b191c7dfb7 doc: add comment explaining recentRejects-DoS behavior (James O'Beirne)
Pull request description:
When we receive invalid txs for the first time, we mark the sender as
misbehaving. If we receive the same tx before a new block is seen, we *don't*
punish the second sender (in the same way we do the original sender). It wasn't
initially clear to me that this is intentional, so add a clarifying comment.

c82190cdb6 tests: Add Python dead code linter (vulture) (practicalswift)
590a57fdec tests: Remove unused testing code (practicalswift)
Pull request description:
Add Python dead code linter (`vulture`) to Travis.
Rationale for allowing dead code only after explicit opt-in (via `--ignore-names`):
* Less is more :-)
* Unused code is by definition "untested"
* Unused code can be an indication of bugs/logical errors. By making the contributor aware of newly introduced unused code it gives him/her an opportunity to investigate if the unused code they introduce is malignant or benign :-)
* Unused code is hard to spot for humans and is thus often missed during manual review
* [YAGNI](https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it)
Based on #14312 to make linter job pass.

Pull request description:
Switches to named constants, because numeric_limits calls can be harder to read and less portable.
Change was suggested by jamesob in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r213473620
There are no changes in behavior except on some platforms we don't support (ILP64, IP16L32, I16LP32), where `SignalsOptInRBF` and `MutateTxAddInput` functions would now work correctly.

Pull request description:
- decrease clone depth to 5
- Upgrade to python 3.7 that we can use `PYTHONUTF8` from PEP540.
- Set clcache version to `v4.2.0`
- Do not fetch the latest vcpkg package (The issue does not exist anymore)
- Set test_bitcoin report sink and log sink to stdout and redirect stderr to NUL to drop confusing error messages that introduced by #14146
- discard vcpkg, bench_bitcoin output
- Set functional test `--failfast` flag
- Make the log be as clear as possible. (Only ~100 lines)

Pull request description:
Fail the UBSan Travis build in case of newly introduced [UBSan (UndefinedBehaviorSanitizer)](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html) errors.
Prior to this commit new UBSan errors were printed but didn't fail the UBSan Travis build.
Changes:
* Travis: Add UBSan options: `print_stacktrace` + `halt_on_error`
* Travis: Add UBSan suppressions needed to pass test suite
* Travis: Add `llvm-symbolizer` directory to PATH. Needed to get symbolized stack traces from the sanitizers.
`halt_on_error` should have been part of #14252 really :-)

5a05aa2db2 Add metavar to match var name in help text + Change wording for better readability (Martin Erlandsson)
Pull request description:
The help text given by `test/functional/test_runner.py -h` refers to the value `n`, which is defined as `COMBINEDLOGSLEN` in the list of commands.
To make the help text consistent, this PR changes the display name `COMBINEDLOGSLEN` to `n` by setting the argparse [`metavar`](https://docs.python.org/3/library/argparse.html#metavar) attribute. (`metavar` only changes the _displayed_ name)
Alternatively: Do the opposite and change the help text to use `COMBINEDLOGSLEN`.
---
Before PR:
```
➜ bitcoin > test/functional/test_runner.py -h | grep -A 1 combinedlogslen
--combinedlogslen COMBINEDLOGSLEN, -c COMBINEDLOGSLEN
print a combined log (of length n lines) from all test nodes and test framework to the console on failure.
```
After PR:
```
➜ bitcoin > test/functional/test_runner.py -h | grep -A 1 combinedlogslen
--combinedlogslen n, -c n
print a combined log (of length n lines) from all test nodes and test frameworks to the console on failure.
```

Also, fixed pluralization typo.

Route calls during node initialization and shutdown that would happen between a
node process and wallet processes through the serializable `Chain::Client`
interface, rather than `WalletInitInterface` which is now simpler and only
deals with early initialization and parameter interaction.
This commit mostly does not change behavior. The only change is that the
"Wallet disabled!" and "No wallet support compiled in!" messages are now logged
earlier during startup.

fef5adcc33 blockfilter: Use unordered_set instead of set in blockfilter. (Jim Posen)
4fb789e9b2 Extract CSipHasher to it's own file in crypto/ directory. (Jim Posen)
Pull request description:
Use `std::unordered_set` (hash set) instead of `std::set` (tree set) in blockfilter interface, as suggested by @ryanofsky in #12254. This may result in a very minor speedup, but I haven't measured.
This moves `CSipHasher` to it's own file `crypto/siphash.h`, so that it can be used in the libbitcoin_util library without including `hash.{h,cpp}`. I'm open to other suggestions on solving this issue if people would prefer to leave CSipHasher where it is.

Pull request description:
- Adds `p2p_invalid_messages.py`: tests based on behavior for dealing with invalid and malformed P2P messages. Includes a test verifying that we can't DoS a node by spamming it with large invalid messages.
- Adds `TestNode.assert_memory_usage_stable`: a context manager that allows us to ensure memory usage doesn't significantly increase on a node during some test.
- Adds `P2PConnection.send_raw_message`: which allows us to construct and send messages with tweaked headers.

This is a refactoring change that doesn't affect behavior. The motivation
behind the change is give BerkeleyEnvironment objects access to
BerkeleyDatabase objects so it will be possible to simplify the duplicate
wallet check and more reliably avoid opening the same databases twice.

Pull request description:
Run functional tests and benchmarks under the undefined behaviour sanitizer (UBSan).
This will make Travis automatically detect issues such as:
* #14242: Avoid triggering undefined behaviour (`std::memset(nullptr, 0, 0)`) if an invalid string is passed to `DecodeSecret(...)`
* #14239: Avoid dividing by zero (undefined behaviour) in `EstimateMedianVal` (policy)/`ConnectTip` (validation)/`CreateTransaction` (wallet)
* #13546: wallet: Avoid potential use of uninitialized value `bnb_used` in `CWallet::CreateTransaction(...)`
Addresses issue #14059.
