When passing around unsigned and signed transactions, outputs
and key images are passed along (outputs are passed along unsigned
transactions from the hot wallet to the cold wallet, key images
are passed along with signed transations from the cold wallet
to the hot wallet), to allow more user friendly syncing between
hot and cold wallets.
The vast majority of transactions will have just one tx pubkey,
but a bug with cold wallet signing caused two such keys to be
there, with the second one being the real one.
When receiving an answer packet, the command code was passed
to the callback instead of the error code. This was hiding
the "command not found" failure from the peer, and in turn
causing the code to attempt to deserialize a non existent
reply string.
I forgot to bump it previously when changing RPC, most notably
for the addition of the unlocked field in the histogram RPC.
This causes new wallets to not realize when they're talking to
an older daemon, and get confused trying to get outputs to use
as fake outs. This otherwise gratuitous bump ensures than old
daemons will be detected by wallets using this code.
Added a new command to the P2P protocol definitions to allow querying for support flags.
Implemented handling of new support flags command in net_node. Changed for_each callback template to include support flags. Updated print_connections command to show peer support flags.
Added p2p constant for signaling fluffy block support.
Added get_pool_transaction function to cryptnote_core.
Added new commands to cryptonote protocol for relaying fluffy blocks.
Implemented handling of fluffy block command in cryptonote protocol.
Enabled fluffy block support in node initial configuration.
Implemented get_testnet function in cryptonote_core.
Made it so that fluffy blocks only run on testnet.
This will be when we can't find common ground between the peer's
short chain history and our blockchain.
This fixes bad peers claiming a higher blockchain height from never
dropped, and keeping the node in synchronizing state forever, since
we will never get blocks from that peer.
