This commit changes TS0710 Worker operation.
1. It introduces MessageBuffers as main
interprocess data passing mechanism.
2. DMA transaction status codes and CMUX errors
are now propagated to Service.
3. Data processing has been refactored.
Remove misleading error message(change to debug/info).
Do not trace as error multiple retry. Minimize (to zero)
error logs on cold and hot start of the phone.
Extended cmd mechanism to provide class defined responses and
implemented SMS center verification to check if SIM card is properly
cofigured and is able to send SMS messagess at all.
This check is needed because if SMS Center is lost we are not able
to send SMS messages with no verbose error codes.
Added milliseconds and noexcept specifiers for at commands
Fixed Chanel name to Channel
* option to handle response based on OK/ERROR
* better return value - Response code & response values
* common parent for common behaviour (TODO add ->cmd(...) to mux channels)
* better logging
* small fixups
