e90478f log: harmonize bitcoind server logging (Jon Atack)

Pull request description:

  Harmonize the user-facing output of the  `bitcoind -daemon`, `bitcoin-cli help stop`, `bitcoin-cli stop`, and `bitcoind -version` commands to be consistent with each other as well as with the "Bitcoin Core is probably already running" messages, e.g. `git grep 'probably already running.")'`.

  Before:

  ```
  $ bitcoind -regtest -daemon
  Bitcoin Core daemon starting

  $ bitcoind -regtest -daemon
  Error: Bitcoin Core is probably already running.

  $ bitcoind -regtest -version
  Bitcoin Core Daemon version v0.18.99.0-e653eeff76-dirty

  $ bitcoin-cli -regtest help stop
  stop

  Stop Bitcoin server.

  $ bitcoin-cli -regtest stop
  Bitcoin server stopping
  ```
  these five commands output:

  "Bitcoin Core daemon"
  "Bitcoin Core"
  "Bitcoin Core Daemon"
  "Bitcoin server"
  "Bitcoin server"

  After this commit, they are all "Bitcoin Core".

  ```
  $ bitcoind -regtest -daemon
  Bitcoin Core starting

  $ bitcoind -regtest -daemon
  Error: Bitcoin Core is probably already running.

  $ bitcoind -regtest -version
  Bitcoin Core version v0.18.99.0-e90478f43e-dirty

  $ bitcoin-cli -regtest help stop
  stop

  Request a graceful shutdown of Bitcoin Core.

  $ bitcoin-cli -regtest stop
  Bitcoin Core stopping
  ```

  I frequently run `make deploy` while testing on macOS to get a properly light themed .app. With a brew installed Qt, this currently results in a pretty bloated executable:

66740f4 doc: add a release note for the new field in 'getpeerinfo' and 'getnetworkinfo' (darosior)
6564f58 rpc/net: decode the services flags in a new entry (darosior)

Pull request description:

  This is a reopen of bitcoin#15511 (comment) since there have been concept ACKs from sdaftuar and Sjors.

  This adds a new entry to `getpeerinfo` and `getnetworkinfo` which decodes the network services flags.

  Here is a truncated output of `getpeerinfo`:
  ```
  "services": "000000000000040d",
  "servicesnames": "NODE_NETWORK | NODE_BLOOM | NODE_WITNESS | NODE_NETWORK_LIMITED",
  "relaytxes": true,
  ```
  And one of `getnetworkinfo`:
  ```
  "localservices": "0000000000000409",
  "localservicesnames": "NODE_NETWORK | NODE_WITNESS | NODE_NETWORK_LIMITED",
  "localrelay": true,
  ```

  Fixes bitcoin#16780.

ec4c793 signrawtransaction*: improve error for partial signing (Anthony Towns)
3c481f8 signrawtransactionwithkey: better error messages for bad redeemScript/witnessScript (Anthony Towns)

Pull request description:

  Two fixes for `signrawtransactionwith{key,wallet}` (in addition to bitcoin#16250): one that checks redeemScript/witnessScript matches scriptPubKey (and if both are provided that they match each other sanely), and the other changes the warning when some-but-not-all the signatures for a CHECKMULTISIG are provided to something that suggests more signatures may be all that's required.

1619684 Added libbitcoin_qt and bitcoin-qt to the msbuild configuration. (Aaron Clauson)

Pull request description:

  This PR has ~~90%~~ all of the work done to allow the bitcoin Qt programs to be built with msvc and the appveyor script.

  Outstanding issues:

  - ~~There are ~~3~~ ~~6~~ 5 code tweaks required for the bitcoin Qt components to be built without warnings with msvc. They seem minor~~,
  - Building Qt as a static library for Windows is painful and time consuming. I doubt it will ever be possible to build Qt from source as part of an appveyor job (and it would probably take over an hour even if it was). My tentative solution is to build locally and upload the binaries as a [github release](https://github.com/sipsorcery/qt_win_binary/releases). The msvc build is only for testing and tinkering but even so this doesn't feel like the ideal solution. Open to suggestions?
  - ~~There is still an issue to sort out with the payment request URL handling. Building Qt with openssl is an extra headache. I will continue to work on getting this working.~~

  The big benefit of this PR is the ability to run bitcoin-qt within a Visual Studio debugging session which could expedite tracking down issues on Windows.

  On a side note the test-bitcoin-qt tests fail very early, probably due to *nix specific tests. I haven't dug into them at this point.

  **Update 28 Jun 2019**: The ENABLE_BIP70 option is now off (it's flagged for removal as per bitcoin#15584). With it disabled msbuild does not require any code changes to build the Bitcoin Core Qt applications.

Recent questions have come up regarding dynamic service registration
(see bitcoin#16442 (comment)
and the assumeutxo project, which needs to dynamically flip NODE_NETWORK).

While investigating how dynamic service registration might work, I was
confused about how we convey local services to peers. This adds some
documentation that hopefully clarifies this process.

  To prevent OOM, Bitcoin Core will reject chain forks at low difficulty by default. This is the only use-case of checkpoints, so add a test for it to make sure the feature works as expected. If it didn't work, checkpoints would have no use-case and we might as well remove them

Pull request description:

  This adds a checkbox to the intro screen to enable pruning from the get go.

  If the user has plenty of space, it's unchecked by default:

  <img width="671" alt="big" src="https://user-images.githubusercontent.com/10217/63641289-10339000-c6ac-11e9-98d7-caf64dff0da6.png">

  If the user has insufficient space it's checked by default:
  <img width="897" alt="low" src="https://user-images.githubusercontent.com/10217/63641276-d4002f80-c6ab-11e9-9f5b-a53472f814ff.png">

  When the user has barely enough space and is likely to need pruning in the near future, this is shown in yellow and we also check the prune box:

  <img width="662" alt="medium" src="https://user-images.githubusercontent.com/10217/63641294-1c1f5200-c6ac-11e9-8ecb-6b69e42b1ece.png">

  The cut-off for this 10 GB above `m_assumed_blockchain_size` (`=240` in `chainparams.cpp`).

  If the user launches the first time with `-prune=...` then we disable the check box and display the correct size (rounded to GB):
  <img width="658" alt="Schermafbeelding 2019-08-24 om 20 23 14" src="https://user-images.githubusercontent.com/10217/63641351-09594d00-c6ad-11e9-94fe-fe5ed562e109.png">

  The 2 GB default matches the settings default. The user can't change it in the intro screen, but can change it later. I'm tempted to increase that default to 10 GB, and then have the intro screen reduce it if space is really tight.

  Tips for testing:
  * move your existing data dir elsewhere
  * wipe data dir at every restart (behavior is different if it exists)
  * launch with `bitcoin-qt -resetguisettings -lang=en` (there's some space issues in different languages)
  * fake your free space by changing `intro.cpp` line 90: `freeBytesAvailable = 5000000000; // 5 GB`
  * try both testnet and mainnet, because settings are seperate. In particular note how step 7 in `GuiMain` switches where `QTSettings settings` points to; this had me thoroughly confused on testnet, because I was setting them too early.

376f492 build: disable BIP70 support by default (fanquake)

Pull request description:

  Disable BIP70 support in the GUI by default for `0.19.0` (for eventual removal in `0.20.0`?).

  Users who want to compile with BIP70 support enabled can pass `--enable-bip70` to `./configure`.

  I've inverted the current `--disable-bip70` test to instead pass `--enable-bip70`.

  Tested configurations on `macOS` (`protobuf` installed with `brew`).
  Protobuf available and `./configure`:
  ```
  Options used to compile and link:
    with wallet   = yes
    with gui / qt = yes
      with bip70  = no
  ```

  Protobuf available and `./configure --enable-bip70`:
  ```
  Options used to compile and link:
    with wallet   = yes
    with gui / qt = yes
      with bip70  = yes
  ```

  Protobuf not available (i.e `brew unlink protobuf`) and `./configure`:
  ```
  Options used to compile and link:
    with wallet   = yes
    with gui / qt = yes
      with bip70  = no
  ```

  Protobuf not available and `./configure --enable-bip70`:
  ```
  checking whether to build test_bitcoin-qt... yes
  checking whether to build BIP70 support... configure: error: protobuf missing

3f89e1e Prevent processing duplicate payment requests (João Barbosa)

Pull request description:

  Considering the following from Qt [src/plugins/platforms/cocoa/qcocoaapplicationdelegate.mm#L267](https://github.com/qt/qtbase/blob/13e0a36626bd75e631dd9536e795a494432b1945/src/plugins/platforms/cocoa/qcocoaapplicationdelegate.mm#L267)

  ```cpp
  - (void)application:(NSApplication *)sender openFiles:(NSArray *)filenames
  {
      Q_UNUSED(filenames);
      Q_UNUSED(sender);

      for (NSString *fileName in filenames) {
          QString qtFileName = QString::fromNSString(fileName);
          if (inLaunch) {
              // We need to be careful because Cocoa will be nice enough to take
              // command line arguments and send them to us as events. Given the history
              // of Qt Applications, this will result in behavior people don't want, as
              // they might be doing the opening themselves with the command line parsing.
              if (qApp->arguments().contains(qtFileName))
                  continue;
          }
          QWindowSystemInterface::handleFileOpenEvent(qtFileName);
      }
  ```

  And that a2714a5 was merged, now Qt isn't able to filter out the above notifications, and then a [QFileOpenEvent](https://doc.qt.io/qt-5/qfileopenevent.html) event is delivered to `PaymentServer::eventFilter`, which in turn (re)adds the payment request.

  This change fixes bitcoin#17025, but makes sense regardless of the issue.

This commit does not change behavior as GetBlocksDir() with unset 
"-blocksdir" returns the same path.
Since libtool 1.5.2, on Linux libtool no longer sets RPATH for any
directories in the dynamic linker search path, so there is no longer an
issue.
This commit reverts a98356f.
`bitcoinstrings.cpp` is to be generated at release time. Hence,
it should not depend on whether the source files are younger as the
releaser may proceed from a fresh checkout.

…of magic bytes rather than fail

3284e6c scripts: search for next position of magic bytes rather than fail (Tim Akinbo)

Pull request description:

  When using the `linearize-data.py` contrib script to export block data, there are edge cases where the script fails with an `Invalid magic: 00000000` error. This error occurs due to the presence of padding bytes that occasionally appears between consecutive blocks in the block data file.

  There's an ongoing conversation about this in bitcoin#14986. sipa also admitted that it is a bug in bitcoin#5028. Fortunately, this is not an issue in bitcoin core as it handles this type of situation gracefully and so no fix in bitcoin core is required.

  This PR is an improvement on how the script handles these "invalid magic bytes". Rather than failing, this patch allows the script to search for the next occurrence of the magic bytes and then starts reading the block from there.

7fb7acf Set init stop timeout to 10 min (setpill)

Pull request description:

  `bitcoind` can take a long time to flush its db cache to disk upon
  shutdown. Systemd sends a `SIGKILL` after a timeout, causing unclean
  shutdowns and triggering a long "Rolling forward" at the next startup.
  Disabling the timeout should prevent this from happening, and does not
  break systemd's `restart` logic.

  Addresses bitcoin#13736.

Pull request description:

  Adds a `sortedmulti()` descriptor as mentioned in bitcoin#17023 (comment).

  `sortedmulti()` works in the same way as `multi` does but sorts the pubkeys in the resulting scripts in lexicographic order as described in [BIP67](https://github.com/bitcoin/bips/blob/master/bip-0067.mediawiki). Note that this does not add support for BIP67 nor is BIP67 fully supported by this descriptor (which is why it is not named `multi67()`) as it does not require compressed pubkeys.

  Tests from BIP67 were added and documentation was updated.
