
