Remote Console: Enhancements

Browse source 
- Accept input comments
 - Allow leading and trailing spaces in remote console input commands
 - Force prompt to be "sim> " or "SIM> " when in a master mode console session. "SIM> " used during single command mode.
 - Enhance performance of single command mode input processing by processing all available input characters before actually flushing output buffers

TMXR API extension to add tmxr_input_pending_ln that reports the existence of additional input data

TMXR also now conforms to revised sim_sock API changes
