      go.net/publicsuffix: tighten the encoding from 8 bytes per node to 4. · 0f34b776
      Nigel Tao authored 
      On the full list (running gen.go with -subset=false):

Before, there were 6086 nodes (at 8 bytes per node) before. After,
there were 6086 nodes (at 4 bytes per node) plus 354 children entries
(at 4 bytes per node). The difference is 22928 bytes.

In comparison, the (crushed) text is 21082 bytes, and for the curious,
the longest label is 36 bytes: "xn--correios-e-telecomunicaes-ghc29a".

All 32 bits in the nodes table are used, but there's wiggle room to
accomodate future changes to effective_tld_names.dat:

The largest children index is 353 (in 9 bits, so max is 511).
The largest node type is 2 (in 2 bits, so max is 3).
The largest text offset is 21080 (in 15 bits, so max is 32767).
The largest text length is 36 (in 6 bits, so max is 63).

      The tables were generated by:

go run gen.go -subset -version "subset of publicsuffix.org's effective_tld_names.dat, hg revision 05b11a8d1ace (2012-11-09)"       >table.go

go run gen.go -subset -version "subset of publicsuffix.org's effective_tld_names.dat, hg revision 05b11a8d1ace (2012-11-09)" -test >table_test.go

The input data is subsetted so that code review is easier while still
covering the interesting * and ! rules. A follow-up changelist will
check in the unfiltered public suffix list.

Update golang/go#1960.
