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

Create a combinerawtransaction RPC which accepts a json array of hex raw
transactions to combine them into one transaction. Signrawtransaction is changed
to no longer combine transactions and only accept one transaction at a time.
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.

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.

1fc8c3d No longer ever reuse keypool indexes (Matt Corallo)
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.

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.

8276e70de Adding assert to avoid a memory access violation inside of PartialMerkleTree::CalcHash() (Chris Stewart)
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).

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.
