DNS object, parsing, respdiff
7681d91 
- `core.object.dns`:
  - Issue DNS-OARC#39: Remove private struct and pull in `omg-dns` code
  - Issue DNS-OARC#39: Add constants and strings for class, type, opcode, rcode etc
  - Add new objects `core.object.dns.label`, `core.object.dns.q` and `core.object.dns.rr`
  - Make it possible to reuse a `core.object.dns` for parsing another payload
  - Rework the way parsing more then just the header is done:
    - Remove functions `rr_reset()`, `rr_ok()`, `rr_label()`, `rr_type()`, `rr_class()` and `rr_ttl()`
    - Remove attributes `questions`, `answers`, `authorities` and `additionals`
    - Add function `parse_q()` and `parse_rr()`
    - Payload object is now optional for `new()`
    - Change `parse()`, see documentation
  - Remove old (non-working) functions `src()` and `dst()`
  - Remove old (unused) attributes `src_id`, `qr_id`, `dst_id`, `sport` and `dport`
  - `print()` now displays textual representation of types and codes
- `core.object`: Remove prefix for constants
- `examples/*`:
  - Add `respdiff.lua`, based on `playqr.lua` but only uses `output.respdiff`
  - Remove `playqr.lua`
  - Update all examples with changes made to `core.object` and `core.object.dns`
- `README.md`/Makefiles: Remove `omg-dns` dependency
- `filter.layer`: Update parsing to use `memcpy()` and `bswap_nn()` for possible assembler optimization
- `input.fpcap`: Update parsing to use `bswap_nn()` for possible assembler optimization
- `input.mmpcap`: Update parsing to use `bswap_nn()` for possible assembler optimization
