The separate header file is not needed since none of the driver wrappers
include it anymore. Move the WLAN_STA_* definitions back to be together
with struct sta_info definition.
This is an initial step in further cleaning up the EAPOL authenticator
use to avoid requiring direct accesses to the internal data structures.
For now, number of external files are still including the internal
definitions from eapol_auth_sm_i.h, but eventually, these direct
references should be removed.
This removes the hardcoded definition from Makefile and cleans up
source code by moving the mail HOSTAPD_DUMP_STATE blocks into separate
files to avoid conditional compilation within files.
