and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary

The new collection index will be more generalized to support other indexes
i.e. YBR block-rank computation. A clean-up of the many conditions to support
the old database was necessary.

- removed 'deleteComplete' flag; this was used especially for WORDS indexes
- shifted methods from plasmaSwitchboard to plasmaWordIndex

- added an assortment importer. the old database structures can
be imported with
java -classpath classes yacy -migrateassortments
- modified wordmigration. The indexes from WORDS are now imported
to the collection database. The call is
java -classpath classes yacy -migratewords
(as it was)

- moved all url and index(RWI) entries to index package
- better naming to distinguish RWI entries and URL entries

- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)

The bugfix includes a migration function which starts automatically
after startup of yacy.
This applies only to you, if you are using the new collection index.

for indexing, the plasmaWordIndex.
The new data structure is ready-to-use, but currently disabled.
It can be activated by setting the static
plasmaWordIndex.useCollectionIndex
to true. This shall be done for testing purpose.
The new index is stored to
DATA/INDEX/PUBLIC/TEXT
The directory PLASMA shall be used only for crawler in the future.
Attention: during testing the data structure in INDEX may change,
and created indexes with the new data structure may get useless.

shall replace the current assortment files.
* used the kelondroFlexTable to hold the index of collections
* used kelondroRow definitions to declare all data structures
* fixed several bugs that appeared in kelondroRowSet and kelondroRowCollection during testing

* replaced indexTreeMapContainer by indexRowSetContainer
* deleted indexTreeMapContainer and abstract class
This is another step to the new database structure

to store the index entry. This is another step to move to the new database structure.
A side effect of this change is, that index storage uses much less RAM space,
which affects the index RAM cache.

indexContainers from RAM must be cloned explicitely to prevent
side-effects on stored indexContainer objects in Cache
* changed behaviour of urlReference deletion from indexContainers:
deletion does not user retrieval of all Elements from the assortments
* added textual configuration of kelondroRow and kelondroColumn definition
* update of kelondroRow usage in yacyNews
* modified kelondroAttrSeq to use modified kelondroColumn parser
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2339 6c8d7289-2bf4-0310-a012-ef5d649a1542
an iteration of key elements in kelondroTree databases is no longer supported.
this is now replaced by an iteration of kelondroRow.Entry objects from the database
Iteration of keys from the database was mostly followed by retrieval of the row
from the database, whcih caused unnecessary database load.
The index selection was also redesigned to use the new row iteration methods.
This affects many funktions, most important is the DHT selection routine which is now much faster.

* mainly for the transition to the new indexing database structure
* a bugfix for an endless loop inside kelondroTree iteration
* a bugfix for bulk read inside a kelondroTree iteration; the bug caused that some elements had been iterated twice
* very strong speed enhancement for url/domain extraction

This was done because the wordHashes iterator will get another integer
parameter and then conflicts with the wordHashes set generation

* changed status handling
* added forced cache flush when cache has containers with too high number of index entries

This was made to make it possible that RWI selections can be serialized with indexing.
Serialization will be implemented in another step.
