wlan - Sync netproto/802_11 from FreeBSD part 1/N

* Sync netproto/802_11 from FreeBSD, fbsd git dd885b9a0a0e, May 11 2016.

wlan - Update wlan from Adrian / FreeBSD

* Update the wlan infrastructure, initially working with ath.

Remove empty DragonFly CVS IDs.

Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

Fix the way <sys/ioccom.h> is included throughout our tree.

The original intention was to include it only in header files which
define ioctl codes and not in .c or .h files which include headers
that define ioctl codes.

Adjust the tree to follow this idea.

Implement a generic TX rate control algorithm framework in 802.11 layer.
It is highly modulized so TX rate control algorithms can be added with ease.
Only limited interfaces are exported for driver to use, so most of the WiFi
drivers can be converted without too much trouble. It does not affect WiFi
drivers which are unaware of the new framework yet. Also, the new framework
allows TX rate control algorithm to be changed without touching the 802.11
state machine or reinitializing WiFi devices.

Two TX rate control algorithms are factored out from ath(4) driver:
1) Onoe TX rate control algorithm, which is suitable for almost any kinds of
WiFi NIC driver, especially for 11b devices. (*)
2) AMRR TX rate control algorithm, which should _only_ be used by the WiFi NIC
which supports multi-rate retry. More information of this TX rate control
algorithm is available at:
http://www-sop.inria.fr/rapports/sophia/RR-5208.html

In order to use the framework, individual WiFi driver needs to do following:
1) Tell the framework, which TX rate control algorithms it supports and which
one to be used as the default, by setting up ieee80211com.ic_ratectl.
2) Call ieee80211_ratectl_newstate() in driver's own newstate() function.
3) When set up hardware TX descriptors, which normally contain TX rate related
fields, instead of accessing ieee80211_node.ni_txrate directly, call
ieee80211_ratectl_findrate() to get a rate set from the framework.
4) When TX completes, feed TX state (e.g. failure, number of retries) to the
framework by calling ieee80211_ratectl_tx_complete().

Teach ifconfig(8) to print and set the TX rate control algorithm.


# (*) There is no formal paper for this algorithm, but following two papers
# have brief introduction of this TX rate control algorithm:

Sync 802.11 support with FreeBSD6:

Sync 802.11 support with FreeBSD6:
"it includes completed 802.11g, WPA, 802.11i, 802.1x, WME/WMM, AP-side
power-save, crypto plugin framework, authenticator plugin framework,
and access control plugin frameowrk."

Reoriganize the layout of netproto/802_11: put generic 802.11 layer, crypto
modules, authentication module and access control module into their own
directories. Header files are still in their original place.

Nuke all of the mutexing in generic 802.11, reorganize ieee80211_node table
scanning a little bit.

Rename FreeBSD's m_append() to ieee80211_mbuf_append(), rename FreeBSD's
m_unshare() to ieee80211_mbuf_clone() and put them into
netproto/802_11/wlan/ieee80211_dragonly.c
They are not generic enough for public using, at least for now.

Expose ieee80211_add_{ssid, xrates, rates}() which are used by acx(4)

Keep using opencrypto's AES implmentation for 802.11 CCMP crypto module


Sync ifconfig(8)'s 802.11 support with FreeBSD6


Update acx(4) and ndis(4) for the new 802.11 support

Sync iwi(4), ipw(4), wi(4) and ray(4) with FreeBSD6

For iwi(4):
- Fix ieee80211_node leakage
- Use a bitmap instead of FreeBSD's "unit number alloctor" to allocate IBSS node


Add generic 802.11 layer and crypto modules into GENERIC and LINT,
authentication module and access module are only added to LINT

Unhook awi(4) from GENERIC and LINT temporarily, since as of this commit it
is broken :( It will be fixed sometime later.


Thank Sam Leffler and many other people for their work on 802.11 support.

Thank Andrew Atrens and Adrian Michael Nida for submitting the patch.

Thank all the people that helped testing 802.11 patches for this commit

Use POSIX int types.

Add dev/wi/if_wavelan_ieee.h as netproto/802_11/if_wavelan_ieee.h, since
this is used by all wireless interfaces and beside the variable and constant
naming mostly wi(4) indepedent.
