src: revisit tcp options support
Rework syntax, add tokens so we can extend the grammar more easily.
This has triggered several syntax changes with regards to the original
patch, specifically:
tcp option sack0 left 1
There is no space between sack and the block number anymore, no more
offset field, now they are a single field. Just like we do with rt, rt0
and rt2. This simplifies our grammar and that is good since it makes our
life easier when extending it later on to accomodate new features.
I have also renamed sack_permitted to sack-permitted. I couldn't find
any option using underscore so far, so let's keep it consistent with
what we have.
