- A shared mutex is added for synchronization
- ScopedMutexLock is used to to protect
- SoftAP: start, stop
- STA: scan, join, disconnect
- Fix switching issue between SoftAP and STA mode for primary interface
- Avoid reinit primary interface by getting mapping the current interface to the other one which is already on
- In concurrent mode, STA is the default if it is up, otherwise SoftAP is default.
- For non-concurrent mode, the most recent started interface is set as default.
