DPP: Common configurator/bootstrapping data management

Browse source 
Merge the practically copy-pasted implementations in wpa_supplicant and
hostapd into a single shared implementation in dpp.c for managing
configurator and boostrapping information. This avoid unnecessary code
duplication and provides a convenient location for adding new global DPP
data.
