Pull request description:
This PR adds binaries for 0.17, 0.18 and 0.19 to Travis and runs a basic block propagation test.
Includes test for upgrading v0.17.1 wallets and opening master wallets with older versions.
Usage:
```sh
contrib/devtools/previous_release.sh -f -b v0.19.0.1 v0.18.1 v0.17.1
test/functional/backwards_compatibility.py
```
Travis caches these earlier releases, so it should be able to run these tests with little performance impact.
Additional scenarios where it might be useful to run tests against earlier releases:
* creating a wallet with #11403's segwit implementation, copying it to an older node and making sure the user didn't lose any funds (although this PR doesn't support `v0.15.1`)
* future consensus changes
* P2P changes (e.g. to make sure we don't accidentally ban old nodes)
