cfg80211: add wiphy_apply_custom_regulatory()

This adds wiphy_apply_custom_regulatory() to be used by drivers
prior to wiphy registration to apply a custom regulatory domain.
This can be used by drivers that do not have a direct 1-1 mapping
between a regulatory domain and a country.

mac80211: Add capability to enable/disable beaconing

This patch adds a flag to notify drivers to start and stop
beaconing when needed, for example, during a scan run. Based
on Sujith's first patch to do the same, but now disables

ath5k: honor the RTS/CTS bits

The ath5k driver didn't use set_rts_threshold or use_cts_prot, and also
didn't check the IEEE80211_TX_RC_USE_{RTS_CTS,CTS_PROTECT} RC flags.
Tell the hardware about these so RTS/CTS will work, and so the device
will work better in mixed b/g environments.

iwl3945: report killswitch changes even if the interface is down

Currently iwl3945 is not able to report hw-killswitch events while the
interface is down. This has implications on user space tools (like
NetworkManager) relying on rfkill notifications to bring the interface
up once the wireless gets enabled through a hw killswitch.

Thus, enable the device already in iwl3945_pci_probe instead of iwl3945_up
and poll the CSR_GP_CNTRL register to update the killswitch state every
two seconds. The polling is only needed on 3945 hardware as this adapter
does not use interrupts to signal rfkill changes to the driver (in case no
