Jason Ish 44388f1b69 src: make include guards more library friendly
Include guards for libraries should use a prefix that is meaningful for
the library to avoid conflicts with other user code. For Suricata, use
SURICATA.

Additionally, remove the pattern of leading and trailing underscores as
these are reserved for the language implementation per the C and C++
standards.

Jason Ish d79c23baa3 dns/detect: dns.opcode keyword
Add a rule keyword, dns.opcode to match on the opcode flag
found in the DNS request and response headers.

Only exact matches are allowed with negation.

Examples:
  - dns.opcode:4;
  - dns.opcode:!1;
