Commit e2f5a9889a3a2bb8f1eed0cf274c7fbbabe3e9de was supposed to prevent new scan request from pushing out the old one. However, it did not really do that since eloop_deplete_timeout() returned 0 both for the case where the old timeout existed (and was sooner) and if the old timeout did not exist. It returned 1 only for the case where an old timeout did exist and was larger than the new requested value. That case used to result in wpa_supplicant_req_scan() rescheduling the timeout, but hew code in eloop_deplete_timeout() did the exact same thing and as such, did not really change anything apart from the debug log message. Extend the eloop_deplete_timeout() (and eloop_replenish_timeout() for that matter since it is very similar) to return three different values based on whether the timeout existed or not and if yes, whether it was modified. This allows wpa_supplicant_req_scan() to schedule a new timeout only in the case there was no old timeout. Signed-hostap: Jouni Malinen <j@w1.fi>

This package may include either wpa_supplicant, hostapd, or both. See README file respective subdirectories (wpa_supplicant/README or hostapd/README) for more details. Source code files were moved around in v0.6.x releases and compared to earlier releases, the programs are now built by first going to a subdirectory (wpa_supplicant or hostapd) and creating build configuration (.config) and running 'make' there (for Linux/BSD/cygwin builds).
