Refactoring the debugging output.
levels of debug output:
0 - ERROR: Only for errors.
1 - TRACE: Start of each packets and if found protocol.
2 - DEBUG: Start of searching each protocol and excluding protocols.
3 - DEBUG_EXTRA: For all other messages.
Added field ndpi_struct->debug_logging for enable debug output of each protocols.
Simple macros for debugging output are added:
NDPI_LOG_ERR(), NDPI_LOG_INFO(), NDPI_LOG_DBG(), NDPI_LOG_DBG2(),
NDPI_EXCLUDE_PROTO()
