zd1211rw and bcm43xx are interested in being notified when ERP IE conditions
change, so that they can reprogram a register which affects how control frames
are transmitted.
This patch adds an interface similar to the one that can be found in softmac.

Similarly to CTS protection, whether short preambles are used for 802.11b
transmissions should be a per-subif setting, not device global.
For STAs, this patch makes short preamble handling automatic based on the ERP
IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been
restricted to AP-only subifs.
ieee80211_txrx_data.short_preamble (an unused field) was removed.
Unfortunately, some API changes were required for the following functions:
- ieee80211_generic_frame_duration
- ieee80211_rts_duration
- ieee80211_ctstoself_duration
- ieee80211_rts_get
- ieee80211_ctstoself_get
Affected drivers were updated accordingly.

mac80211 informs the driver what the short and long retry values are through
set_retry_limit(), but when packets are being transmitted it did not inform the
driver which of the 2 retry limits should actually be used.
Instead it sends the actual value, but for drivers that can only set the retry limit
and the register and in the descriptor need to indicate which of the limits should
be used this is not really useful.
This patch will add a IEEE80211_TXCTL_LONG_RETRY_LIMIT flag to the
ieee80211_tx_control structure. By default the short retry limit should be
used but if the flag is set the long retry should be used.
This does not prevent the driver to ignore the request for "no retry" packets,
but at least those will be send out with the short retry limit. But there is no
perfect cure for this problem.. :(

The sta_info code has some awkward locking which prevents some driver
callbacks from being allowed to sleep. This patch makes the locking more
focused so code that calls driver callbacks are allowed to sleep. It also
converts sta_lock to a rwlock.

The semantics of not having an add_interface callback are not well
defined, this callback is required because otherwise you cannot obtain
the requested MAC address of the device. Change the documentation to
reflect this, add a note about having no MAC address at all, add a
warning that mac_addr in struct ieee80211_if_init_conf can be NULL and
finally verify that a few callbacks are assigned by way of BUG_ON()
