Fix up flags passed to usbd_open_pipe_intr() - interrupt pipes are always opened exclusively, and the flags argument is passed to usbd_setup_xfer(). USBD_EXCLUSIVE_USE has the same value as USBD_NO_C
Fix up flags passed to usbd_open_pipe_intr() - interrupt pipes are always opened exclusively, and the flags argument is passed to usbd_setup_xfer(). USBD_EXCLUSIVE_USE has the same value as USBD_NO_COPY, which means that data transferred would not be copied to the buffer where the driver expects it.
None of these drivers actually used the interrupt data for anything, and in some the interrupt pipe code was #if 0'd out, so this doesn't change anything, but fixing this up prevents unwary developers like me from copying code that doesn't work.

As investigated by gerhard@ usbdi.c rev. 1.57 did add usbd_abort_pipe() to usbd_close_pipe(), but the drivers didn't get cleaned up afterwards.

Avoid calling usbd_set_config_no() in *_attach() and let the stack do it instead.
If anything bad happen due to a malformed descriptor it makes no sense to try to attach a driver, and bail before probing.
This is similar to the change to avoid calling usbd_set_config_index().

replace IFF_OACTIVE manipulation with mpsafe operations.
there are two things shared between the network stack and drivers in the send path: the send queue and the IFF_OACTIVE flag. the send queue is now protected by a mutex. this diff makes the oactive functionality mpsafe too.
IFF_OACTIVE is part of if_flags. there are two problems with that. firstly, if_flags is a short and we dont have any MI atomic operations to manipulate a short. secondly, while we could make the IFF_OACTIVE operates mpsafe, all changes to other flags would have to be made safe at the same time, otherwise a read-modify-write cycle on their updates could clobber the oactive change.
instead, this moves the oactive mark into struct ifqueue and provides an API for changing it. there's ifq_set_oactive, ifq_clr_oactive, and ifq_is_oactive. these are modelled on ifsq_set_oactive, ifsq_clr_oactive, and ifsq_is_oactive in dragonflybsd.
this diff includes changes to all the drivers manipulating IFF_OACTIVE to now use the ifsq_{set,clr_is}_oactive API too.

shuffle struct ifqueue so in flight mbufs are protected by a mutex.
the code is refactored so the IFQ macros call newly implemented ifq functions. the ifq code is split so each discipline (priq and hfsc in our case) is an opaque set of operations that the common ifq code can call. the common code does the locking, accounting (ifq_len manipulation), and freeing of the mbuf if the disciplines enqueue function rejects it. theyre kind of like bufqs in the block layer with their fifo and nscan disciplines.
the new api also supports atomic switching of disciplines at runtime. the hfsc setup in pf_ioctl.c has been tweaked to build a complete hfsc_if structure which it attaches to the send queue in a single operation, rather than attaching to the interface up front and building up a list of queues.
the send queue is now mutexed, which raises the expectation that packets can be enqueued or purged on one cpu while another cpu is dequeueing them in a driver for transmission. a lot of drivers use IFQ_POLL to peek at an mbuf and attempt to fit it on the ring before committing to it with a later IFQ_DEQUEUE operation. if the mbuf gets freed in between the POLL and DEQUEUE operations, fireworks will ensue.
to avoid this, the ifq api introduces ifq_deq_begin, ifq_deq_rollback, and ifq_deq_commit. ifq_deq_begin allows a driver to take the ifq mutex and get a reference to the mbuf they wish to try and tx. if there's space, they can ifq_deq_commit it to remove the mbuf and release the mutex. if there's no space, ifq_deq_rollback simply releases the mutex. this api was developed to make updating the drivers using IFQ_POLL easy, instead of having to do significant semantic changes to avoid POLL that we cannot test on all the hardware.
the common code has been tested pretty hard, and all the driver modifications are straightforward except for de(4). if that breaks it can be dealt with later.

Kill a bunch of DVACT_DEACTIVATE handlers whose only purpose were to set the 'dying' flag of a device. Such handlers are useless now that usbd_detach() already set this flag.
Even if the purpose of this flag is questionnable on OpenBSD because DVACT_DEACTIVATE acts as a pre-detach event, this is just a first small step towards the simplification of the autoconf(9) device states.
This cleaning is now possible thanks to the work of pirofti@ to convert all the USB drivers to properly use usbd_is_dying().
