522b80b33f add `--retry 5` to curl opts in install_db4.sh (qubenix)
Pull request description:
I ran into some network issue that caused the clang patch to not download and the script exited. A retry would have solved it. The fallback choice, `wget`, has a default 20 retries.
I chose 5 retries because `curl` backs of after each try, starting at one second and doubling each time. 5 retries means that worst case scenario would be a total of 31 seconds waiting between attempts. IMO that should be enough tries if internet is working, but not too much if internet is not working.

Calling getblocktemplate without the segwit rule specified is most
likely a client error, since it results in lower fees for the miner.
Prevent this client error by failing getblocktemplate if called without
the segwit rule specified.

45842c3d2 Improve documentation for running verify-commits.py script (Jameson Lopp)
Pull request description:
I ran into 3 different issues while trying to run the verify-commits script for the first time and I think documenting them would help save time for future developers.
1. I was trying to just run it with "python" and didn't realize I had multiple python versions installed and this script is only syntactically valid for python 3.x.
2. I needed to import the trusted keys
3. The script was hanging because it was triggering my yubikey for signature verification

Building with gcc 8.2 against musl libc, which apparently has more attributes
available in its sched_param. The following warnings were produced:
warning: missing initializer for member 'sched_param::sched_ss_low_priority' [-Wmissing-field-initializers]

Since the current thread may have interesting non-zero values for these fields,
we want to be sure to only change the intended one. Query and modify the

02e1e4eff6 rpc: Add wait argument to stop (João Barbosa)
Pull request description:
Fixes#11777. Reverts #11006. Replaces #13501.
With this change the HTTP server will exit gracefully, meaning that all requests will finish processing and sending the response, even if this means to wait more than 2 seconds (current time allowed to exit the event loop).
Another small change is that connections are accepted even when the server is stopping, but HTTP requests are rejected. This can be improved later, especially if chunked replies are implemented.
Briefly, before this PR, this is the order or events when a request arrives (RPC `stop`):
1. `bufferevent_disable(..., EV_READ)`
2. `StartShutdown()`
3. `evhttp_del_accept_socket(...)`
4. `ThreadHTTP` terminates (event loop exits) because there are no active or pending events thanks to 1. and 3.
5. client doesn't get the response thanks to 4.
This can be verified by applying
```diff
// Event loop will exit after current HTTP requests have been handled, so
// this reply will get back to the client.
StartShutdown();
+ MilliSleep(2000);
return "Bitcoin server stopping";
}
```
and checking the log output:
```
Received a POST request for / from 127.0.0.1:62443

```
For this reason point 3. is moved right after all HTTP workers quit. In that moment HTTP replies are queued in the event loop which keeps spinning util all connections are closed. In order to trigger the server side close with keep alive connections (implicit in HTTP/1.1) the header `Connection: close` is sent if shutdown was requested. This can be tested by
```
bitcoind -regtest
nc localhost 18443
POST / HTTP/1.1
Authorization: Basic ...
Content-Type: application/json
Content-Length: 44
{"jsonrpc": "2.0","method":"stop","id":123}
```
Summing up, this PR:
- removes explicit event loop exit — event loop exits once there are no active or pending events
- changes the moment the listening sockets are removed — explained above
- sends header `Connection: close` on active requests when shutdown was requested which is relevant when it's a persistent connection (default in HTTP 1.1) — libevent is aware of this header and closes the connection gracefully
- removes event loop explicit break after 2 seconds timeout

a67d71311d [doc] developer-notes.md: point out that UniValue deviates from upstream (Sjors Provoost)
Pull request description:
While debugging an issue I was somewhat surprised to [learn](https://github.com/bitcoin/bitcoin/pull/14164#issuecomment-419752678) that we've moved `src/univalue` from https://github.com/jgarzik/univalue to https://github.com/bitcoin-core/univalue, that these repos are both maintained and they're different.
The first mention of using the bitcoin-core repo is from late 2015 in #7157. I didn't check when the last common ancestor commit is.
I couldn't find documentation as to why (these things just happen in open source of course), but at minimum we should make this more clear.
There's also the following line in `config.ac` that I'm not sure what to do with:
```
AC_INIT([univalue], [1.0.3],
[http://github.com/jgarzik/univalue/])

Pull request description:
scripted-diffs should be run in subshells so that their execution does not
affect the shell variables of commit-script-check. Shell variables are not
unset before evaluating the scripted-diff, so that they might be used in
the subshell. To this end, the variable previously named i is now more
descriptively named commit, this also allows scripted-diffs to use the
commonly used variable i without fear of losing a reference to the
commit.
