This moves the following policy settings functions and globals to a new
src/policy/settings unit in lib_server:
- `incrementalRelayFee`
- `dustRelayFee`
- `nBytesPerSigOp`
- `fIsBareMultisigStd`
These settings are only required by the node and should not be accessed
by other libraries.
21be609b49 In lint-format-strings, open files sequentially (Glenn Willen)
Pull request description:
In lint-format-strings, we use python argparse to read our file arguments. In
this mode, argparse opens all the files simultaneously. On OS X, where the
default filehandle limit is 128, this causes the lint to fail. Instead, ask
argparse for our filename arguments as strings, and open them one at a time
using 'with open'.

**Notes for reviewers**
1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

fdf82ba18 Update all subprocess.check_output functions in CI scripts to be Python 3.4 compatible (Graham Krizek)
Pull request description:
CI is failing the `lint` stage on every Cron run (regular PR/Push runs still pass). The failure was introduced in 74ce326 and has been broken since. The Python version running in CI was downgraded to 3.4 from 3.6. There were a couple files that were using the `encoding` argument in the `subprocess.check_output` function. This was introduced in Python 3.6 and therefore broke the scripts that were using it. The `universal_newlines` argument was used as well, but in order to use it we must be able to set encoding because of issues on some BSD systems.
To get CI to pass, I removed all `universal_newline` and `encoding` args to the `check_ouput` function. Then I decoded all `check_output` return values. This should keep the same behavior but be Python 3.4 compatible.

Introduces `TestNode.profile_with_perf()` context manager which
samples node execution to produce profiling data.
Also introduces a test framework flag, `--perf`, which will run
perf on all nodes for the duration of a given test.
Removing the 'universal_newlines' and 'encoding' args from the subprocess.check_outputs fuction. 'universal_newlines' is supported in 3.4, but 'encoding' is not. Without specifying 'encoding' it will make a guess at encoding, which can break things on BSD systems. We must handle encoding/decoding ourselves until we can use Python 3.6

59e387705c test: add invalid tx templates for use in functional tests (James O'Beirne)
Pull request description:
This change adds a list of `CTransaction`-generating templates which each correspond to a specific type of invalid transaction. We then use this list to test for a wider variety of invalid tx types in `p2p_invalid_tx.py` and `feature_block.py`.
Consolidating all invalid tx types will allow us to more easily cover all tx reject cases from a variety of tests without repeating ourselves. Validation logic doesn't differ much between mempool and block acceptance, but there *is* a difference and we should be sure we're testing both comprehensively.
Right now, I've only added templates covering the tx reject types listed below but if this approach seems worthwhile I will expand the list to be fully comprehensive.

Pull request description:
Advantages of this change:
- avoid resolving wallet absolute path and name repetitively and in multiple places;
- avoid calling `GetWalletDir` in multiple places;
- extract these details from the actual wallet implementation.
The `WalletLocation` class can be a way to represent a wallet not yet loaded that exists in the wallet directory.

854c85ae90 test: allow arguments to be forwarded to flake8 in lint-python.sh (James O'Beirne)
Pull request description:
In order to use `lint-python.sh` from within various in-editor linting frameworks (e.g. [ALE](https://github.com/w0rp/ale), [flycheck](https://github.com/flycheck/flycheck)), we need to allow its arguments to be forwarded to the wrapped flake8 invocation.
For what it's worth, here's my bitcoin-specific ALE vim config for doing so (requires this changeset):
