[PATCH] SBufList

Hi,
  attached is v1 of SBufList. Its purpose is to be the eventual heir
to wordlist. For this reason I've implemented the bare minimum API to
cover wordlist's API, and kept code to a minimum by making it a
typedef of std::list.

The patch is missing Makefile.am integration, it's a cherrypick of
lp:~squid/squid/stringng. I'll hand-merge Makefile.am if the code is
accepted.

The only remaining bit of that branch is the tokenizer. As Alex
mentioned he's going to draft an API for that, it's quite likely that
if the two patches I'm proposing today and Amos' SBuf-based String
reimplementation are accepted, then this branch can (finally) be
closed, and the chase can begin for having clients use StringNG.

Thanks,
