Terminal: change command-line parser (#2247) Change the underlying command line handling: - switch to a custom parser, inspired by redis / sds - update terminalRegisterCommand signature, pass only bare minimum - clean-up `help` & `commands`. update settings `set`, `get` and `del` - allow our custom test suite to run command-line tests - clean-up Stream IO to allow us to print large things into debug stream (for example, `eeprom.dump`) - send parsing errors to the debug log As a proof of concept, introduce `TERMINAL_MQTT_SUPPORT` and `TERMINAL_WEB_API_SUPPORT` - MQTT subscribes to the `<root>/cmd/set` and sends response to the `<root>/cmd`. We can't output too much, as we don't have any large-send API. - Web API listens to the `/api/cmd?apikey=...&line=...` (or PUT, params inside the body). This one is intended as a possible replacement of the `API_SUPPORT`. Internals introduce a 'task' around the AsyncWebServerRequest object that will simulate what WiFiClient does and push data into it continuously, switching between CONT and SYS. Both are experimental. We only accept a single command and not every command is updated to use Print `ctx.output` object. We are also somewhat limited by the Print / Stream overall, perhaps I am overestimating the usefulness of Arduino compatibility to such an extent :) Web API handler can also sometimes show only part of the result, whenever the command tries to yield() by itself waiting for something. Perhaps we would need to create a custom request handler for that specific use-case.
