4fec99115b Implementation of strategies for controlling memory resources. 
You can toggle between previous (standard) and new (generation) strategy at PerformanceMemory_p.html.
The generation memory strategy is implemented with the objective of running more robust
but with the cost of early stopping some tasks (eg. dht) while running low on memory.
This new strategy does respect the generational way a heap is organized on most used jvms.
These changes run fine on my 3 peers for weeks now, but as I'm human, I may fail.
Please be carefull using generation memory strategy and report errors by naming
OS, jvm and java_args.

d13103a0a7 changed the way how the index cache is flushed: do not flush when a put was made because that could cause that many put calls synchronize for a long time when the dump or a merge is performed. Instead a watchdog thread is doing the dump and therefore puts cannot block any more which is good when a put happens during a search result preparation.

62ac73a108 fixed bugs and deadlocks in core database indexing structures: 
- added new Array class that contains an abstraction of the java Arrrays class which replaces the home-brew quicksort algorithm.
- the new class is about four times slower than the old one, but it works correct (the old one had errors)
- fixed a synchronization problem

1912d0cccc changed handling of RowSet element retrieval: until today all elements had been copied from the underlying byte[] arrays into a new Entry object that again had a copy of a portion of that byte[] in its own bye[]. There was an option to just refer to the underlying byte[] with a pointer but that was almost never used. This commit now changes an interface to the Row class where it is now necessary to tell if a copy is always required. Fortunately the copy is only needed in very rare cases. That means that this change should cause much less memory allocation; it is expected that this happens especially during search situations.

267290a821 removed the semaphores from the cache dump process because I believe some of the semaphores may be lost somewhere which then causes that the cache is never flushed and then the peer dies from a OOM.
