c10c257255 attempt to fix a deadlock situation where the IODispatcher did not work.
I suspect the dispatcher thread has crashed and queues filled so no indexing process was able to write data.
This fix tries to heal the problem, but I am unsure if it helps. To get a better view of the problem, some more log outputs had been inserted.
Added also a new attribut indexer.threads to get a control over the number of default threads for the indexer (default is 1)

138422990a - removed useCell option: the indexCell data structure is now the default index structure; old collection data is still migrated
- added some debugging output to balancer to find a bug
- removed unused classes for index collection handling
- changed some default values for the process handling: more memory needed to prevent OOM

16baa7ad24 To translate a mediawiki dump into the YaCy surrogate format do the following:
- download a wikipedia dump, i.e. dewiki-20090311-pages-articles.xml.bz2
from http://download.wikimedia.org/dewiki/20090311/
- move dewiki-20090311-pages-articles.xml.bz2 to DATA/HTCACHE/
- start the conversion; open a command shell, move to the yacy home directory and execute
java -Xmx2000m -cp classes:lib/bzip2.jar de.anomic.tools.mediawikiIndex -convert DATA/HTCACHE/dewiki-20090311-pages-articles.xml.bz2 DATA/SURROGATES/in/ http://de.wikipedia.org/wiki/

this generates a series of files to DATA/SURROGATES/in

if YaCy is running (it may run concurrently), it fetches all new dumps in the surrogate-in directory. The export process is transaction-save, that means YaCy will not start reading a dump while the dump is not completely finished.

5195c94838 two patches for performance enhancements of the index handover process from documents to the index cache:
- one word prototype is generated for each document, that is re-used when a specific word is stored.
- the index cache uses now ByteArray objects to reference to the RWI instead of byte[]. This enhances access to the the map that stores the cache. To dump the cache to the FS, the content must be sorted, but sorting takes less time than maintenance of a sorted map during caching.

538e375901 replaced old caching method for computed word hashes with a better method. The word hash computation is a new performance bottleneck (after the IO bottleneck was removed with the IndexCell data structure) and a better caching for word hashes was necessary.

c8624903c6 full redesign of index access data model:
terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash.
this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before.
Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two.
