This field is an exact copy of `ndpi_flow_struct->detected_protocol_stack[2]`:
* at the very beginning of packet dissection, the value saved in
`flow->detected_protocol_stack` is copied in `packet->detected_protocol_stack`
(via `ndpi_detection_process_packet()` -> `ndpi_init_packet_header()`)
* every time we update `flow->detected_protocol_stack` we update
`packet->detected_protocol_stack` too (via `ndpi_int_change_protocol()`
-> `ndpi_int_change_packet_protocol()`)
These two fields are always in sync: keeping the same value in two
different places is useless.

Message length checks and basic headers are not uniform across GTP-U,
GTP-C and GTP-PRIME.
Note that, even if the length checks were wrong, the GTP sessions were almost
always correctly classified because of the "guessing" algorithm.
This patch has been tested with GTP-U, GTP-C-V1, GTP-C-V2 and GPT-PRIME-V2
traffic using ndpiReader with "-d" flag (to avoid "guessing" algorithm) and
without "-t" flag (to avoid GTP-U de-tunneling).
See #1148

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()
