New getnodeaddresses call gives access via RPC to the peers known by
the node. It may be useful for bitcoin wallets to broadcast their
transactions over tor for improved privacy without using the
centralized DNS seeds. getnodeaddresses is very similar to the getaddr
p2p method.
Tests the new rpc call by feeding IP address to a test node via the p2p
protocol, then obtaining someone of those addresses with
getnodeaddresses and checking that they are a subset.

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.

Pull request description:
Currently the functional tests require the wallet module to be compiled into the Bitcoin Core executable. For example the premine (or datadir cache) to speed up tests when run in parallel would mine a bunch of blocks and store the private keys to sign the coinbase tx outputs in a wallet. There is no need to have the overhead of the whole wallet module by using keys that are deterministic for all runs.
Note that this change most likely requires the `./test/cache/` to be cleared.

fa6ab8ada1 rpc: Return more specific reject reason for submitblock (MarcoFalke)
Pull request description:
The second commit in #13439 made the `TODO` in the first commit impossible to solve.
The meaning of `fNewBlock` changed from "This is the first time we process this block" to "We are about to write the new *valid* block".
So whenever `fNewBlock` is true, the block was valid. And whenever the `fNewBlock` is false, the block is either valid or invalid. If it was valid and not new, we know it is a `"duplicate"`. In all other cases, the `BIP22ValidationResult()` will return the reason why it is invalid.

This PR contains the changes needed to make `lint-all.sh` run as expected.
Ideally the linters would continuously run also under a Travis macOS environment to make sure we catch these kind of issues before merge.

Don't `assert(...)` with side effects.
From the developer notes:
> **Assertions should not have side-effects**
>
> Rationale: Even though the source code is set to refuse to compile with assertions disabled, having side-effects in assertions is unexpected and makes the code harder to understand
These assertions were introduced quite recently (in #14069 which was merged two days ago) and since this is a recurring thing (see #13534 – "Don't assert(foo()) where foo() has side effects" from May) I added a simple regression test for the most obvious common side effect.

7a208d9fad Implements custom tolower and toupper functions. (251)
e2ba043b8d Implements ParseNetwork unit test. (251)
Pull request description:
This pull request removes the `boost/algorithm/string/case_conv.hpp` dependency from the project.
`boost/algorithm/string/case_conv.hpp` is included for the `boost::to_lower` and `boost::to_upper` template functions.
We can replace the calls to these functions with straightforward alternative implementations that use the C++ Standard Library, because the functions are called with `std::string` objects that use standard 7-bit ASCII characters as argument.
The refactored implementation should work without the explicit `static_cast<unsigned char>` cast and `unsigned char` lambda return type. Both have been added defensively and to be explicit. Especially in case of the former, behaviour is undefined (potentially result in a crash) if the `std::toupper` argument is not an `unsigned char`.
A potential alternative, maybe even preferred, implementation to address the `boost::to_lower` function call in `ParseNetwork(std::string)` could have been:
```c++
if (net == "ipv4" || net == "IPv4") return NET_IPV4;
if (net == "ipv6" || net == "IPv6") return NET_IPV6;
```
This alternative implementation would however change the external behaviour of `ParseNetwork(std::string)`.
This pull requests includes a unit test to validate the implementation of `ParseNetwork(std::string)` prior and after the removal of the `case_conv.hpp` dependency.
`boost/algorithm/string/case_conv.hpp` has been removed from the `EXPECTED_BOOST_INCLUDES` in `test/lint/lint-includes.sh` because it is no longer required.

Pull request description:
This pull request adds a flag "bip125-replaceable" to the mempool RPCs getrawmempool, getmempoolentry, getmempoolancestors and getmempooldescendants, which indicates whether an unconfirmed transaction might be replaced.
Initially the flag was added to the raw transaction RPCs, but thanks to @conscott, it was moved to the mempool RPCs, which actually have access to the mempool.
~~This pull request adds a flag "bip125-replaceable" to the RPCs "getrawtransaction" and "decoderawtransaction", which indicates, whether a transaction signals BIP 125 replaceability.~~
There was some discussion in #7817, whether showing replaceability in the UI could lead to the false assumption that transactions that don't signal BIP 125 are truely non-replaceable, but given that this PR tackles the raw transaction interface, which is a rather low level tool, I believe having this extra piece of information isn't bad.

Fix this by refusing to sign if there is any mismatch between the provided data and what is being signed.

bd19cc78cf Serialize non-witness utxo as a non-witness tx but always deserialize as witness (Andrew Chow)
43811e6338 Fix PSBT deserialization of 0-input transactions (Andrew Chow)
Pull request description:
0-input transactions can be ambiguously deserialized as being witness transactions. Since the unsigned transaction is never serialized as a witness transaction as it has no witnesses, we should always deserialize it as a non-witness transaction and set the serialization flags as such.
When a transaction is serliazed for the non-witness-utxo, it is always a valid network transaction and thus it should be always be deserialized as a witness transaction and the deserialzation flags are set as such.
Fixes#13958

0-input transactions can be ambiguously deserialized as being witness
transactions. Since the unsigned transaction is never serialized as
a witness transaction as it has no witnesses, we should always
deserialize it as a non-witness transaction and set the serialization
flags as such.
Also always serialize the unsigned transaction as a non-witness transaction.
68400d8b96 tests: Use explicit imports (practicalswift)
Pull request description:
Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.
Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.
An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Since #13669 changed some signatures, I think it might be worthwhile to enforce named args for primitive types such as amounts.

4b7091a842 Replace median fee rate with feerate percentiles (Marcin Jachymiak)
Pull request description:
Currently, the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.
This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

Pull request description:
### qa: Close stdout and stderr file when node stops
Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.
Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)
### qa: Run gen_rpcauth with sys.executable
Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)
### qa: Use files for stdout/stderr to support Windows
It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.
