wrong value in the comparison, leading to incorrectly setting the new
value.
This has been observed in the ZFS code. Without this we can lose track of
the reference count in a zrlock object.
We should move to use the generic atomic functions, however as this has
been observed I would prefer to have this working, then move to the generic
functions.

Fix two issues with the current event channel code, first ENABLED_SETSIZE is
not correctly defined and then using a BITSET to store the per-cpu masks is
not portable to other arches, since on arm32 the event channel arrays shared
with the hypervisor are of type uint64_t and not long. Partially restore the
previous code but switch the bit operations to use the recently introduced
xen_{set/clear/test}_bit versions.

- Add bcm2835_mbox_property for generic property request, it accepts
pointer to prepared property chan message and its size, forwards
it to MBOX and copies result back
- Make all bcm2835_mbox_XXX functions that use property channel go
through bcm2835_mbox_property path. Do not accept device_t as
an argument, it's not required: all DMA operatiosn should go
through mbox device, and all API consumers should report errors
on their side.
libopenbsd is an internal library which

This will allow us to bring in more
OpenBSD utilities into the FreeBSD base system.
We similarly use libnetbsd for bringing in stuff from NetBSD.

to transmit the buffer.
ath_tx_start() may manipulate/reallocate the mbuf as part of the DMA
code, so we can't expect the mbuf can be returned back to the caller.
Now, the net80211 ifnet work changed the semantics slightly so
if an error is returned here, the mbuf/reference is freed by the
caller (here, it's net80211.)
So, once we reach ath_tx_start(), we never return failure. If we fail
then we still return OK and we free the mbuf/noderef ourselves, and
we increment OERRORS.
