---------------------------------------------------------

Commit be8af7f32b53401ccbda80f3245ad21121b0439f in logging-log4j2's branch refs/heads/slf4j-2.0 from Piotr P. Karwasz

[LOG4J2-2557] Remove recursion between Logger and LoggerRepository

The `Category` class constructor should not use the static method
`LogManager.getLoggerRepository()` to find the `LoggerRepository` that
created it. The value should be injected.

>          Issue Type: Improvement
>          Components: Core
>    Affects Versions: 2.11.1
>            Reporter: Robert F

> I was excited to see log4j2 supports "printf-style messages"; however, I was disappointed to learn it was not supported by the standard logging methods.
> The standard log methods do support the "{}" formatting, but not "%" formatting.  The "printf()" method is cumbersome and a longer syntax.
> Thus, I would like to see one of the following two improvements:
> 1) Have the standard log methods support both "{}" and "%" formatting.
> 2) Add methods for tracef(), debugf(), infof(), warnf(), errorf(), fatalf().
> Respectfully submitted, -RF
