Merge #11499: [Qt] Add upload and download info to the peerlist (debug menu)
6b1891e2c Add Sent and Received information to the debug menu peer list (Aaron Golliver)
8e4aa35ff move human-readable byte formatting to guiutil (Aaron Golliver)

Pull request description:

  Makes the peer list display how much you've uploaded/downloaded from each peer.

  Here's a screenshot ~~[outdated](https://i.imgur.com/MhPbItp.png)~~, [current](https://i.imgur.com/K1htrVv.png) of how it looks. You can now sort to see who are the peers you've uploaded the most too.

  I also moved `RPCConsole::FormatBytes` to `guiutil::formatBytes` so I could use it in the peerlist

  * You can define the start and end-height
  * It can be called during runtime
  * It can work in multiwallet environment

Pull request description:

  Builds on top of #11117.

  This adds support for:
  * Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
  * Sending to BIP173 addresses (including non-v0 ones)
  * Analysing BIP173 addresses (through `validateaddress`)

  It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.

  Not included (and intended for other PRs):
  * Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
  * Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
  * Error locating in UI for BIP173 addresses.

Merge #11335: Replace save|restoreWindowGeometry with Qt functions
13baf72 Replace save|restoreWindowGeometry with Qt functions (MeshCollider)

Pull request description:

  Alternative to https://github.com/bitcoin/bitcoin/pull/11208, closes https://github.com/bitcoin/bitcoin/issues/11207

  According to the [Qt documentation](https://doc.qt.io/qt-4.8/qwidget.html#restoreGeometry), restoreGeometry does all the checks we need, so it would be better to rely on them instead of doing it ourselves.

  ~Haven't tested this properly yet, hence the WIP.~
  Gives expected behavior exactly as the other system apps do based on my tests. Only potential issue is the case when the GUI is almost entirely offscreen with only a single strip of pixels, its not really possible to see the GUI, but if you know it's there you can bring it back onscreen with just the mouse. And that's exactly how notepad behaves on Windows so I don't think its a real issue.

  This also gives much better behavior when closing a maximized window, currently (0.15.0 release) a maximized window will save the window size on close, and then reopen as a not-maximized but still that size, which is really annoying. This reopens as maximized.

  Gitian build here: https://bitcoin.jonasschnelli.ch/build/305

Merge #11117: Prepare for non-Base58 addresses
864cd2787 Move CBitcoinAddress to base58.cpp (Pieter Wuille)
5c8ff0d44 Introduce wrappers around CBitcoinAddress (Pieter Wuille)

Pull request description:

  This patch removes the need for the intermediary Base58 type `CBitcoinAddress`, by providing {`Encode`,`Decode`,`IsValid`}`Destination` functions that directly operate on the conversion between `std::string`s and `CTxDestination`.

  As a side, it also fixes a number of indentation issues, and removes probably several unnecessary implicit `CTxDestination`<->`CBitcoinAddress` conversions.

  This change is far from complete. In follow-ups I'd like to:
  * Split off the specific address and key encoding logic from base58.h, and move it to a address.h or so.
  * Replace `CTxDestination` with a non-`boost::variant` version (which can be more efficient as `boost::variant` allocates everything on the heap, and remove the need for `boost::get<...>` and `IsValidDestination` calls everywhere).
  * Do the same for `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey`.

  However, I've tried to keep this patch to be minimally invasive, but still enough to support non-Base58 addresses. Perhaps a smaller patch is possible to hack Bech32 support into `CBitcoinAddress`, but I would consider that a move in the wrong direction.

Merge #11234: Remove redundant testutil.cpp|h files
d1138e362 Remove redundant testutil files (MeshCollider)

Pull request description:

  The only function in testutil.cpp, `GetTempPath()` simply called `fs::temp_directory_path()` directly. This just tidies things up by removing that redundant function and the file containing it

  I can understand wanting a general util file for tests to use, but if there's nothing in it, we might as well remove it, it can always be added back later when it's put to use.

Merge #11179: rpc: Push down safe mode checks
ec6902d0e rpc: Push down safe mode checks (Andrew Chow)

Pull request description:

  This contains most of the changes of #10563 "remove safe mode" by @achow101, but doesn't remove the safe mode yet, but put an `ObserveSafeMode()` check in (all 23) individual calls which used to have okSafeMode=false.

  This cleans up the ugly "okSafeMode" flag from the dispatch tables, which is not a concern for the RPC server.
