fa6ab8ada1 rpc: Return more specific reject reason for submitblock (MarcoFalke)
Pull request description:
The second commit in #13439 made the `TODO` in the first commit impossible to solve.
The meaning of `fNewBlock` changed from "This is the first time we process this block" to "We are about to write the new *valid* block".
So whenever `fNewBlock` is true, the block was valid. And whenever the `fNewBlock` is false, the block is either valid or invalid. If it was valid and not new, we know it is a `"duplicate"`. In all other cases, the `BIP22ValidationResult()` will return the reason why it is invalid.

8f5d9431a Add regtests for HTTP status codes. (Daniel Kraft)
Pull request description:
This adds explicit tests for the returned HTTP status codes to `interface_rpc.py` (for error cases) and the HTTP JSON-RPC client in general for success.
#15381 brought up discussion about the HTTP status codes in general, and the general opinion was that the current choice may not be ideal but should not be changed to preserve compatibility with existing JSON-RPC clients. Thus it makes sense to actually test the current status to ensure this desired compatibility is not broken accidentally.

8b8d8eeae9 Remove travis_wait from lint script (Graham Krizek)
Pull request description:
Using the `travis_wait` command in conjunction with `set -o errexit` causes problems. The `travis_wait` command will correctly log the command's output if successful, but if the command fails the process exits before the `travis_wait` command can dump the logs. This will hide important debugging information like error messages and stack traces. We ran into this in #15196 and it was very hard to debug because output was being suppressed.
`travis_wait` was being used because the `contrib/verify-commits/verify-commits.py` script can sometimes run for a long time without producing any output. If a script runs for 10 minutes without logging anything, the CI run times out. The `travis_wait` command will extend this timeout by logging a message for you, while sending stderr and stdout to a file.
This PR removes the `travis_wait` command from our CI system and adds additional logging to the `verify-commits.py` script so it doesn't make Travis timeout.

Steps to reproduce the issue:

mkdir /tmp/foo && chmod a-r /tmp/foo
# 2. run bitcoin-qt and should print an error, but continues running:
/Volumes/Bitcoin-Core/Bitcoin-Qt.app/Contents/MacOS/Bitcoin-Qt -regtest -walletdir=/tmp/foo
/private/tmp/foo: Permission denied
# 4. go to File -> Open Wallet and should segfault:

Pull request description:
Upgrade the ZeroMQ dependency from version 4.2.3 to the latest stable version 4.2.5.
This PR Follows the lead of https://github.com/bitcoin/bitcoin/pull/11986.
I upgraded both patch files to correspond to the version `4.2.5` libzmq files.
I assume doing so is still necessary and correct.
Without updating the patch line numbers, things appear to work, but you get extra log messages while building `depends` because things don't exactly match, e.g.:
```
/bitcoin/depends> make zeromq
Extracting zeromq...
/bitcoin/depends/sources/zeromq-4.2.5.tar.gz: OK
Preprocessing zeromq...

patching file src/thread.cpp
Hunk #1 succeeded at 307 with fuzz 2 (offset 87 lines).
Hunk #2 succeeded at 323 with fuzz 2 (offset 90 lines).
```
Updating the patches seemed cleaner, so I did it. Note that libzmq had some whitespace changes, so that's why the updated patches do too.

f7453dcc0386a4a1162ced1a490c096afa13178a build: remove linking librt for backwards compatibility (fanquake)
Pull request description:
Now that we require glibc 2.17+, see #17538, we can remove linking librt
for backwards compatibility purposes. The `clock_*` functions from librt
were merged into glibc as part of the [2.17 release](https://sourceware.org/ml/libc-announce/2012/msg00001.html):
* The `clock_*` suite of functions (declared in <time.h>) is now available
directly in the main C library. Previously it was necessary to link with
-lrt to use these functions. This change has the effect that a
single-threaded program that uses a function such as `clock_gettime' (and
is not linked with -lrt) will no longer implicitly load the pthreads
library at runtime and so will not suffer the overheads associated with
multi-thread support in other code such as the C++ runtime library.
Note that `librt` is already unused by the RISC-V and AARCH64 binaries as their librts don't export any `clock_*` functions. As an example, you can find a diff of the arm32 vs arm64 librt symbols [here](https://gist.github.com/fanquake/b08cb1f0d14df3133395d7796ebf030c).

Pull request description:
Digging into #15240 the lack of the proper logging has been discovered.
Fixed by this PR.
UPDATE (inspired by @laanwj's [comment](https://github.com/bitcoin/bitcoin/pull/15278#discussion_r252641810)):
Not being able to create the PID file is fatal now.

**Notes for reviewers**
1. `CreatePidFile()` has been moved from `util/system.cpp` to `init.cpp` for the following reasons:
- to get the ability to use `InitError()`
- now `init.cpp` contains code of both creating PID file and removing it
2. Regarding 0.18 release process: this PR modifies 1 string and introduces 2 new ones.
