*) Some performance improvements

- many classes set to final
- implementation of a session-thread pool
- reusage of the server handler class (normally the httpd object)
  within the session thread
- implementation of a httpc object pool
- introduction of a linebuffer in httpd which can be reused
- reusing the properties table in the httpc
- added to apache libs (commons-collections, commons-pool) which 
  are needed for the object/thread pool implementation
