Pull request description:
This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.
It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).
For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).
Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.
Example: a node has four outputs linked to two addresses `A` and `B`:
* 1.0 btc to `A`
* 0.5 btc to `A`
* 1.0 btc to `B`
* 0.5 btc to `B`
The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
* 0.5 btc to `A` or `B` is picked
* 0.2 btc is output to `C`
* 0.3 - fee is output to (unique change address)
With `-avoidpartialspends`, the following will instead happen:
* Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
* 0.2 btc is output to `C`
* 1.3 - fee is output to (unique change address)
As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.
This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.
Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

64b9f27e0e Skip is_closing() check when not available. (Daniel Kraft)
Pull request description:
#13715 introduced a new check for `_transport.is_closing()` in mininode's `P2PConnection`'s. This function is [only available from Python 3.4.4](https://docs.python.org/3.4/library/asyncio-protocol.html#asyncio.BaseTransport.is_closing), though, while Bitcoin Core is supposed to support all Python 3.4 versions.
In this change, we make the check conditional on `is_closing` being available. If it is not, then we revert to the behaviour before the check was introduced; this means that #13579 is not fixed for old systems, but at least the tests work as they used to do before.
This includes a small refactoring from a one-line lambda to an inline function, because this makes the code easier to read with more and more conditions being added.
Fixes#13745.

793290f940 Net: Fixed a race condition when disabling the network. (lmanners)
Pull request description:
This change addresses a race condition where setnetworkactive=false wouldn't always disconnect all peers.
Before this change, the following could happen:
1. Thread A -- Begins connecting to a node.
2. Thread B -- Sets kNetworkActive=false and disconnects connected nodes.
3. Thread A -- Finishes connecting and adds node to list of connected nodes.
The node that was connected from Thread A remains connected and active,
even though kNetworkActive=false.
To fix the race, disconnections when kNetworkActive=false are now handled in the main network loop.

ac8a1d092e [RPC] Remove field in getblocktemplate help that has never been used (Conor Scott)
Pull request description:
[BIP 22 - getblocktemplate](https://github.com/bitcoin/bips/blob/master/bip-0022.mediawiki#Transactions%20Object%20Format) specifies an optional flag, `required` if the transaction must be in the block.
Luke's implementation #936 did not include this flag, and it was later added to the help description in #3246 (more than a year later) but the field was still never actually implemented. As far as I can tell, bitcoin core would have never actually included this in a `getblocktemplate` call, so it seems logical to remove it from the help description.
If I am missing something or this is considered harmless - I can close the PR.

This commit contains 2 refactors.
1. mark "const" on ArgsManager::GetHelpMessage and IsArgKnown.
2. remove unused "error" argument from ArgsManager::IsArgKnown.
Firstly, I mark "const" on where it is possible to. It is mentioned
before (e.g. https://github.com/bitcoin/bitcoin/pull/13190#pullrequestreview-118823133).
And about 2nd change, ArgsManager::IsArgKnown was added at commit #4f8704d which was
merged at PR #13112. But from its beggining, "error" argument never be used.
I think it should be refactored.

Pull request description:
This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.
Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.
This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

Pull request description:
Add error handling. Check return value of `ParseUInt32(...)` in `ParseHDKeypath(...)`.
`ParseUInt32(...)` returns `false` if the entire string could not be parsed or when an overflow or underflow occurred. In such case the uninitialized variable `number` would be used in the calculation of `path` (prior to this commit).
An example key path triggering this is `m/0/4294967296`:
```
ParseHDKeypath("m/0/4294967296", keypath);
```
`4294967296` is `1` + `0xFFFFFFFF` (`uint32_t` max: `4294967295`).
