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

redesign for better IO performance
enhanced database seek-time by avoiding write operations at distant
positions of a database file. until now, a USEDC counter was written
at the head-section of a kelondroRecords database file (which is the
basic data structure of all kelondro database files) to store the
actual number of records that are contained in the database. Now, this
value is computed from the database file size. This is either done
only once at start-time, or continuously when run in asserts enabled.
The counter is then updated only in RAM, and written at close of the
file. If the close fails, the correct number can be computed from the
file size, and if this is not equal to the stored number it is a strong
evidence that YaCY was not shut down properly.
To preserve consistency, the complete storage-routine had to be re-written.
Another change enhances read of nodes in some cases, where the data-tail
can be read together with the data-head. This saves another IO lookup during
each DB node fetch.
Includes also many small bugfixes.

- the speed was doubled by avoiding read access during the dump
- the speed was dramatically increased at least by factor 10
by using a temporary ram-file where the structures are flushed to
before it is dumped then as a whole byte-chunk to the file system.
The speed enhancements also affects some other parts of the database.
