L{formatEvent} will format an event according to several rules:
- A string with no formatting instructions will be passed straight
through.
- PEP 3101 strings will be formatted using the keys and values of
the event as named fields.
- PEP 3101 keys ending with C{()} will be treated as instructions
to call that key (which ought to be a callable) before
formatting.
L{formatEvent} will always return L{str}, and if given bytes, will
always treat its format string as UTF-8 encoded.

L{formatWithCall} is an extended version of L{str.format} that
will interpret a set of parentheses "C{()}" at the end of a format key
to mean that the format key ought to be I{called} rather than
stringified.
