refactor: Rename system_{memory,...} to os_{memory,...}.
This rename happens in the system PR, so I'm pulling it out to reduce

cleanup: Use memzero(x, s) instead of memset(x, 0, s).
It's clearer and doesn't risk having a non-zero filler value.

cleanup: Remove plan9 support.
We really don't support it. I tried for half an hour to get some kind of
plan9 cross compilation to work, but it's not working. If anyone wants
to bring it back, they are welcome to send a PR including a CI check for
it. Until then, these 5 lines of unused code are gone.

endifs to be consistent.

refactor: Add common msgpack array packer with callback.
There will be more object arrays that need to be packed. This function
takes care of NULL (creating an empty array), and putting the correct
array size and calling the per-element callback the right amount of
times.

refactor: Allow NULL pointers for byte arrays in events.
Some events, notably the file chunk recv one, can give NULL pointers to
the client. Not sure they should, but that's what happens, so we support
it.

cleanup: make some improvements to group moderation test
- We no longer assert peer roles in the mod event callback
because this causes an issue with the new events implementation,
which triggers the events after all the packets from the
current tox_iterate() are processed, rather than as the
packets are received. These checks were superfluous and shouldn't
reduce code coverage.
- A moderator now sets the topic before the founder kicks him in
order to increase internal code coverage.

cleanup: Remove bin_pack_{new,free}.
We should only ever use `bin_pack_obj` and friends, which stack-allocate
the packer and pass it to callbacks.

feat: Add dht_get_nodes_response event to the events system.
Should probably rename it to something starting with `debug_` and make
it opt-in. Right now, it absolutely spams the events object.

cleanup: Remove old type-ordered event getters.
These are quite expensive, because they go through all events to index
in a typed array that no longer exists. Clients should index in the
union array and find the event they want themselves, or use dispatch.

fix: Make all the fuzzers work again, and add a test for protodump.
fuzz_select_target wasn't selecting anything, so fuzzers using that
function either did nothing or would only ever select one of the
functions.

Only applied in one place, but perhaps later we can implement a pattern
in tokstyle to find more opportunities for using memdup.

fix: Remove fatal error for non-erroneous case
We allow non-null data pointers to be passed to functions
alongside 0-length data. For example when creating a data
buffer that has room for the entire packet, including ignored
header data.

This error broke a rare but legitimate case where we miss
packets during a handshake attempt and need to store empty
handshake packets in the packet array.

fix: issues with packet broadcast error reporting
commit 5b9c420c introduced some undesirable behaviour with packet send
functions returning error when they shouldn't. We now only return an
error if the packet fails to be added to the send queue or cannot
be wrapped/encrypted. We no longer error if we fail to send the packet
over the wire, because toxcore will keep trying to re-send the packet
until the connection times out.

Additionally, we now make sure that our packet broadcast functions
aren't returning an error when failing to send packets to peers
that we have not successfully handshaked with yet, since this is
expected behaviour.

cleanup: Make group packet entry creation less error-prone
We always assumed that create_array_entry() would only be called
with an empty array entry and wouldn't modify entries on error.
We now explicitly require both conditions, and also give an
error in the case of a non-null data pointer with a zero
length field, as this indicates a logic error.

Checks for an empty array entry that precede a call to
create_array_entry() are now redundant. It should be noted that
a non-empty entry doesn't necessarily indicate an error. This
condition can be triggered if packets are being sent or
received faster than they can be processed/acknowledged,
which is common when spamming messages on poor connections.

refactor: Minor refactoring of get_close_nodes functions.
Avoiding passing down the entire DHT struct pointer to the inner
functions makes it possible in the future to write unit tests without
having to construct a full DHT object.

fix: don't pass garbage data buffer to packet send functions
This garbage data was never looked at due to passing
a zero length along with it, but it's still undesirable.

None of the others use out parameters. Also no toxcore function uses out

chore: Add fetch-sha256 script to update bootstrap node hash.
This fetches it from github, so we don't need to build it locally.

Not super ideal, because devs are supposed to build it locally to prove
reproducibility, but we can keep that diligence on the dev to do once
when actually merging the PR.

Add groupchat API function that returns an IP address string for a peer
This function will return an IP address string associated with a peer.
If the peer is not accepting direct connections a placeholder value
will be returned, indicating that their real IP address is unknown.
We do not return TCP relay IP addresses because a TCP connection
with a peer may use multiple relays simultaneously.

This mainly saves spam in test logs, but may save some packets here and
