a2fa75e688 *) Asynchronous queuing of crawl job URLs (stackCrawl)
various checks like the blacklist check or the robots.txt disallow check are now
   done by a separate thread to unburden the indexer thread(s)
   TODO: maybe we have to introduce a threadpool here if it turn out that this single
         thread is a bottleneck because of the time consuming robots.txt downloads

*) improved index transfer
   The index selection and transmission is done in parallel now to improve index 
   transfer performance.
   TODO: maybe we could speed up performance by unsing multiple transmission threads in 
         parallel instead of only a single one.

*) gzip encoded post requests
   it is now configureable if a gzip encoded post request should be send on
   intex transfer/distribution

*) storage Peer (very experimentell and not optimized yet)
   Now it's possible to send the result of the yacy indexer thread to a remote peer 
   istead of storing the indexed words locally. 
   This could be done by setting the property "storagePeerHash" in the yacy config file
   - Please note that if the index transfer fails, the index ist stored locally.
   - TODO: currently this index transfer is done by the indexer thread. 
     To seedup the indexer
     a) this transmission should be done in parallel and
     b) multiple chunks should be bundled and transfered together


*) general performance improvements  
   - better memory cleanup after http request processing has finished
   - replacing some string concatenations with stringBuffers
   - replacing BufferedInputStreams with serverByteBuffer
   - replacing vectors with arraylists wherever possible
   - replacing hashtables with hashmaps wherever possible
   This was done because function calls to verctor or hashtable functions
   take 3 time longer than calls to functions of arraylists or hashmaps.
   TODO: we should take a look on the class serverObject which is inherited from hashmap
         Do we realy need a synchronization for this class?
   TODO: replace arraylists with linkedLists if random access to the list elements is not needed

*) Robots Parser supports if-modified-since downloads now
   If the downloaded robots.txt file is older than 7 days the robots parser tries to
   download the robots.txt with the if-modified-since header to avoid unnecessary downloads
   if the file was not changed. Additionally the ETag header is used to detect changes.

*) Crawler: better handling of unsupported mimeTypes + FileExtension

*) Bugfix: plasmaWordIndexEntity was not closed correctly in 
   - query.java
   - plasmaswitchboard.java

*) function minimizeUrlDB added to yacy.java 
   this function tests the current urlHashDB for unused urls
   ATTENTION: please don't use this function at the moment because
              it causes the wordIndexDB to flush all words into the
              word directory!

361f05978d Multiple updates regarding the yacy seedUpload facility,
optional content parsers, thread pool configuration ...

Please help me testing if everything works correct.

*) Migration of yacy seedUpload functionality
See: http://www.yacy-forum.de/viewtopic.php?t=256
- new uploaders can now be easily introduced because of a new modulare uploader system
- default uploaders are: none, file, ftp
- adding optional uploader for scp
- each uploader provides its own configuration file that will be 
  included into the settings page using the new template include feature
- Each uploader can define its libx dependencies. If not all needed libs are
  available, the uploader is deactivated automatically.

*) Migration of optional parsers
See: http://www.yacy-forum.de/viewtopic.php?t=198
- Parsers can now also define there libx dependencies
- adding parser for bzip compressed content
- adding parser for gzip compressed content
- adding parser for zip files
- adding parser for tar files
- adding parser to detect the mime-type of a file
  this is needed by the bzip/gzip Parser.java
- adding parser for rtf files
- removing extra configuration file yacy.parser
  the list of enabled parsers is now stored in the main config file

*) Adding configuration option in the performance dialog to configure
See: http://www.yacy-forum.de/viewtopic.php?t=267
- maxActive / maxIdle / minIdle values for httpd-session-threadpool
- maxActive / maxIdle / minIdle values for crawler-threadpool

*) Changing Crawling Filter behaviour
See: http://www.yacy-forum.de/viewtopic.php?p=2631

*) Replacing some hardcoded strings with the proper constants of the httpHeader class

*) Adding new libs to libx directory. This libs are
- needed by new content parsers
- needed by new optional seed uploader
- needed by SOAP API (which will be committed later)

f39812da91 *) 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
