Permit selection of discovery mode (btle vs classic)

This change introduces the new API but does not yet implement the specific selection.

In any case BlueZ does not need any specific implementation as classic and BTLE
devices are found using the same method. iOS does not need any specific implementation
as it only supports BTLE discovery.
