Got GDB stub in place and working.

Looks to me like the xQueueGenericSend is getting called before the queue is initialized in station mode. I'll pick this up tomorrow evening and see if I can make any progress.

Or maybe I'll put off going to sleep a few more minutes and discover esp_event_loop_init isn't being called when not in AP mode. I'll get a PR together with this and the other STA mode fix once I get everything working end-to-end

[benvonhandorf]

Submitted PR #5. Addresses these issues and others found while getting the BMP up and running as a station.
