* make uart_communication(), storeCommand() and getCommand() static in comms.c * move receiver thread creation and respective mutexes to comms.c * add mutex and signal for tx buffer * use comms.c for flasher as well * remove comm functions from client/proxmark3.h * this completes isolating all USB communication related functions in comms.c * don't assume a port to be defined by a name. Change parameter in OpenProxmark() to void* * comms.c: set sp and serial_port_name to NULL when offline
