This introduces:
* a basic wtap interface
* a HAL, which implements an abstraction layer for implementing
different device behavious;
* A visibility plugin, which allows for control over which nodes
see other nodes (useful for mesh work.)
It doesn't yet implement sta/adhoc/hostap modes but these are quite
feasible to implement.
Monthadar uses it to do 802.11s mesh verification.
The userland tools will be committed in a follow-up commit.

Add the ability for /dev/null and /dev/zero to accept
being set into non blocking mode via fcntl(). This
brings the code into compliance with IEEE Std 1003.1-2001

remove prototypes of a bunch of functions that had their implementations
removed in pfsync v5.
would go negative after using the "-z" option to zero out the stats.
This patch fixes that by not zeroing out the srvcache_size field
for "-z", since it is the size of the cache and not a counter.

the memory allocator used by netmap. No functional change,
two small bug fixes:
- in if_re.c add a missing bus_dmamap_sync()
- in netmap.c comment out a spurious free() in an error handling block
u_int. With the auto-sized buffer cache on the modern machines, UFS
metadata can generate more the 65535 pages belonging to the buffers
undergoing i/o, overflowing the counter.

bpf_iflist list which reference the specified ifnet. The existing implementation
only removes the first matching bpf_if found in the list, effectively leaking
list entries if an ifnet has been bpfattach()ed multiple times with different
DLTs.
Fix the leak by performing the detach logic in a loop, stopping when all bpf_if
structs referencing the specified ifnet have been detached and removed from the
bpf_iflist list.
Whilst here, also:
- Remove the unnecessary "bp->bif_ifp == NULL" check, as a bpf_if should never
exist in the list with a NULL ifnet pointer.
- Except when INVARIANTS is in the kernel config, silently ignore the case where
no bpf_if referencing the specified ifnet is found, as it is harmless and does
not require user attention.

from the interactive loader(8) prompt and beastie_disable="YES" is set
in loader.conf(5). In this case menu.rc is not evaluated and consequently
menu-unset does not have a body yet. This results in the ficl warning
"menu-unset not found" when try-menu-unset invokes menu-unset.
Check for beastie_disable="YES" explicitly, so that the try-menu-unset
word will not attempt to invoke menu-unset because the menu will have
never been configured. [1]
Use the sfind primitive as a last resort as an additional safer approach
conjuring a foreign word safely. [2]
