fix uan for python scan, add default constructor

Bug 881: Update RELEASE_NOTES and CHANGES.html

Bug 881: WifiInformationElement method renaming Some renaming proposed by Nicola: SerializeInformation => SerializeInformationField DeserializeInformation => DeserializeInformationField DeserializeIE => Deserialize SerializeIE => Serialize ...and some I've extrapolated: GetInformationSize => GetInformationFieldSize DeserializeOptionalIE => DeserializeIfPresent

Bug 881: Make Ssid and SupportedRates derive from WifiInformationElement

Bug 881: Bring Wi-Fi IE serdes intelligence into WifiInformationElement object Introduce WifiInformationElement methods SerializeIE(), DeserializeIE(), and DeserializeOptionalIE() (the latter for use when the IE of interest might not be present), which know how to deal with the IE as a whole. Make use of these in mesh subsystem where WifiInformationElement-derived objects are used. Also add empty implementation of Print() method of WifiInformationElement so that IEs that don't care about being displayed don't need to implement this.

Bug 881: Change WifiElementId to WifiInformationElementId

Bug 881: Extract WifiInformationElement(Vector) core to wifi module This patch aims to bring the core of the current WifiInformationElement and WifiInformationElementVector classes into the wifi module, where they can then enjoy greater use (currently they are in the mesh module and contain mesh-specific aspects).
