- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()

Be somewhat more persuasive about enabling the port on a port reset.
USB protocol dictates that the port enable must be implied by the port
reset. To implement this on (at least) the VIA VT83C572 this means we
need to wait around tweaking the chip state until the port actually
transitions to enabled (or the device goes away). Likely fixes
kern/11018.
it is expected that they will not be enabled at the time that it
is called. This is reported to work around a problem in RELENG_4
where the kernel panics on boot if FAST_IPSEC and crypto support
are enabled.

command in case this setting was not saved. Since bandwidth reclamation
(-current only) often results in bus activity continuing to the end
of every frame, most transfers would fail with IOERROR if this
setting is missed.

code path to fix a bug in the non USB_USE_SOFTINTR path that caused
the usb bus to hang and generally misbehave when devices were unplugged.
In the process though it also reduced the throughput of usb devices because
of a less than optimal implementation under FreeBSD.
This commit fixes the non USB_USE_SOFTINTR code in uhci and ohci
so that it works again, and switches back to using this code path.
The uhci code has been tested, but the ohci code hasn't. It's
essentially the same anyway and so I don't envisage any difficulties.

debugging levels to off by default. Now that debug levels can be
tweaked by sysctl we don't need to go through hoops to get the
different usb parts to produce debug data.
frees it again. The idea was to perform M_WAITOK allocations in a
process context to reduce the risk of later interrupt-context
M_NOWAIT allocations failing, but in fact this code can be called
from contexts where it is not desirable to sleep (e.g. if_start
routines), so it causes lots of witness "could sleep" warnings.

Change DMAADDR macro slightly.
Update the $NetBSD$ tags to reflect this and make slight changes to
usb_mem.h so that we're in sync with each other.

Update dma memory access API a little.
NetBSD have adopted our way of using the KERNADDR macro. Update
the revision tags to show that we're in sync, and remove the casts
that they did in their adaptation.

Switch to the same abort mechanism as in [eo]hci; it should be more

drivers.
