1. Fix FIX-ROOT does not reconnect to router when disconnect reason is too many
2. Add API esp_mesh_print_scan_result
3. Modify not to reset mesh_xonseq of self and children when flush_upstream_packets
4. Fix not switch to a parent candidate which has the same layer and assoc as current parent
5. Fix not arm parent monitor when a parent candidate is cleared without sending an event to mesh layer
6. Fix the new voted root does not reconnect to router if rssi is weak
- ROM function uart_tx_wait_idle may have a bug which causes the function to return before the final character is fully transmitted.
This replaces uart_tx_wait_idle declaration with a static inline definition which fixes the issue.
- Also replaces the use of uart_tx_flush with uart_tx_wait_idle in esp_restart, to remove garbage in console output on restart.
- rtc_printf is temporary replaced with a no-op, pending a new release of librtc.a. Current release assumes that UART0 is used for output,
and switches UART0 baud rate while doing frequency changes and printing some log output. This doesn’t work if a different UART is used for output.
