This introduces internal types:
* CKeyID: reference (hash160) of a key
* CScriptID: reference (hash160) of a script
* CTxDestination: a boost::variant of the former two
CBitcoinAddress is retrofitted to be a Base58 encoding of a
CTxDestination. This allows all internal code to only use the
internal types, and only have RPC and GUI depend on the base58 code.
Furthermore, the header dependencies are a lot saner now. base58.h is
at the top (right below rpc and gui) instead of at the bottom. For the
rest: wallet -> script -> keystore -> key. Only keystore still requires
a forward declaration of CScript. Solving that would require splitting
script into two layers.
Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed.
This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart.
The following notifications were added:
- `NotifyBlocksChanged`: Block chain changed
- `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed.
- `NotifyAddressBookChanged`: Address book entry changed.
- `NotifyTransactionChanged`: Wallet transaction added, removed or updated.
- `NotifyNumConnectionsChanged`: Number of connections changed.
- `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification.
These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp).
Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.
When a transaction has multiple outputs that go to the wallet, list these
as multiple transactions in the UI. This is also applied to generated
(coinbase) transactions. Also makes the code shorter and easier
to understand.
- Also, prepare for OP_EVAL by calling all transactions without bitcoin address "SendToOther"/"RecvFromOther",
(IP tx'es are so rare they can be put together with funky EV_EVAL scripts)
