5a55397f99 some last-minute performance hacks

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

958ff4778e enhanced location search:
search is now done using verify=false (instead of verify=cacheonly) which will cause that much more targets can be found.
This showed a bug where no location information was used from the metadata (and other metadata information) if cache=false is requested. The bug was fixed.

Added also location parsing from wikimedia dumps. A wikipedia dump can now also be a source for a location search.
Fixed many smaller bugs in connection with location search.

The class still contains a potential ConcurrentModificationException which occurs when the List which contains the elements of the table of content is moified during a recursion of tagReplace(). Will try to fix this later today.

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

will loose its leading role for the re-crawl funtion when the new api tables will work. To be prepared for a replacement

1d8d51075c refactoring:
- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

after the removal of the BLOBTree, a lot of dead code appeared:
- removed dead code that was needed for BLOBTree
Some more classes may have not much use any more after the removal of BLOBTree, but still have some component that are needed elsewhere. Additional Refactoring steps are needed to clean up dependencies and then more code may appear that is unused and can be removed as well.

c079b18ee7 - refactoring of IntegerHandleIndex and LongHandleIndex: both classes had been merged into the new HandleMap class, which handles (key<byte[]>,n-byte-long) pairs with arbitraty key and value length. This will be useful to get a memory-enhanced/minimized database table indexing.
- added a analysis method that counts bytes that could be saved in case the new HandleMap can be applied in the most efficient way. Look for the log messages beginning with "HeapReader saturation": in most cases we could save about 30% RAM!
- removed the old FlexTable database structure. It was not used any more.
- removed memory statistics in PerformanceMemory about flex tables and node caches (node caches were used by Tree Tables, which are also not used any more)
- add a stub for a steering of navigation functions. That should help to switch off naviagtion computation in cases where it is not demanded by a client

99bf0b8e41 refactoring of plasmaWordIndex:
divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment

The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.

3d4b826ca5 migration of all databases that use the deprecated BLOBTree format into the BLOBHeap format. Old databases are migrated automatically.
This removes the last very IO-intensive data structures which were still used for Wiki, Blog and Bookmarks. Old database files will still remain in the DATA subdirectory but can be deleted manually if no major bugs appear during migration. There is no need for any user action, all migration is done automatically.
