HS 2.0: Add a command to retrieve icon with in-memory storage
This adds a new command based Hotspot 2.0 icon retrieval option. In short, here is the new command sequence: 1. REQ_HS20_ICON <bssid> <file-name> 2. event: RX-HS20-ICON <bssid> <file-name> <size> 3. GET_HS20_ICON <bssid> <file-name> <offset> <size> (if needed, repeat with larger offset values until full icon is fetched) 5. DEL_HS20_ICON <bssid> <file-name> REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST with the slight difference that an entry to store the icon in memory is prepared. The RX-HS20-ICON event has been augmented with BSSID, file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up to <size> bytes of icon data at offset <offset>. Each chunk is returned as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and file-name as well as the starting offset of the data. If there is no entry prepared for the icon when the ANQP result comes back, hs20_process_icon_binary_file falls back to legacy behavior. Finally the DEL_HS20_ICON command deletes (all) icons associated with BSSID and file-name (there could be several if retries are used and they have different dialog tokens).
