The LevelDB docs seem to indicate that an iterator will not take
snapshots (even providing instructions on how to do so yourself).
In several of the places we use them, we assume snapshots to have
been taken.
In order to make sure LevelDB doesn't change out from under us
(and to prevent the next person who reads the docs from having the
same fright I did), verify that snapshots are taken in our tests.
f97ab35fa qa: Fix bug introduced in p2p-segwit.py (Suhas Daftuar)
a7820422e qa: Treat mininode p2p exceptions as fatal (Suhas Daftuar)
Pull request description:
#11121 inadvertently broke the constructor for the `TestNode()` object in `p2p-segwit.py`, silently breaking at least one of the tests.
Although the python code was raising exceptions due to a `TestNode()` object not existing (or having the right type), mininode was masking these from anyone running the test through the test_runner (like travis), because it catches all exceptions during message delivery and just prints a log message and continues. Such "graceful" handling of errors is almost certainly something we don't want in our test suite, so the first commit here attempts to prevent that type of failure from ever being masked.
The second commit fixes the particular bug in `p2p-segwit.py`.

fd849e1b0 Change AcceptToMemoryPool function signature (Alex Morcos)
Pull request description:
First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.
Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)
Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

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.

Pull request description:
This is a greatly simplified version of #10285, which only aims to address async resolving.
It essentially breaks up two wrapper functions for things only used in one place (ConnectSocketDirectly/ConnectThroughProxy) in favor of calling them directly. This allows us to fully handle resolves before attempting a connection, as is necessary for async connections.
As a bonus, I believe the logic is now much easier to follow than before.

Pull request description:
The `getblockchaininfo` output does not contain the `errors` field which the `getinfo`, `getmininginfo`, and `getnetworkinfo` RPCs have. It should have it as the errors pertain to the blockchain. This PR adds that field.
This PR also unifies the help text for the `errors` field and its output position so that all of the `get*info` commands are consistent.
`getnetworkinfo`'s `errors` field is named `warnings`. I did not change this even though it is inconsistent since this naming has been in use for a long time.

fa082b4 doc: move gitian building to external repo (MarcoFalke)
Pull request description:
The guide was moved to [the Bitcoin Core documentation repository](https://github.com/bitcoin-core/docs/blob/master/gitian-building.md).
It now includes not only instructions to run on a debian host, but also on
any recent fedora host.
This is an ongoing effort to reduce the fraction caused by incoming
pull requests to docs (usually fixups, typo fixes, version bumps).
This is especially important for documentation that is independent
of any release cycles and should thus be up-to-date regardless
of a tag on a non-master branch.
Finally, fetching a shallow copy of the source is less heavy,
as many binary png files are moved out of the repo.

This adds the infrastructure `BaseRequestHandler` class that takes care
of converting bitcoin-cli arguments into a JSON-RPC request object, and
converting the reply into a JSON object that can be shown as result.
This is subsequently used to handle the `-getinfo` option, which sends
a JSON-RPC batch request to the RPC server with
`["getnetworkinfo", "getblockchaininfo", "getwalletinfo"]`,
and after reply combines the result into what looks like a `getinfo`
result.
There have been some requests for a client-side `getinfo` and this
is my PoC of how to do it. If this is considered a good idea
some of the logic could be moved up to rpcclient.cpp and
used in the GUI console as well.

d4cdbd6fb [rpc] Deprecate estimatefee RPC (John Newbery)
Pull request description:
Deprecates estimatefee in v0.16, for final removal in v0.17.
This commit introduces a phased removal of RPC methods. RPC method is
disabled by default in version x, but can be enabled by using the
`-deprecatedrpc=<methodname>` argument. RPC method is removed entirely in version
(x+1).
This gives users fair warning that an RPC is to be removed, and time to change client software if necessary. Deprecation warnings in RPC return values or release notes are easily ignored.
This is a more generic version of the approach I tried to use in #10841, which too late to make it into v0.15.

df10edf More user-friendly error message when partially signing (MeshCollider)
Pull request description:
When partially signing a transaction using `signrawtransaction`, if the wallet doesn't have access to a key, it will output a scary error message `"error": "Operation not valid with the current stack size"`, yet it will partially sign the transaction anyway. This puts a lot of users off, because they don't realise the signing actually succeeded for some inputs. This catches that specific error when signing, and outputs a friendlier message which says `Unable to sign input, invalid stack size (possibly missing key)`.
This is the best way I could think of to fix the issue, but please let me know if you come up with a better way to do it :)

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.
