The define PR was introduced to switch quickly between TRACE levels
for specific debug print messages.
Now, it all became debug output, since it is not needed in normal
operation.
* Sniffer uses phone endpoints for communication and the ringbuffer
routines the phone communication uses
* Most times the Usart1 interrupt is not triggered, and therefore
no values are recorded
* ISO7816_Init: Takes Usart_info and CLK_SLAVE/CLK_MASTER as param
* ISO7816_SendChar, ISO7816_GetChar: Usart_info is passed
* ISO7816_Set_Reset_Pin function for CCID part
* iso7816_4.c: BOARD_ISO7816_BASE_USART replaced by USART_SIM
* Redundant _ISO7816_Init, _ISO7816_SendChar, _ISO7816_GetChar
functions removed
* All simtrace modes use iso7816_4.c functions instead of redefined
_ISO7816_xxx functions
* Implemented configure, init, exit functions:
When a configuration is changed, interrupts for reset pins
should be disabled
* Moved variables shared between code files to simtrace.h
