Some deployed implementations do not include the mandatory Network
Key attribute when a WPS Credential is for an open network. Allow
this to improve interoperability since the actual key value is not
really needed for open networks.
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
External Registrar in Vista may include NULL termination in the Network
Key when encoding an ASCII passphrase for WPA/WPA2-PSK. As a workaround,
remove this extra octet if present.
