Location Info is not rigth

HI.
This bug is for Log4j 1.2.17 and I am not sure if it is also in 2.0. When org.apache.log4j.spi.LocationInfo get information of the class who write the log (looking for in the stack trace), there is two things:

1. Performance. In the constructor LocationInfo(Throwable t, String fqnOfCallingClass) is better walk from index 0 to straceTrace.length - 1 instead of in reverse. The log wrraped class is very much nearest of index 0 than index straceTrace.length - 1.

2. Bug. If the log wrapped class twice appears twice o more times in the stacktrace, you always get the first, when the right would be get the last. For this reason, you have to walk from index 0 to straceTrace.length - 1 instead of in reverse.

Regards.

P.D.: Please, it would be possible you generate log4j-1.2.18 with this fix? Thanks.
