[PATCH 4/7] Support for adding UUID128 to extended inquiry response

[Inga Stotland <ingas@codeaurora.org>]

Whenever SDP service record is added/deleted/modified check for whether
class of device needs to be updated as well. If the update is
needed, proceed as before: new EIR will be written subsequently.
If the class of device is already present, just update EIR and return.
