a83772c71b fixes and enhancements for balancer:
- crawl lists for each domain now uses a HandleSet which should use less memory than LinkedLists
- but: fill more entries into the domain lists (all available entries)
- fixes to selection criteria (best domain selection)

11639aef35 - added new protocol loader for 'file'-type URLs
- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy

98c1d65415 - show up to 10 locations (maps) after search (instead of a max of 5)
- order locations by (primary) population and (secondary) longitude (reverse ordering, both)
- added population from GeoNames, OpenGeoDB does not have that information
- changed default viewpoint of map to (30,15); shows more land and europe in the center

1defd580bc - added option to localization search to distinguish between a search for a location according to the search word only or for the relation between a web search results and locations found in the metadata fields
- used that to display two layers on map: cities and search result locations
- added many marker grafics for the display of the markers on the map
- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure

2126c03a62 - removed download-limit that can be given for the crawler for non-crawler download tasks. This was necessary because the same procedure was used for other downloads like for the download of dictionary files where a limit is not useful. The limit still stays for the indexer

789c6b26ce added a location search service: using the following servlet/example:
http://localhost:8080/yacysearch_location.kml?query=berlin&maximumTime=2000&maximumRecords=100

This will open any application that can consume kml data (which will probably be google earth) on your computer and displays the search result as positions on a map

4cd5418963 removed finalize methods because of a hint in
http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/html/memleaks.html#gbyvh

The finalize method prevents that the memory, used by the objects containing the finalize method, is collected and available for the garbage collector. Instead, the memory allocated by such classes are enqueued to a java-internal finalize queue runner. This slows down all operations that uses a lot of object containing finalize methods.

this fix does not remove all finalize method, but such that may be used for throw-away objects that are allocated many times. This should cause a better run-time performance and less OutOfMemoryErrors

7b69d79727 enhanced remove() operation: in many cases it is not necessary to return the removed object to the called.
for such cases the delete() operation was introduced which is sometimes much cheaper in operation since it does not need to create objects to hold the removed content and it does not need to read those objects.

- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

64f29f990e a collection of performance hacks and code cleanup:
- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

650be3599f added a time-out to the RWI cache to flush the cache if it has not been written for ten minutes. This additional dump criteria is necessary because some data sources repeat their vocabulary and may cause that the number of words in a RWI does not increase while the number of references in the RWI set increases. Now the RWI Buffer is flushed every 10 minutes or later if at that time already a dump is ongoing.
