The request log wrote the URL, User-Agent, Referer and other
request-supplied strings with no length limit, and the server accepts
headers up to 1 MiB, so one request could put about 1 MiB per field
into a log line. Every string the request log takes from the request,
including the request ID chi copies from X-Request-Id, is now cut to
the 128-byte bound the report handler already used. That bound and
its helper moved from the handlers package to the logger package so
both use the one copy.
