Use memset() to initialize struct ieee80211_rxinfo properly.

Sven Wolf noticed that scans on ral(4) are buggy ever since I added a new
field to this struct. Turns out a lot of drivers were initializing fields
one-by-one, leaving any newly added fields uninitialized by default.

Affected drivers may report wrong channel numbers for received beacons.
The net80211 stack will discard such beacons, assuming they were received
on the wrong channel due to signal leakage. Scanning is broken as result.

Nuke all occurrences of usbd_abort_pipe() if it gets called right
before usbd_close_pipe(), since usbd_close_pipe() already takes care
about aborting non-empty pipes.

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.

move counting if_opackets next to counting if_obytes in if_enqueue.

this means packets are consistently counted in one place, unlike the

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.

No need to include <net/if_arp.h>

This header is only needed because <netinet/if_ether.h> declares a
structure that needs it. But it turns out that <net/if.h> already
includes it as workaround.

A proper solution would be to stop declarting "struct ether_arp"
there. But no driver should need this header.
