Bjoern A. Zeeb 1edc20b769 wpa: ctrl_iface set sendbuf size 
In order to avoid running into the default net.local.dgram.maxdgram
of 2K currently when calling sendto(2) try to set the sndbuf size to
the maximum ctrl message size.
While on 14 and 15 this does not actually raise the limit anymore (and
be7c095ac9 raised it for syslogd and this),
FreeBSD 13 still requires this change and it will work as expected there.
In addition we always ensure a large enough send buffer this way
independent of kernel defaults.
The problem occured, e.g., when the scan_list result had enough BSSIDs
so the text output would exceed 2048 bytes.

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).
