Update xfer->frlengths for input isoc transfer. Based on patches from
SOMEYA Yoshihiko.
Also fix error handling for isoc transfer somewhat; usb_transfer_complete
shouldn't be called for more than once.

Fix several nits. Mostly from SOMEYA Yoshihiko.
- Call usbd_transfer_complete at splusb.
- Fix a botched for loop in ohci_rem_ed.
- In ohci_close_pipe, wait 1ms after removing an ED to avoid possible race
condition.
The splusb change is non-functional on FreeBSD.
The botched loop and race condition changes came from us.
This patch is non-functional.

the dataphysend calculation could only possibly work if the virtual buffer
is also physically contiguous. Calculate dataphysend by calculating the
ending virtual address first, then converting to a physical address.
The second bug applies only to NetBSD and OpenBSD and involves the curlen
calculation in the two-contiguous-physical-pages case (which we don't support).
Also cleanup the use of the OHIC_PAGE() macro on dataphysend and add a panic
if len goes negative (meaning we lost the physical page translation
representing the end of the buffer).
IMHO the dataphysend is still bokered since it might be misrepresented
by shared userland page mappings. The whole section needs to be rewritten
to use the virtual address range.

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.

Change DMAADDR macro slightly.
Update the $NetBSD$ tags to reflect this and make slight changes to

NetBSD have adopted our way of using the KERNADDR macro. Update
