If explicitly set, the C{isError} key will be preserved when forwarding

regardless of log level.

The new-style C{"log_level"} key is not translated to the old-style
C{"logLevel"} key.
Events are forwarded from the old module from to new module and are
then seen by old-style observers.
We don't want to add unexpected keys to old-style events.

If a stdlib log level was provided as a string (eg. C{"WARNING"}) in
the legacy "logLevel" key, it does not get converted to a number.
The documentation suggested that numerical values should be used but
this was not a requirement.

The old-style C{"message"} key is added, even if no new-style
C{"log_format"} is given, as it is required, but may be empty.

Formatting is translated such that text is rendered correctly, even
though old-style logging doesn't use PEP 3101 formatting.
