Jouni Malinen 0187c41d88 Declare wpa_debug_* variables in src/utils/wpa_debug.h
These were somewhat more hidden to avoid direct use, but there are now
numerous places where these are needed and more justification to make
the extern int declarations available from wpa_debug.h. In addition,
this avoids some warnings from sparse.
