Remove src/common from default header file path This makes it clearer which files are including header from src/common. Some of these cases should probably be cleaned up in the future not to do that. In addition, src/common/nl80211_copy.h and wireless_copy.h were moved into src/drivers since they are only used by driver wrappers and do not need to live in src/common.

Added support for enforcing frequent PTK rekeying Added a new configuration option, wpa_ptk_rekey, that can be used to enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP deficiencies. This can be set either by the Authenticator (to initiate periodic 4-way handshake to rekey PTK) or by the Supplicant (to request Authenticator to rekey PTK). With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP keys will not be used for more than 10 minutes which may make some attacks against TKIP more difficult to implement.
