fa7a6cf1b3 policy: Treat segwit as always active (MarcoFalke)
Pull request description:
Now that segwit is active for a long time, there is no need to reject transactions with the reason that segwit hasn't activated.
Strictly speaking, this is a bug fix, because with the release of 0.16, we create segwit transactions in our wallet by default without checking if they are allowed by local policy.
More broadly, this simplifies the code as if "premature witness" was always set to true with the corresponding command line args.

Pull request description:
When analysing includes in the project it is often assumed that the preferred bracket include syntax (`#include <foo.h>`) mentioned in `developer-docs.md` is used consistently. @sipa:s excellent circular dependencies script [`circular-dependencies.py`](50c69b7801/contrib/devtools/circular-dependencies.py) (#13228) is an example of a script making this reasonable assumption.
This PR enables automatic Travis checking of the include syntax making sure that the bracket syntax includes (`#include <foo.h>`) is used consistently.

0a4ea2f458 build: Add linter for checking accidental locale dependence (practicalswift)
Pull request description:
This linter will check for code accidentally introducing locale dependencies.
Unnecessary locale dependence can cause bugs that are very tricky to isolate and fix. We should avoid using locale dependent functions if possible.
Context: https://github.com/bitcoin/bitcoin/pull/12881#issuecomment-378564722
Example output:
```
$ contrib/devtools/lint-locale-dependence.sh
The locale dependent function tolower(...) appears to be used:
src/init.cpp: if (s[0] == '0' && std::tolower(s[1]) == 'x') {
Unnecessary locale dependence can cause bugs that are very
tricky to isolate and fix. Please avoid using locale dependent
functions if possible.
Advice not applicable in this specific case? Add an exception
by updating the ignore list in contrib/devtools/lint-locale-dependence.sh
```
**Note to reviewers:** What is the most appropriate `LOCALE_DEPENDENT_FUNCTIONS` function list? What should be added or removed?
