Pull request description:
This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).
Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.
To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).
As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

* llmq|init|test: Add "mode" to -llmq-qvvec-sync parameter
This changes the paramter from `-llmq-qvvec-sync=<quorum_name>` to `-llmq-qvvec-sync=<quorum_name:mode>`
With the following definitions:
- `quorum_name`: Internal name of the quorum type
- `mode=0` - Sync always from all quorums of the type defined by `quorum_name`
- `mode=1` - Sync only if member of any from all other quorum of the type defined by `quorum_name`
`-llmq-qvvec-sync=llmq_100_67:0` To always request qvvec's from all `LLMQ_100_67`.
`-llmq-qvvec-sync=llmq_100_67:1` Only request if type member.
This means, if platform enables this on all MNs with `mode=0` we will
have all nodes asking new quorum for their verification vector instead
of only `24*100` at max.

ed82f1700006830b6fe34572b66245c1487ccd29 have verifytxoutproof check the number of txns in proof structure (Gregory Sanders)
Pull request description:
Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/
This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.
The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

`importprunedfunds` needs this check as well. Can expand it to cover this if people like the idea.

Pull request description:
This gets rid of some non-type safe string comparisons and access to members that are implementation details of `class P2PConnection(asyncore.dispatcher)`. Such refactoring is required to replace the deprecated asyncore with something more sane.
Changes:
* Get rid of non-enum member `state` and replace is with bool `connected`
* Get rid of confusing argument `pushbuf` and literally just push to the buffer at the call site

c8330d4 qa: Use node.datadir instead of tmpdir in test framework (MarcoFalke)
Pull request description:
Commit c53c9831ee introduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir.
This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.

Beside removing duplicates of the same args in the code, this actually helps with debugging after a test failure.
For example, `bitcoin-qt` has `server` turned off, so you'd have to turn it on every time, if you wanted to debug a temporary test datadir created by the test framework.
Also, `keypool` would fill up if you forget to specify `-keypool=1`.

eefff65a4b scripted-diff: change signrawtransaction to signrawtransactionwithwallet in tests (Andrew Chow)
1e79c055cd Split signrawtransaction into wallet and non-wallet (Andrew Chow)
Pull request description:
This PR is part of #10570. It also builds on top of #10571.
This PR splits `signrawtransaction` into two commands, `signrawtransactionwithkey` and `signrawtransactionwithwallet`. `signrawtransactionwithkey` requires private keys to be passed in and does not use the wallet for any signing. `signrawtransactionwithwallet` uses the wallet to sign a raw transaction and does not have any parameters to take private keys.
The `signrawtransaction` RPC has been marked as deprecated and will call the appropriate RPC command based upon the parameters given. A test was added to check this behavior is still consistent with the original behavior.
All tests that used `signrawtransaction` have been updated to use one of the two new RPCs. Most uses were changed to `signrawtransactionwithwallet`. These were changed via a scripted diff.

Pull request description:
Extracted from #12379, because the changes are important on their own.
This allows for exact testing, since the match can be specified with a strict regex. Internal details (such as exact formatting of the error message) can still be fuzzed away by regex wildcards.

89fe5feea2 [tests] Stop feature_block.py from blowing up memory. (John Newbery)
Pull request description:
The new P2PDataStore class was sending full blocks in headers messages,
which meant that calls to send_blocks_and_test() would blow up memory if
called with a large number of blocks. Fix that by only sending headers
in headers messages.
This means that python should use just over 1GB for feature_block.py (with bitcoind also using just over 1GB). That's the same as before the feature_block.py refactor.
