5a5e4e9 [wallet] Remove CTransaction&() helper conversion operator from wallet implementation. (Karl-Johan Alm)
Pull request description:
The `CTransaction&()` operator in `CMerkleTx` makes conversion into `CTransaction`s transparent, but was marked as to-be-removed in favor of explicitly getting the `tx` ivar, presumably as the operator can lead to ambiguous behavior and makes the code harder to follow.
This PR removes the operator and adapts callers. This includes some cases of `static_cast<CTransaction>(wtx)` → `*wtx.tx`, which is definitely an improvement.

This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.
Thanks to @morcos for the suggestion to do this.
Note that there are several race conditions introduced here:
* If a user calls sendrawtransaction from RPC, adding a
transaction which is "trusted" (ie from them) and pays them
change, it may not be immediately used by coin selection until
the notification callbacks finish running. No such race is
introduced in normal transaction-sending RPCs as this case is
explicitly handled.
* Until Block{Connected,Disconnected} and
TransactionAddedToMempool calls also run in the CSceduler
background thread, there is a race where
TransactionAddedToMempool might be called after a
Block{Connected,Disconnected} call happens.
* Wallet will write a new best chain from the SetBestChain
callback prior to having processed the transaction from that
block.
[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."

This blocks until the wallet has synced up to the current height.

0b1b9148c Remove countMaskInv caching in bench framework (Matt Corallo)
Pull request description:
This fixes an issue where estimatesmartfee which matches at the min relay fee will return 999 sat/byte instead of 1000 sat/byte due to a float rounding issue. I went ahead and made all float <-> int conversion outside of test/qt explicit (test only had one or two more, Qt had quite a few, including many in the Qt headers themselves) and added overloads to CFeeRate to force callers to do an explicit round themselves. Easy to test with -Wfloat-conversion.

fd849e1b0 Change AcceptToMemoryPool function signature (Alex Morcos)
Pull request description:
First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.
Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)
Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

Pull request description:
Builds on top of #11117.
This adds support for:
* Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
* Sending to BIP173 addresses (including non-v0 ones)
* Analysing BIP173 addresses (through `validateaddress`)
It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.
Not included (and intended for other PRs):
* Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
* Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
* Error locating in UI for BIP173 addresses.

Combine fLimitFree and fOverrideMempoolLimit into a single boolean:
bypass_limits. This is used to indicate that mempool limiting based on feerate
should be bypassed. It is used when readding transactions from a reorg and then
the mempool is trimmed to size after all transactions are added and they can be
evaluated in the context of their descendants. No changes to behavior.

de9a1db Acquire cs_main lock before cs_wallet during wallet initialization (Russell Yanofsky)

6af49dd Output a bit more information for fee calculation report. (Alex Morcos)
a54c7b9 Fix rounding errors in calculation of minimum change size (Alex Morcos)
Pull request description:
Thanks to @juscamarena for reporting this.
Please backport to 0.15.
There was a potential rounding error where the fee for the change added to the fee for the original tx could be less than the fee for the tx including change.
This is fixed in the first commit. The second commit adds one more snippet of information in the fee calculation report. I actually realized that there is more information that would be nice to report, but we can add that post 0.15.
An open question is whether we should be returning failure if the test in line 2885 is hit or just resetting pick_new_inputs and continuing. Originally I made it a failure to avoid any possible infinite loops. But the case hit here is an example of where that logic possibly backfired.

f01103c MOVEONLY: Init functions wallet/wallet.cpp -> wallet/init.cpp (Russell Yanofsky)
e7fe320 MOVEONLY: Fee functions wallet/wallet.cpp -> wallet/fees.cpp (Russell Yanofsky)
d97fe20 Move some static functions out of wallet.h/cpp (Russell Yanofsky)
Pull request description:
This just moves some static wallet fee and init functions out of `wallet/wallet.cpp` and into new `wallet/fees.cpp` and `wallet/init.cpp` source files. There is one commit updating declarations and callers, followed by two MOVEONLY commits actually moving the function bodies.
This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization.
Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

CWallet::MarkConflicted may acquire the cs_main lock after
CWalletDB::LoadWallet acquires the cs_wallet lock during wallet initialization.
(CWalletDB::LoadWallet calls ReadKeyValue which calls CWallet::LoadToWallet
which calls CWallet::MarkConflicted). This is the opposite order that cs_main

POTENTIAL DEADLOCK DETECTED errors if bitcoin is built with -DDEBUG_LOCKORDER.
This commit changes CWallet::LoadWallet (which calls CWalletDB::LoadWallet) to

acquiring wallet and main locks out of order and failed with the new locking in
CWallet::LoadWallet.

e53615b Remove vchDefaultKey and have better first run detection (Andrew Chow)
Pull request description:
Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database.
This also fixes a (rather contrived) case where an encrypted non-HD wallet has corruption such that the default key is no longer valid and is loaded into a Core version that supports HD wallets. This causes a runtime exception since a new hd master key is generated as the software believes the wallet file is newly created but cannot add the generated key to the wallet since it is encrypted. I was only able to replicate this error by creating a non-hd wallet, encrypting it, then editing the wallet using `db_dump` and `db_load` before loading the wallet with hd enabled. This problem has been reported by [two](https://bitcointalk.org/index.php?topic=1993244.0) [users](https://bitcointalk.org/index.php?topic=1746976.msg17511261#msg17511261) so it is something that can happen, although that raises the question of "what corrupted the default key".

Removes vchDefaultKey which was only used for first run detection.
Improves wallet first run detection by checking to see if any keys
were read from the database.
This will now also check for a valid defaultkey for backwards
compatibility reasons and to check for any corruption.
Keys will stil be generated on the first one, but there won't be
any shown in the address book as was previously done.
