Merge #10857: [RPC] Add a deprecation warning to getinfo's output
1c9b818 getinfo deprecation warning (Andrew Chow)

Pull request description:

  This is an alternative to #10841

  This PR implements @gmaxwell's suggestion of a `nag` field for getinfo which warns about the deprecation. Instead of calling it `nag`, I have named it `deprecation-warning`. The output of `getinfo` will look like this:
  ```

  I think this should be tagged for 0.15

Merge #10817: Redefine Dust and add a discard_rate
f4d00e6 Add a discard_rate (Alex Morcos)
b138585 Remove factor of 3 from definition of dust. (Alex Morcos)

Pull request description:

  The definition of dust is redefined to remove the factor of 3.

  Dust is redefined to be the value of an output such that it would
  cost that value in fees to (create and) spend the output at the dust
  relay rate.  The previous definition was that it would cost 1/3 of the
  value.  The default dust relay rate is correspondingly increased to
  3000 sat/kB so the actual default dust output value of 546 satoshis
  for a non-segwit output remains unchanged.  This commit is a refactor
  only unless a dustrelayfee is passed on the commandline in which case
  that number now needs to be increased by a factor of 3 to get the same
  behavior.  -dustrelayfee is a hidden command line option.

  Note: It's not exactly a refactor due to edge case changes in rounding
  as evidenced by the required change to the unit test.

  A discard_rate is added which defaults to 10,000 sat/kB

  Any change output which would be dust at the discard_rate you are
  willing to discard completely and add to fee (as well as continuing to
  pay the fee that would have been needed for creating the change)

  This would be a nice addition for 0.15 and I think will remain useful for 0.16 with the new coin selection algorithms in discussion, but its not crucial.

  It does add translation strings, but we could (should?) avoid that by hiding the option

Merge #10784: Do not allow users to get keys from keypool without reserving them
cf82a9e Do not allow users to get keys from keypool without reserving them (Matt Corallo)

Pull request description:

  fundrawtransaction allows users to add a change output and then
  not have it removed from keypool. While it would be nice to have
  users follow the normal CreateTransaction/CommitTransaction process
  we use internally, there isnt much benefit in exposing this option,
  especially with HD wallets, while there is ample room for users to
  misunderstand or misuse this option.

  This partially reverts #9377. Would be nice to get this for 15 since its kinda crazy we have this option to begin with IMO, will need release notes as an RPC option is now ignored.

fundrawtransaction allows users to add a change output and then
not have it removed from keypool. While it would be nice to have
users follow the normal CreateTransaction/CommitTransaction process
we use internally, there isnt much benefit in exposing this option,
especially with HD wallets, while there is ample room for users to
misunderstand or misuse this option.

This could be particularly nasty in some use-cases (especially
pre-HD-split) - eg a user might fundrawtransaction, then call
getnewaddress, hand out the address for someone to pay them, then
sendrawtransaction. This may result in the user thinking they have
received payment, even though it was really just their own change!

This could obviously result in needless key-reuse.

Pull request description:

  This fixes an issue where you could reserve a keypool entry, then
  top up the keypool, writing out a new key at the given index, then
  return they key from the pool. This isnt likely to cause issues,
  but given there is no reason to ever re-use keypool indexes
  (they're 64 bits...), best to avoid it alltogether.

  Builds on #10235, should probably get a 15 tag.

Merge #10707: Better API for estimatesmartfee RPC
06bcdb8da Convert named argument from nblocks to conf_target (Alex Morcos)
439c4e8ad Improve api to estimatesmartfee (Alex Morcos)

Pull request description:

  Through 0.14 branch, the estimatesmartfee API was tagged "WARNING: This interface is unstable and may disappear or change!" and this warning is removed for 0.15, so any wanted API updates should happen now.

  The changes here are to make the additional parameter for conservative estimates a more general estimate_mode string , to omit the feerate and include an error string instead of returning -1 on error, and to do better parameter checking initially.

  ~It is only the last 2 commits, but it's built on #10706 and #10543~.

  See https://github.com/bitcoin/bitcoin/pull/10707#issuecomment-314869251 for renaming of nblocks argument to conf_target.  Will need to be included before string freeze.

Merge #9980: Fix mem access violation merkleblock

Pull request description:

  Fixing a possible memory access violation in CPartialMerkleTree::CalcHash().

  This can happen if we some how a merkle tree with zero txids. I don't think this can happen in practice as we only send merkle block messages on the p2p network as of now -- we cannot receive them.

  This was found with #8469, specifically using this [generator](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/gen/merkleblock_gen.h#L52-L77) which will cause a memory access violation on [this test case](https://github.com/Christewart/bitcoin/blob/rapidcheck/src/test/merkleblock_properties.cpp#L48).

Merge #10831: Batch flushing operations to the walletdb during top up and increase keypool size.

3a53f19 Pushdown walletdb object through GenerateNewKey/DeriveNewChildKey. (Gregory Maxwell)

Pull request description:

  This carries the walletdb object from top-up through GenerateNewKey/DeriveNewChildKey/CWallet::AddKeyPubKey, which allows us to avoid the flush on destruction until the top up finishes instead of flushing the wallet for every key.

  This speeds up adding keys by well over 10x on my laptop (actually something like 17x), I wouldn't be surprised if it were an even bigger speedup on spinning rust.

  Then it increases the keypool size to 1000. I would have preferred to use 10,000 but in the case where the user creates a new wallet and then turns on encryption it seems kind of dumb to have >400KB of marked-used born unencrypted keys just laying around.

  (Thanks to Matt for cluesticking me on how to bypass the crypter spaghetti)

Merge #10706: Improve wallet fee logic and fix GUI bugs
11590d3 Properly bound check conf_target in wallet RPC calls (Alex Morcos)
fd29d3d Remove checking of mempool min fee from estimateSmartFee. (Alex Morcos)
2fffaa9 Make QT fee displays use GetMinimumFee instead of estimateSmartFee (Alex Morcos)
1983ca6 Use CoinControl to pass custom fee setting from QT. (Alex Morcos)
03ee701 Refactor to use CoinControl in GetMinimumFee and FeeBumper (Alex Morcos)
ecd81df Make CoinControl a required argument to CreateTransaction (Alex Morcos)

Pull request description:

  This builds on #10589  (first 5 commits from that PR, last 5 commits are new)

  The first couple commits refactor to use the CCoinControl class to pass fee calculation parameters around.

  This allows for fixing the buggy interaction in QT between the global payTxFee which can be modified by the RPC call settxfee or temporarily modified by the QT custom fee settings.  Before these changes the GUI could sometimes send a transaction with a recently set payTxFee and not respect the settings displayed in the GUI.   After these changes, using the GUI does not involve the global transaction confirm target or payTxFee.

  The prospective fee displays in the smart fee slider and the coin control dialog are changed to use the fee calculation from GetMinimumFee, this simplifies the code and makes them slightly more correct in edge cases.

  Maxing the fee calculation with the mempool min fee is move from estimateSmartFee to GetMinimumFee.

  This fixes a long standing bug, and should be tagged for 0.15 as it is holding up finalizing the estimatesmartfee RPC API before release.

Merge #10330: [wallet] fix zapwallettxes interaction with persistent mempool
4c3b538 [logs] fix zapwallettxes startup logs (John Newbery)
e7a2181 [wallet] fix zapwallettxes interaction with persistent mempool (John Newbery)
ff7365e [tests] fix flake8 warnings in zapwallettxes.py (John Newbery)

Pull request description:

  zapwallettxes previously did not interact well with persistent mempool.
  zapwallettxes would cause wallet transactions to be zapped, but they
  would then be reloaded from the mempool on startup. This commit softsets
  persistmempool to false if zapwallettxes is enabled so transactions are
  actually zapped.

  This PR also fixes the zapwallettxes.py functional test, which did not properly test this feature. The test line:

  ```py
       assert_raises(JSONRPCException, self.nodes[0].gettransaction, [txid3])
       #there must be a expection because the unconfirmed wallettx0 must be gone by now
  ```
  is not actually testing the presence of the transaction since the RPC is being called incorrectly (with an array instead of a string). The `assert_raises()` passes since an assert is raised, but it's not the one the test writer had in mind!

  Fixes #9710 .

Merge #10739: test: Move variable state down where it is used
5618b7d Do not shadow upper local variable `state`. (Pavel Janík)

Pull request description:

  Tests added in #10192 emit few shadowing warnings:

  ```
  test/txvalidationcache_tests.cpp:268:26: warning: declaration shadows a local variable [-Wshadow]
  test/txvalidationcache_tests.cpp:296:26: warning: declaration shadows a local variable [-Wshadow]
  test/txvalidationcache_tests.cpp:357:26: warning: declaration shadows a local variable [-Wshadow]
  ```

  Remove shadowing declarations and reuse the upper local declaration as in other already present test cases.
