Pull request description:
This corrects all violations of `-Wzero-as-null-pointer-constant` identified in the Qt codebase.
These changes are extracted from #15112 as suggested by @MarcoFalke to ease review. This is in service of enabling `-Wzero-as-null-pointer-constant`, which should eliminate this as a concern going forward.
Note there are 2 non-Qt changes: `src/test/allocator_tests.cpp` and `src/wallet/db.cpp`.

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

Pull request description:
Two cleanups in `util/strencodings.h`:
- Remove `[U](BEGIN|END)` macros — The only use of these was in the Merkle tree code with `uint256` which has its own `begin` and `end` methods which are better.
- Make ToLower and ToUpper take a char — Unfortunately, `std::string` elements are (bare) chars. As these are the most likely type to be passed to these functions, make them use char instead of unsigned char. This avoids some casts.

fa5a6ce102 qa: Raise ci test_runner timeout to 40 mins (MarcoFalke)
fa3df025e1 travis: Avoid timeout on verify-commits check (MarcoFalke)
Pull request description:
The verify-commits check is too expensive to run in full (calculate Tree-SHA512 and clean-merge for every single merge commit in history) every day (the cron job runs every ~24h). Since the cron job is running every day, it is also redundant to redo most of the work on the next day.
So, only check two days worth of commits and assume that travis checked the Tree-SHA512 and clean-merge for all other commits already. The script will still check all the signatures, since the check-result for them depends on external inputs such as current time or the public keys we got from the server.
[Note that travis is not meant to do the verification for anyone or is meant to be trusted in any way. This check only serves as a belt-and-suspender to notify maintainers in case of a technical issue or script malfunction. But since the script is timing out for months now, its purpose is diminished right now.]

fa21568208 qa: Avoid race in p2p_invalid_block by waiting for the block request (MarcoFalke)
6c787d340c tests: Make feature_block pass on centos (MarcoFalke)
Pull request description:
This hopefully fixes#14661, which I believe is caused by a race in `send_blocks_and_test`. By setting `request_block=False` we only effectively check `node.getbestblockhash() != blocks[-1].hash` before returning and checking the debug.log. By setting `request_block=True` (the default) we make sure that we send the block, then sync with a ping before asserting on the debug.log.
Even if this patch doesn't fix the issue, it is good cleanup: There is no reason to not wait for the blocks to be requested, since in all these cases the header gives no indication that the block is consensus invalid. So this patch makes the test also a bit stricter and more useful.
Unrelated to this, I also include a fix that makes the tests pass on latest CentOS.

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.

c8d9d9093b Fix broken notificator on GNOME (Hennadii Stepanov)
Pull request description:
Fix#14994; that bug was introduced in #14228 (that was my fault).
~Also this commit explicit separates~ There are two functions of the tray icon:
- a system tray widget (`QSystemTrayIcon::isSystemTrayAvailable() == true`)
- a high-level notificator via balloon messages (`QSystemTrayIcon::supportsMessages() == true`)
~These properties are mutually independent,~ e.g., on Fedora 29 + GNOME:
```
QSystemTrayIcon::isSystemTrayAvailable() == false;
QSystemTrayIcon::supportsMessages() == true;
```
UPDATE:
`supportsMessages()` makes no sense without `isSystemTrayAvailable()`: `QSystemTrayIcon::showMessage()` just not working on Fedora 29 + GNOME.

This is a bugfix, since wallet_dump currently uses the wrong name:

Rename all to the same name with a scripted diff (and some unrelated cleanups).

ae5594d51b489826f2f2315c92e8df5ee0267efc [Trivial] Update license year range to 2019 (Emil Engler)
Pull request description:
Bitcoin Core is going to become 10 so the license year range also needs an update.
2019 is coming very soon so it is the time to update the year range like every year.
Same as #12063

Pull request description:
`thread_local` seems to be highly controversial according to the discussion in #14953, so remove it again from the tests.
Also remove boost::thread_group in the test that uses it, since I am touching it anyway.

73b46eeb7ea78cab051d770e3fe8a0c0fbb43ef9 depends: qt 5.9.7 (fanquake)
095e765975c2204f7e730bc8f0716227e480caa5 depends: expat 2.2.6 (fanquake)
Pull request description:
This PR upgrades `expat` and `qt` in depends. The intention is to upgrade Qt in master to the latest point release of the current Qt LTS. This change can then be back-ported to the 0.17 branch (wether it makes it into 0.17.1 or not).
Then, sometime before the 0.18.0 release, we could move to using Qt 5.12+ in depends (which is also LTS). That discussion, as well as minimum supported Qt versions is in #13478.
### Qt 5.9.7
[Release announcement](https://blog.qt.io/blog/2018/10/23/qt-5-9-7-released/)
[Changelog](https://bugreports.qt.io/browse/QTBUG-70888?filter=20149)
### Expat 2.2.6
* Avoid doing arithmetic with NULL pointers in XML_GetBuffer
* Fix 2.2.5 regression with suspend-resume while parsing a document like <root/>
Full changelog [here](https://github.com/libexpat/libexpat/blob/R_2_2_6/expat/Changes)
a46c8476e9 disables a bunch of qt features we aren't currently using. This speeds up the qt depends build slightly (also decreases the size of the built `qt-5.9.7` tar by about 2%). The disabling is somewhat unintuitive, hence `[wip]` until after a travis run and gitian build.

dcb70b152292a8df9fe834bacdf231ea848819b1 Indicate -rpcauth option password hashing alg (Carl Dong)
Pull request description:
By indicating the password hashing algorithm, users of bitcoin distributions without the script in `share/rpcauth` and users who don't want to rely on said script can use alternative means to generate the password hash.
Question for reviewers: perhaps we should also indicate that it is specifically a HMAC-SHA-256 of the _**UTF-8**_ encoding of their password?
