tcpopts: clean up parser -> tcpopt.c plumbing
tcpopt template mapping is asymmetric:
one mapping is to match dumped netlink exthdr expression to the original
tcp option template.
This struct is indexed by the raw, on-write kind/type number.
The other mapping maps parsed options to the tcp option template.
Remove the latter. The parser is changed to translate the textual
option name, e.g. "maxseg" to the on-wire number.
This avoids the second mapping, it will also allow to more easily
support raw option matching in a followup patch.
