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.

This eases the during-type validation to allow Bech32 chars.

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.

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.

90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)
Pull request description:
Since C++11 the macro `NULL` may be:
* an integer literal with value zero, or
* a prvalue of type `std::nullptr_t`
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf
With this patch applied there are no `NULL` macro usages left in the repo:
```
$ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
0
```
The road towards `nullptr` (C++11) is split into two PRs:
* `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
* `0` → `nullptr` is handled in PR #10645 (manual)

9737572 [Qt] Use wallet 0 in rpc console if running with multiple wallets (Jonas Schnelli)
Pull request description:
Current master with multiwallet results in accessing wallet 0 in QT (send / receive / tx history / etc.), **but** the RPC console cannot access that wallet (only non-wallet commands work).
This is a quick solution to re-allow accessing the same wallet (Index 0) via RPC console in multiwallet.
The solutions design is not "state of the art" (should go over WalletModel). Ideally we work on an overall multiwallet support for the GUI (which then would remove this change).
I think we should consider this as a bugfix.

After this change: All the AppInit steps before and inclusive AppInitLockDataDirectory must not have Shutdown() called in case of failure. Only when AppInitMain fails, Shutdown should be called.
Changes the GUI and bitcoind code to consistently do this.

Alternative to #10818, alternative solution to #10815.
After this change: All the AppInit steps before and inclusive
AppInitLockDataDirectory must not have Shutdown() called in case of
failure. Only when AppInitMain fails, Shutdown should be called.

Remove helper function (CalculateEstimateType) for determining whether
estimates should be conservative or not, now that this is only called
once from GetMinimumFee and incorporate the logic directly there.
This fixes buggy behavior where we were temporarily setting and unsetting the
global payTxFee when trying to send a transaction with a custom fee from the
GUI. The previous behavior was inconsistent depending on the order of using the
RPC call settxfee and clicking various radio buttons in the sendcoinsdialog.
The new behavior is that transactions sent with the GUI will always use either
the smartfee slider value or the custom fee set on the GUI and they will not
affect the global defaults which are only for RPC and initial GUI values.

Add support for setting each of these attributes on a per RPC call basis to sendtoaddress, sendmany, fundrawtransaction (already had RBF), and bumpfee (already had RBF and conf target).
GetMinimumFee now passes the conservative argument into estimateSmartFee.
Call CalculateEstimateType(mode) before calling GetMinimumFee or estimateSmartFee to determine the value of this argument.
CCoinControl can now be used to control this mode.
