Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

Fix the 'usb0: USB revision unknown, not supported' people have been seeing

A better version of the previous checkin. If the user specifies

When specifying additiona user-specified kernel compilation source
files in a 'files.XXX' file, config allows non-FreeBSD source files
with the same name as a FreeBSD source file to override the latter,
and in this situation it issues a warning.
However, if one of the user-specified files is actually a FreeBSD
source file (perhaps your kernel has some custom option that requires
that file), config mistakenly thinks it's a completely new file
and goes ahead and overrides all previous information for that file
(and issues the warning).

In one queue all the TDs (transfer descriptor, packets) for one transfer
are queued. Traverse the queues vertically and then horizontally.
This means that TDs for one xfer are transmitted back to back until the
first NAK or error condition. Up to now we transmitted a TD per frame
and transmitted the next TD in the next frame.
The old approach is more fair if you have the end of the queue point at
the beginning of the control transfer queue, but also a lot more overhead
due to the fact that the QHs have to be read more often.
The new approach squirts the packets down the line as fast as possible
for one transfer and then does the next one. In the current situation,
with fairly empty USB buses, this is a more sensible approach. We might
have to revisit the scheduler later however.
It speeds up large transfers (Zip drive, Host-To-Host adapters) on UHCI
by a factor of 5 and makes it as fast as OHCI on the bus.
The next problem to solve is the question why the limit is 300kb/s and
not 1000/kb/s (kb == kilobyte).

Replace the -q option to pwd_mkdb with a test for PW_SCAN_BIG_IDS in
the environment. This allows big ID warnings to be suppressed for
vipw and chpass as well.
Since the environment variable test is only performed for callers
of pw_scan() that do not set pw_big_ids_warning, the test can still
be overriden. Currently, chpass and pwd_mkdb are the only users
of pw_scan() and neither of them overrides the environment variable
test.

it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather

o Fix ep and ed pccard detach routines to use if_detach rather than just
if_down. if_detach destroys the device, while if_down just marks it
down. In this incarnation of the pccard things, we map the disable

ifconfig tried to down the device.

o remove now unused parts of struct slot

I did some tests and verified that the counts collected for writes

come from requests for read-ahead blocks). Note that you need
to compile a new version of mount to get the read counts printed
out. The old mount binary is completely compatible, the only
reason to install a new mount is to get the read counts printed.

Change the way we transfer links (again). The previous
method avoided all race conditions, but suffered from
sometimes running out of buffer space if enough clients
were piled up at the same time.
Now, the client pushes the link descriptor, one end of a
socketpair() and the ppp version via sendmsg() at the
server. The server replies with a pid. The client then
transfers any link lock with uu_lock_txfr() and writev()s
the actual link contents. The socketpair is now the only
place we need to have large socket buffers and the bind()ed
socket can keep the default 4k buffer while still handling
around 90 racing clients.
