[squid-dev] [PATCH] mempools-nozero part 3: wordlist

[Kinkie]

Hi,
   this patch:
- removes unused wordlistDup
- implements proper constructors for wordlist, making it MEMPROXY_CLASS-safe
- makes its destructor private to force clients to use wordlistDestroy
instead
- implements wordlistChopHead to support the one case in the whole codebase
where a wordlist element was legitimately deleted.

The code looks odd, but this is an unfortunate consequence of asymmetric
expectations on the construct/destruct side: construct side requrires C++
semantics for MEMPROXY_CLASS, destruct side callers expect C semantics.

The code has been build- and run- tested.

Patch with big context attached.
