There were 2 bugs: * `gateway_awaiting_connections` should represent gateways were there is an on-going connection intent but are not connected yet but currently we were creating an empty entry when there was no entry, even if there is a connection established, this would cause the next resource connection intent to stop early without adding the allowed ip, thus never using the connection. * There was a race condition, where if the `ReuseConnection` was sent to the gateway when the connection wasn't established, the gateway would just ignore the message, but this connection intent would never be sent again. Now that I'm writing this maybe the best solution is, if there is a pending connection to a gateway, we just do nothing. That way upper layers would just retry the message and we send `ReuseConnection` once the connection is established instead of buffering the requests... Edit: that's exactly the fix I made.

Building Connlib
Setting the CONNLIB_MOCK environment variable when packaging for Apple or Android will activate the mock feature flag, replacing connlib's normal connection logic with a mock for testing purposes.
- You'll need a Rust toolchain installed if you don't have one already. We recommend following the instructions at https://rustup.rs.
rustup showwill install all needed targets since they are added torust-toolchain.toml.- Follow the relevant instructions for your platform:
- Apple
- Android
- Linux
- Windows
Apple
Connlib should build successfully with recent macOS and Xcode versions assuming you have Rust installed. If not, open a PR with the notes you found.
