Hi Hugues,

Instead of hard-coding the version number of the org.slf4j.impl import
as 1.5.6 to match that exported by logback-classic, I modified the
logback-classic to export the slf4j version it uses by variable name.

Thus, in slf4j-api/src/main/resources/META-INF/MANIFEST.MF we still have
Import-Package: org.slf4j.impl;version=${project.version}
(unchanged)

and in logback-classic/pom.xml for the maven-bundle-plugin we state:

 <Export-Package>ch.qos.logback.classic*,
org.slf4j.impl;version=${slf4j.version}</Export-Package>

(instead of hard-coding the value 1.5.6).

This approach is obviously more dynamic. Unless there are unexpected
side-effects of using a lower version for the import than the actual
version of slf4j-api, due to the cyclic nature of slf4j/logback
relationship (per your patch [1] in [2]), we should keep slf4j as is
and modify logback-classic/pom.xml as described above and committed a
few minutes ago. See [3].
