[PATCH] hostap: Start using net/ieee80211.h

Browse Source 
Preparations for starting to use net/ieee80211 instead of private
IEEE 802.11 implementation. Include net/ieee80211.h and
net/ieee80211_crypt.h into files that will be needed these in the
future. Remove duplicate definitions from hostap_common.h and
rename WLAN_FC_GET_{TYPE,STYPE} macros for now sinc net/ieee80211.h
is using incompatible definitions. This will be resolved in the
future by updating Host AP to use the versions that do not shift
type/stype.
