If the uuid configuration parameter is not set, wpa_supplicant generates
an UUID automatically to allow WPS operations to proceed. This was
previously always using an UUID generated from the MAC address. This
commit adds an option to use a random UUID instead. The type of the
automatically generated UUID is set with the auto_uuid parameter: 0 =
based on MAC address (default; old behavior), 1 = random UUID.

Generate a SHA1 hash -based UUID from the local MAC address if the UUID
was not configured. This makes it easier to prepare for WPS since there
is no need to generate an UUID.
