620bae3 Require a steady clock for bench with at least micro precision (Matt Corallo)
Pull request description:
Using a non-steady high_precision_clock by default is definitely not what we want, and in practice steady_clock has more than enough precision. Should double-check that travis passes on this one to make sure we actually have at least microsecond precision on all platforms.

487aff421 Check subtree consistency in Travis (Pieter Wuille)
e1d0cc23a Improve git-subtree-check.sh (Pieter Wuille)
Pull request description:
Apparently many of our subtrees get modified by PRs in this repository, without getting noticed.
To improve upon this:
* Make git-subtree-check.sh capable of doing a weaker consistency check (that doesn't need access to external repositories), but which should be sufficient to detect unintended changes. It can be fooled by a fake subtree merge commit, but that would hopefully be obvious to reviewers.
* Make Travis invoke this subtree check for each of our subtrees.
Note that Travis is currently expected to fail on this PR, as 2 out of 4 subtrees (`src/secp156k1` and `src/univalue` have been modified directly in master).

Nowhere else in the protocol do we send headers which are for

such request (whether for an invalid block or not) in at least two
years of debug.log output, indicating that this should have minimal
impact.

- remove support for alert message
- explicitly don't support p2p versions lower than 60001
Should be an easy ACK for reviewers. If all extended tests pass, then this code really was dead :)

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.

7963335 Fix -disablewallet default value (João Barbosa)
b411c2a Improve -disablewallet parameter interaction (João Barbosa)
Pull request description:
The first commit logs a message for each configured wallet if `-disablewallet` is set:
```
bitcoind -printtoconsole -regtest -disablewallet -wallet=foo -wallet=bar
...
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=foo
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=bar
```
It also moves up the `-disablewallet` check which avoids the unnecessary `-wallet` soft set.
The second commit fixes the default value of `-disablewallet`, currently the value is correct, but it should use `DEFAULT_DISABLE_WALLET`.
The third commit can be dropped or squashed, just took the opportunity to fix the coding style there.

The mininode module includes code to support p2p versions below
60001. However, the test_framework does not support versions
of Bitcoin Core before V0.13.0. Remove code supporting
p2p versions before 60001 (which has never been run).
BIP31 support was added to Bitcoin Core in version 0.6.1. Our test
framework is incompatible with Bitcoin Core versions that old, so remove
all special logic for handling pre-BIP31 pings.

Pull request description:
Final two steps of #10082 : Adding the "mininode" P2P interface to `TestNode`
This PR adds the mininode P2P interface to `TestNode`. It simplifies the process for opening a P2P connection to the node-under-test from this:
```python
node0 = NodeConnCB()
connections = []
connections.append(NodeConn('127.0.0.1', p2p_port(0), self.nodes[0], node0))
node0.add_connection(connections[0])
```
to this:
```python
self.nodes[0].add_p2p_connection(p2p_conn_type=NodeConnCB)
```
The first commit adds the infrastructure to `test_node.py`. The second updates the individual test cases to use it. Can be separated if this is too much review for one PR.

p2p connections can now be added to TestNode instances.
This commit also updates the example test to use the new
p2p interface in TestNode to demonstrate usage.
A future commit will update the existing tests to use p2p through the
TestNode.

5ce7cb9 [net] De-duplicate connection eviction logic (Thomas Snider)
Pull request description:
While reviewing the safeguards against deliberate node isolation on the network by malicious actors, I found a good de-duplication candidate.
I think this form is much more legible (the type of `cutoffs` notwithstanding). ReverseCompareNodeTimeConnected is not included in the list since the cutoff size is a function of the remaining number of nodes in the candidate eviction set.

Pull request description:
gettimeofday has portability issues, see for example #11558.
Regardless of large-scale clock refactors in the future, I think it's fine for bench to just use std::chrono itself.
Note that this may slightly improve bench accuracy and changes the display from tiny floats to nanosecond counts instead.

std::chrono removes portability issues.
Rather than storing doubles, store the untouched time_points. Then
convert to nanoseconds for display. This allows for maximum precision, while
keeping results comparable between differing hardware/operating systems.
Also, display full nanosecond counts rather than sub-second floats.

Pull request description:
Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).
This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.
A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.
This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.
