9df32e820d scripted-diff: test: replace command with msgtype (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR to https://github.com/bitcoin/bitcoin/pull/18533, which changed the naming of `strCommand` to `msg_type` in the network processing code. The same approach is done here for the function test framework, to get rid of the wrong "command" terminology for network mesage types. (Commands are usually used in the CLI or RPC context, so using the same name in the network message context would only be confusing.)
The commit was created through the following steps:
1. search for all occurences of the string "command" within the folder `test/functional`
```git grep -i command test/functional > command_finds```
2. manually sort out all false-positives, i.e. occurences of "command" which describe commands in the correct sense (mostly CLI or RPC related, also some with Socks5)
3. put the remaining occurences into a scripted-diff (a quite simple one, actually) that renames "command" to "msgtype" in the concerned files.
The name `msgtype` was intentionally chosen without the underscore `_` as classes beginning with `msg_` define concrete types of messages.

ACK 9df32e820d . Makes sense that tests use the same naming as Bitcoin Core. See `NetMsgType` here: https://doxygen.bitcoincore.org/namespace_net_msg_type.html

This is the functional test framework pendant for
7777e3624f, which renamed "strCommand" with
"msg_type" in the network processing code.

The interfaces for the methods wait_for_header() and wait_for_merkleblock() are
changed to take a hex string instead of an integer, improving type safety and
removing the burden from the caller to always do the transformation via
`int(...)`. As suggested by MarcoFalke in
https://github.com/bitcoin/bitcoin/pull/18593#discussion_r407062253
Implements the missing initialization/serialization methods for
msg_merkleblock, based on the already present class CMerkleBlock.
Also changes the method wait_for_merkleblock() to be more precise by waiting
for a merkleblock with a specified blockhash instead of an arbitrary one.
In the BIP37 test p2p_filter.py, this new method is used to make the test of
receiving merkleblock and tx if a filter is set to be more precise, by checking
if they also arrive in the right order.
The asyncio.new_event_loop() instance is now removed from the NetworkThread
class during shutdown. This enables a NetworkThread instance to be restarted
after being closed. The current NetworkThread class guards against an existing
new_event_loop during initialization.
9f9db39041 QA/mininode: Send all headers upfront in send_blocks_and_test to avoid sending an unconnected one (Luke Dashjr)
Pull request description:
While this doesn't currently trigger any problems, the network protocol does expect headers to be sent connectable in normal circumstances, and if too many are sent out of order will disconnect the peer.

Pull request description:
- Adds `p2p_invalid_messages.py`: tests based on behavior for dealing with invalid and malformed P2P messages. Includes a test verifying that we can't DoS a node by spamming it with large invalid messages.
- Adds `TestNode.assert_memory_usage_stable`: a context manager that allows us to ensure memory usage doesn't significantly increase on a node during some test.
- Adds `P2PConnection.send_raw_message`: which allows us to construct and send messages with tweaked headers.

If a node has not announced a tx at all, then it should respond to
getdata messages for that tx with notfound, to avoid leaking tx
origination privacy.

https://github.com/bitcoin/bitcoin/pull/13715 introduced a new check
for _transport.is_closing() in mininode's P2PConnection's. This function
is only available from Python 3.4.4, though, while Bitcoin is supposed
to support all Python 3.4 versions.
In this change, we make the check conditional on is_closing() being
available. If it is not, then we revert to the behaviour before the
check was introduced; this means that
https://github.com/bitcoin/bitcoin/issues/13579 is not fixed for old
systems, but at least the tests work as they used to do before.
This includes a small refactoring from a one-line lambda to an
inline function, because this makes the code easier to read with more
and more conditions being added.
Fixes https://github.com/bitcoin/bitcoin/issues/13745.
The new P2PDataStore class was sending full blocks in headers messages,
which meant that calls to send_blocks_and_test() would blow up memory if
called with a large number of blocks. Fix that by only sending headers
in headers messages.

Next step in #10603
- first commit changes log level for an internal log from INFO to DEBUG. (Not really related, but I started finding the INFO level logging annoying when debuging test failures)
- second commit introduces a `P2PStub` class - a subclass of `NodeConnCB` which has its own block and tx store and responds appropriately to getdata requests. Not all the functionality is used in `invalidtxrequest.py`, but will be used in `invalidblockrequest.py` and `p2p-fullblocktest` when those are changed to use `BitcoinTestFramework`
- third commit tidies up `invalidtxrequest.py`
- fourth commit removes usage of `ComparisonTestFramework`

Add network thread_start(), network_thread_running() and
network_thread_join() utility functions in mininode.py and use
network_thread_running() in network thread assertions.
