Split up util.cpp/h into:
- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)
The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).
Breaks dependency of sha256.cpp on all the things pulled in by util.
An user on IRC reported an issue where `getrawchangeaddress`
keeps returning a single address when the keypool is exhausted.
In my opinion this is strange behaviour.
- Change CReserveKey to fail when running out of keys in the keypool.
- Make `getrawchangeaddress` return RPC_WALLET_KEYPOOL_RAN_OUT when
unable to create an address.
- Add a Python RPC test for checking the keypool behaviour in combination
with encrypted wallets.
- add a small wrapper in util around RAND_bytes() and replace with
GetRandBytes() in the code to log errors from calling RAND_bytes()
- remove OpenSSL header rand.h where no longer needed
Get rid of SendMoney and replace it by the functionality of
SendMoneyToDestination. This cleans up the code, since only
SendMoneyToDestination was actually used (SendMoney internally from this
routine).
The wallet now uses the mempool fee estimator with a new
command-line option: -txconfirmtarget (default: 1) instead
of using hard-coded fees or priorities.
A new bitcoind that hasn't seen enough transactions to estimate
will fall back to the old hard-coded minimum priority or
transaction fee.
-paytxfee option overrides -txconfirmtarget.
Relaying and mining code isn't changed.
For Qt, the coin control dialog now uses priority estimates to
label transaction priority (instead of hard-coded constants);
unspent outputs were consistently labeled with a much higher
priority than is justified by the free transactions actually
being accepted into blocks.
I did not implement any GUI for setting -txconfirmtarget; I would
suggest getting rid of the "Pay transaction fee" GUI and replace
it with either "target number of confirmations" or maybe
a "faster confirmation <--> lower fee" slider or select box.
This changes the keystore data format, wallet format and IsMine logic
to detect watch-only outputs based on direct script matching rather
than first trying to convert outputs to destinations (addresses).
The reason is that we don't know how the software that has the spending
keys works. It may support the same types of scripts as us, but that is
not guaranteed. Furthermore, it removes the ambiguity between addresses
used as identifiers for output scripts or identifiers for public keys.
One practical implication is that adding a normal pay-to-pubkey-hash
address via importaddress will not cause payments to the corresponding
full public key to be detected as IsMine. If that is wanted, add those
scripts directly (importaddress now also accepts any hex-encoded script).

Changes:
* Add Add/Have WatchOnly methods to CKeyStore, and implementations
in CBasicKeyStore.
* Add similar methods to CWallet, and support entries for it in
CWalletDB.
* Make IsMine in script/wallet return a new enum 'isminetype',
rather than a boolean. This allows distinguishing between
spendable and unspendable coins.
* Add a field fSpendable to COutput (GetAvailableCoins' return type).
* Mark watchonly coins in listunspent as 'watchonly': true.
* Add 'watchonly' to validateaddress, suppressing script/pubkey/...
in this case.

-respendnotify=<cmd> Execute command when a network tx respends wallet
tx input (%s=respend TxID, %t=wallet TxID)
Add respendsobserved array to gettransaction, listtransactions, and
listsinceblock RPCs. This omits the malleated clones that are included
in the walletconflicts array.
Add RPC help for respendsobserved and walletconflicts (help was missing
for the latter).
Respend transactions that conflict with transactions already in the
wallet are added to it. They are not displayed unless they also involve
the wallet, or get into a block. If they do not involve the wallet,
they continue not to affect balance.
Transactions that involve the wallet, and have conflicting non-equivalent
transactions, are highlighted in red. When the conflict first occurs, a
modal dialog is thrown.
CWallet::SyncMetaData is changed to sync only to equivalent transactions.
When a conflict is added to the wallet, counter nConflictsReceived is
incremented. This acts like a change in active block height for the
purpose of triggering UI updates.
Use CFeeRate instead of an int64_t for quantities that are
fee-per-size.
Helps prevent unit-conversion mismatches between the wallet,
relaying, and mining code.
Size specifiers are no longer needed now that we use typesafe tinyformat
for string formatting, instead of the system's sprintf.
No functional changes.
This continues the work in #3735.
- In wallet and GUI code LOCK cs_main as well as cs_wallet when
necessary
- In main.cpp SendMessages move the TRY_LOCK(cs_main) up, to encompass the call
to IsInitialBlockDownload.
- Make ActivateBestChain, AddToBlockIndex, IsInitialBlockDownload,
InitBlockIndex acquire the cs_main lock
Fixes#3997
Now that AddToWallet is called when loading transactions from the
wallet database, BindWallet can be integrated into that and does not
need to be an extra step.
Leaves behaviour unchanged, but makes the
fFromLoadWallet/!fFromLoadWallet paths in AddToWallet a bit more
symmetric.
