* Null pointer passed as 2nd argument to memory copy function [clang-analyzer-unix.cstring.NullArg]
* Array access (from variable 'data') results in a null pointer dereference [clang-analyzer-core.NullDereference]
* bool flag to defragment CMUX payload (useful for devices that send longer messages)
* int flag to force a delay between creating virtual terminals (useful for chatty devices that send some requests)
* Fix DISC message's control field (0xFF->0xFE) to keep Poll bit cleared
* Accept UIH resp on DISC for both (0xFF, 0xFE) ignoring P/F bit
* Fix timeout processing when handling DISC message
Closes https://github.com/espressif/esp-protocols/issues/103
reworks to clear shared_ptr<> of both command and data terminals
and having DTE own it. When we swith to CMUX mode the ownership is transfered to CMux terminal
* BG96 needs a small pause between CMUX command reception and actual use
of the CMUX mode
* Correct CMUX payload reception to check FT_UIH message type (P/F flag
could be cleared or set)
