- added chunked file transfer for non-yacy clients
- SSIs are streamed using chunked transfer, partly delivered pages can be seen in browser before transmission is finished
- added client-side network unit identification
- cleaned up code

This is a serious problem that is caused by the database bug between 0.511 - 0.513
which produced a large number of double-entries in the RWI index. The uniq()-method
tries to fix this, and it does not terminate when the index is large and the number
of double-occurrences is also large. This patch does simply implement a time-controlled
termination, which does not heal the inconsistency problem. The uniq-method itself
is correct and does not need a bugfix, the non-termination is simply caused by the large number
of data that is shifted during the process. It was possible to reproduce this behaviour
in a test environment.
A real fix would need to:
- enhance the uniq()-method by using a recursive, binary segmentation of the array to be fixed
- uniq() must report the entries that are double
- the double-entries must be deleted from the collection index (from the index and the collections) to heal the problem

- some bugs may have been fixed with wrong removal operations
- removed temporary storage of remove-positions and replaced by direct deletions
- changed synchronization
- added many assets
- modified dbtest to also test remove during threaded stresstest

- basic protection against start-up problems when database files are corrupted
- auto-delete of not-critical databases during startup when load error occurs
- on-the-fly reset option for all database tables
- automatic on-the-fly reset for seed tables during enumeration exceptions

such an entry cannot be instantiated without allocation of new byte[]; instead
it can re-use memory from other kelondroRow.Entry objects.
during bugfixing also other bugs may have been solved, maybe the INCONSISTENCY problem
could have been solved. One cause can be missing synchronization during bulk storage
when a R/W-path optimization is done. To test this case, the optimization is currently
switched off.
More memory enhancements can be done after this initial change to the allocation scheme.

- better memory allocation for FlexTable indexes
- splitting between static index and dynamic index (only the dynamic part must grow)
- to enable a merge-iteration of new splittet index, a huge number of classes needed to be adopted for new iterator classes
- added new iterator classes that support cloneable iterators
- adopted all iterator classes to implement cloneable itarators

- each cache can now allocate as much memory as is available
- no more fixed limits
- replaced old performance memory monitor by new one
- added supervision methods as static functions into the classes that provide cache functionality
- steering of ram allocation is done with two simple limits that are ram availability-relative

too large collection arrays are now avoided. By default, the biggest
collection index is 7. larger collections are dumped into a commons
directory, but cannot yet be used. Bevore doing a dump, the collection
is splittet into a part which has only root-references, and stored back
to the collection; the remaining part goes to commons

- new search options on search page
- new option in ViewInfo to display all links of a file
- enhanced collection data structure

- controlled object order for all database tables
- migrated DHT position computation to correct base64-decoded values
this also closed the 'gaps' in the dht positions

- the test phase of the new collection data structure is finished
- test data that had been generated is void. There will be no migration
- the new collection files are located in DATA/INDEX/PUBLIC/TEXT/RICOLLECTION
- the index dump is void. There will be no migration
- the new index dump is in DATA/INDEX/PUBLIC/TEXT/RICACHE

this should reduce IO a lot, because write caches are now actived for all databases
- added new caching class that combines a read- and write-cache.
- removed old read and write cache classes
- removed superfluous RAM index (can be replaced by kelonodroRowSet)
- addoped all current classes that used the old caching methods
- more asserts, more bugfixes

- generalized object caching and added new object caching class
- added object caching wherever kelondroTree was used
- added object caching also to usage of kelondroFlex
- added object buffering (a write cache) to NURLs
- added many assert statements; fixed bugs here and there
- added missing close methods to latest added classes

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.

- added generation of a compressed index within remote peers during global search
- added selection of specific urls within remote peers during secondary global search

* adopted all code to use the declaration form of kelondroRow
* fixed a bug in kelondroRow which caused wrong parsing of encoding type
* the bug caused bad database behaviour in new indexCollection data structure.
because of this bug, all test databases are now already void. A new database is created
* the kelondroFlexTable and indexCollection data structures now store a declaration of the row definition
into a properties file along the database files.

this is the new database structure that is supposed to replace the
plasmaAssortmentCluster AND the plasmaWordIndexFileCluster
The new structure is not yet active and needs to be integrated into
plasmaWordIndex. This has some migration constraints that are not yet
completely solved.

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
