scan: Refactor bss_get_supported_ciphers
...
In many cases the pairwise and group cipher information is not the only
information needed from the BSS RSN/WPA elements in order to make a
decision. For example, th MFPC/MFPR bits might be needed, or
pre-authentication capability bits, group management ciphers, etc.
This patch refactors bss_get_supported_ciphers into the more general
scan_bss_get_rsn_info function

scan: Implement scan_oper_class_to_band
...
This function takes an Operating Channel and a Country String to convert
it into a band. Using scan_oper_class_to_band and scan_channel_to_freq,
an Operating Channel, a Country String and a Channel Number together can
be converted into an actual frequency. EU and US country codes based on
wpa_supplicant's tables.

scan: Fix crash
...
Sometimes the periodic scan is started and stopped before the timeout
was created. If periodic_scan_stop was called before, the timeout
object was not reset to NULL, which can lead to a crash.
