[web/httpcache] send weak ETags
There's no way we can provide a strong validator in general (especially
considering how ETags are generated by the current EtagHTTPCacheManager
and EntityHTTPCacheManager). So mark our entity-tags as weak.

mysql specific registered procedures,

/* XXX limit_size version dealing with format as postgres version does.

CREATE FUNCTION text_limit_size(vfulltext TEXT, maxsize INT)
RETURNS TEXT
NO SQL
BEGIN
IF LENGTH(vfulltext) < maxsize THEN
RETURN vfulltext;
ELSE
RETURN SUBSTRING(vfulltext from 1 for maxsize) || '...';
