Make use of `esp_idf_svc::eventloop::EspSystemEventLoop` instead of `loop`?

[juliankrieger]

I'm currently weighing my options between diving into esp32 internals and doing it myself or asking for your help.

What effort do you think it would take to move the ble_server loop into the aforementioned sysloop?

What does the ble_server loop refer to?
Do you want to use EspSystemEventLoop to do the processing currently done by handle_gap_event?

[juliankrieger]

Not only that, but couldn't the on_<event> functions make use of the Eventloop functionality?
I would be interested in opening a PR if you think it's feasible.

[taks]

For some on_<event>, the result of the callback is used in subsequent processing.
(e.g. BLECharacteristic.on_write)
The question is how to handle that process in the Eventloop.

PR is welcome.
