Pull request description:

  This is a bugfix, since wallet_dump currently uses the wrong name:

  18857b4c40/test/functional/wallet_dump.py (L89-L92)

  Rename all to the same name with a scripted diff (and some unrelated cleanups).

Pull request description:

  This is an alternative to #14558 (it will warn when fields are being ignored). In addition:
  * It makes sure no changes to the wallet are made when an error in the input exists.
  * It validates all arguments, and will fail if anything fails to parse.
  * Adds a whole bunch of sanity checks

Merge #14653: rpcwallet: Add missing transaction categories to rpc helptexts
f3f6dde56e Test coinbase category in wallet rpcs (andrewtoth)
e982f0b682 Add all category options to wallet rpc help (andrewtoth)

Pull request description:

  The current helptext for `listtransactions`, `listsinceblock` and `gettransaction` only list two of the five possible options for `category`. This incorrectly implies that these are the only two options, and can cause problems if the other three options aren't accounted for. Also, some of the documentation is incorrect when specifying which options are returned for which categories.

  This PR updates the helptext for these RPCs and adds a functional regression test for the cases when the other three categories are returned.

bdacbda253 Overhaul importmulti logic
This introduces various changes to the importmulti logic:
* Instead of processing input and importing things at the same time, first
  process all input data and verify it, so no changes are made in case of
  an error.
* Verify that no superfluous information is provided (no keys or scripts
  that don't contribute to solvability in particular).
* Add way more sanity checks, by means of descending into all involved
  scripts.

cb41ade6b1 [tests] fix flake8 warnings in wallet_importmulti.py (John Newbery)

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
      ThreadRPCServer method=stop user=__cookie__

      ... sleep 2 seconds ...

      Waiting for HTTP event thread to exit
      Stopped HTTP server
  ```

  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

Merge #14733: P2P: Make peer timeout configurable, speed up very slow test and ensure correct code path tested.
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.
