* simplify tcp flag checks, fix stream_follower
On various places was used simple comparison for checking state of flags.
tcp.flags() == (TCP::SYN | TCP::ACK)
This is not what you want usually, because this check is false
in case that another flag is set also. Correct check for syn-ack
packet should be:
(tcp.flags() & (TCP::SYN | TCP::ACK)) == (TCP::SYN | TCP::ACK)
To simplify this kind of check, add new has_flags method:
bool TCP::has_flags(small_uint<12> check_flags) const
* remove duplicate TCP::SYN flag check

Performance improvements
...
* Remove option size memers on IP/TCP and instead calculate
these when they're needed
* Reorder members on IP/TCP so as to remove/decrease padding
* Move most memory helpers impl into header file so they
can be inlined
* Make PDUOption's move ctor/assignment operator noexcept
