  Logging: improve performance by not generating message unnecessarily

Avoid building an ostringstream, writing all logged values to it and converting
it to a string, for log messages that no logger is currently interested in
(e.g. TRACE logging most of the time). Cache this "lowest common log level" and
update it when any logger is reconfigured, added or removed.

  Log Message:
  -----------
  HTTPQueryDecoder::URLEncode: speed up by processing larger chunks

Scan the string for characters which need URL-encoding and append the substring
before that in one go. If the entire string does not need URL-encoding, just
return it without any further processing.
