hostapd: Allow per-BSS (vif) configuration files

Browse source 
This provides a new option for configuring multiple virtual interfaces
(BSS) that share a single radio. The new command line parameter
-b<phyname>:<config file name> is used to define one or more virtual
interfaces for each PHY. The first such entry for a new PHY is used to
initialize the interface structure and all consecutive parameters that
have the same PHY name will be added as virtual BSS entries to that
interface. The radio parameters in the configuration files have to be
identical.

This can be used as an alternative for the bss=<ifname> separator and
multiple BSSes in a single configuration file design while still
allowing hostapd to control the PHY (struct hostapd_iface) as a group of
virtual interfaces (struct hostapd_data) so that common radio operations
like OLBC detection and HT40 co-ex scans can be done only once per real
radio.
