[slf4j-dev] Rearranging classes

[Ceki Gülcü]

Hello John and others,

LoggerFactory class currently delegates manufacturing work to the factory 
returned by
StaticLoggerBinder. While all existing bindings distribute their own copies 
of LoggerFactory, this copy is identical, except paradoxically in logback 
version 0.9 released just a few days ago.

I propose that we include LoggerFactory in slf4j-api.jar. I think this will 
further improve our OSGi-friendliness, because we won't need to export 
partial packages in our OSGi manifests as we currently do.

In order to further simplify things, I think we should move the 
BasicMarker.java, BasicMarkerFactory.java
MarkerIgnoringBase.java, MessageFormatter.java, Util.java classes in 
package org.slf4j.impl to another package, say org.slf4j.helpers. These 
classes ship in slf4j-api.

Thus, the slf4j-api.jar would export the org.slf4j and org.slf4j.helpers 
packages and the bindings (e.g. slf4j-nop, slf4j-log4j12, etc) would export 
org.slf4j.impl package.

I'd like to emphasize that all these changes should be transparent to our 
end-users.

So, WDYT?
