These bits are shared already between ipw2x00 and hostap, and could
probably be shared both more cleanly and with other drivers.  This
commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.

After 13 years of use, it looks like my email address is finally going
to disappear. While this is likely to drop the amount of incoming spam
greatly ;-), it may also affect more appropriate messages, so let's
update my email address in various places. In addition, Host AP mailing
list is subscribers-only and linux-wireless can also be used for
discussing issues related to this driver which is now shown in
MAINTAINERS.

This patch adds ieee80211 TKIP build_iv() method to support hardwares
that can do TKIP encryption but relies on ieee80211 layer to build
the IV. It also changes the build_iv() interface to return the key
if possible after the IV is built (this is required by TKIP).

This patch contains an attempt to properly build hostap.o without
#include'ing C files.

To help in reducing the number of include dependencies, several files were
touched as they were getting needed headers indirectly for stuff they use.

Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
linux/dccp.h include twice.

Changed crypto method from requiring a struct ieee80211_device reference
to the init handler.  Instead we now have a get/set flags method for
each crypto component.

Setting of TKIP countermeasures can now be done via
set_flags(IEEE80211_CRYPTO_TKIP_COUNTERMEASURES)

Fix TKIP, repeated fragmentation problem, and payload_size reporting

1. TKIP encryption
    Originally, TKIP encryption issues msdu + mpdu encryption on every
    fragment. Change the behavior to msdu encryption on the whole
    packet, then mpdu encryption on every fragment.

2. Avoid repeated fragmentation when !host_encrypt.
    We only need do fragmentation when using host encryption. Otherwise
    we only need pass the whole packet to driver, letting driver do the
    fragmentation.

3. change the txb->payload_size to correct value
    FW will use this value to determine whether to do fragmentation. If
    we pass the wrong value, fw may cut on the wrong bound which will
    make decryption fail when we do host encryption.

NOTE:  This requires changing drivers (hostap) that have
extra_prefix_len used within them (structure member name change).
