'label' and 'account' APIs for wallet

A new 'label' API has been introduced for the wallet. This is intended as a replacement for the deprecated 'account' API. The 'account' can continue to be used in V0.17 by starting bitcoind with the '-deprecatedrpc=accounts' argument, and will be fully removed in V0.18.

The label RPC methods mirror the account functionality, with the following functional differences:

• Labels can be set on any address, not just receiving addresses. This functionality was previously only available through the GUI.
• Labels can be deleted by reassigning all addresses using the setlabel RPC method.
• There isn't support for sending transactions from a label, or for determining which label a transaction was sent from.
• Labels do not have a balance.

Here are the changes to RPC methods:

Deprecated Method	New Method	Notes
getaccount	getaddressinfo	getaddressinfo returns a json object with address information instead of just the name of the account as a string.
getaccountaddress	n/a	There is no replacement for getaccountaddress since labels do not have an associated receive address.
getaddressesbyaccount	getaddressesbylabel	getaddressesbylabel returns a json object with the addresses as keys, instead of a list of strings.
getreceivedbyaccount	getreceivedbylabel	no change in behavior
listaccounts	listlabels	listlabels does not return a balance or accept minconf and watchonly arguments.
listreceivedbyaccount	listreceivedbylabel	Both methods return new label fields, along with account fields for backward compatibility.
move	n/a	no replacement
sendfrom	n/a	no replacement
setaccount	setlabel	Both methods now: allow assigning labels to any address, instead of raising an error if the address is not receiving address. delete the previous label associated with an address when the final address using that label is reassigned to a different label, instead of making an implicit getaccountaddress call to ensure the previous label still has a receiving address.

Changed Method	Notes
addmultisigaddress	Renamed account named parameter to label. Still accepts account for backward compatibility if running with '-deprecatedrpc=accounts'.
getnewaddress	Renamed account named parameter to label. Still accepts account for backward compatibility. if running with '-deprecatedrpc=accounts'
listunspent	Returns new label fields. account field will be returned for backward compatibility if running with '-deprecatedrpc=accounts'
sendmany	The account named parameter has been renamed to dummy. If provided, the dummy parameter must be set to the empty string, unless running with the -deprecatedrpc=accounts argument (in which case functionality is unchanged).
listtransactions	The account named parameter has been renamed to dummy. If provided, the dummy parameter must be set to the string *, unless running with the -deprecatedrpc=accounts argument (in which case functionality is unchanged).
getbalance	account, minconf and include_watchonly parameters are deprecated, and can only be used if running with '-deprecatedrpc=accounts'
