avalon-framework-api-4.3-160000.1.1

- Split the api and impl artifacts in two different builds in order
  to break build cycle with apache-commons-logging

- Spec file cleanup

- Add alias for avalon-framework:avalon-framework and point it to
  the avalon-framework:avalon-framework-impl artifact.

- Rather use %setup/%autopatch: autosetup does not handle the
  decompression of additional sources and applying patches in the
  correct order for this package.

- Use %autosetup macro. Allows to eliminate the usage of deprecated
  %patchN.

- Do not build against the log4j12 packages, use the new reload4j

- Build against log4j12 compatibility package

- Do not require optional dependencies

- Upgrade to 4.3
  * Two source packages avalon-framework-api-4.3 and
    avalon-framework-impl-4.3 buildable both with ant
  * Make javadoc subpackage provide the manual subpackage, since
    the manual content is basically a javadoc for api
- Added patches:
  * 0001-Port-build-script-to-Maven-3.patch
    + convert the project.xml files in both sources to a valid
    maven 3 pom files.
  * avalon-framework-manifest.patch
    + Add Bundle-SymbolicName attributes to both jar files
- Removed patch:
  * avalon-framework-target.patch
    + not needed with this version

- Add maven pom files
