Subject: [PATCH 1/3] Added ability to report whether a protocol is encrypted

Added new API calls
- u_int8_t ndpi_is_valid_protoId(u_int16_t protoId);
Cleaned up code and organized in a function.

- u_int8_t ndpi_is_encrypted_proto(struct ndpi_detection_module_struct *ndpi_str, ndpi_protocol proto);
Check whether a protocol is encrypted or not based on master and app protocols
