faee59103d test: Fix race in mempool_accept (MarcoFalke)
Pull request description:
If we happen to pick the same random coin to spend, there would be mempool conflicts in some runs of the test. Fix that by popping from a static list of coins to spend from.

Also add .python-version for pyenv which will cause tests with too
modern syntax to fail on developer machine rather than on Travis.

Pull request description:
https://github.com/bitcoin/bitcoin/pull/14565 needs test coverage. This PR refactors wallet_importmulti.py to the following pattern:
1. Add `get_key()` and `get_multisig()` methods, which generate keys on node0 and return the priv/pubkeys and all scriptPubKey and address variants.
2. Add `test_importmulti()` method, which takes an importmulti request, sends it to node1 and tests against success and error codes/messages.
3. Add `test_address()` method, which takes an address, sends it as a getaddressinfo request to node1 and tests the values returned.
This does not add any specific testing for #14565, but makes it very straightforward to add that testing: `test_importmulti()` can be easily updated to test for returned warnings, and `test_address()` can be called multiple times against the different address variants for a singlesig/multisig.

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

43f9099901 scripted-diff: Run scripted-diff in subshell (Carl Dong)
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.

48b37db50 make peertimeout a debug argument, remove error message translation (Zain Iqbal Allarakhia)
8042bbfbf p2p: allow p2ptimeout to be configurable, speed up slow test (Zain Iqbal Allarakhia)
Pull request description:
**Summary:**
1. _Primary_: Adds a `debug_only=true` flag for peertimeout, defaults to 60 sec., the current hard-coded setting.
2. _Secondary_: Drastically speeds up `p2p_timeout.py` test.
3. _Secondary_: Tests that the correct code path is being tested by adding log assertions to the test.
**Rationale:**
- P2P timeout was hard-coded: make it explicitly specified and configurable, instead of a magic number.
- Addresses #13518; `p2p_timeout.py` takes 4 sec. to run instead of 61 sec.
- Makes `p2p_timeout.py` more explicit. Previously, we relied on a comment to inform us of the timeout amount being tested. Now it is specified directly in the test via passing in the new arg; `-peertimeout=3`.
- Opens us up to testing more P2P scenarios; oftentimes slow tests are the reason we don't test.

b06483c96a Remove stale comment in CalculateMaximumSignedInputSize (Gregory Sanders)
Pull request description:
This is triggered anytime a fundraw type call(psbt or legacy) is used with a change output address that the wallet doesn't know how to sign for.
This regression was added in 6a34ff5335 since BnB coin selection actually cares about this.
The fix is to assume the smallest typical spend, a P2SH-P2WPKH, which is calculated using a "prototype" dummy signature flow. Future work could generalize this infrastructure to get estimated sizes of inputs for a variety of types.
I also removed a comment which I believe is stale and misleading.
