Use the wiphy RTS and fragmentation thresholds for initializing the FW
when possible. This mitigates a bug where previously set values are
forgotten after interface down/up.

Add checks before settings these values to ensure they are valid. Use
default values when invalid thresholds are configured.

Update the default RTS threshold to the maximum value given by the
specification.

In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending
stations.

In STA mode we register only for the MAX_TX_RETRY event. A TX failure is
interpreted as a loss of connection.

Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid
the inherent race condition of a mac80211 TX failure counter in addition
to the FW counter.

This patch depends on "mac80211: allow low level driver to report packet
loss"

little-endian values.  This patch makes sure that all the communication with

le*_to_cpu where appropriate.

Also, all the struct definitions for data exchanged with the firmware has
been changed to use __le16/32 types instead of u16/32.
