Non-catched jobs may have been the cause for blockings and freezes in case of overloading during strong processing

for such cases the delete() operation was introduced which is sometimes much cheaper in operation since it does not need to create objects to hold the removed content and it does not need to read those objects.

- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

This should prevent URLs with bad referrer entries from being dropped by transferURL or even crashing the whole Transmission$Chunk

pass value as byte[], not as String. This should cause that less
byte[] <-> String conversions are made during time-critical tasks.
This redesign is not yet complete, more to come ..

- reverted SVN 6766, this is too dangerous (may cause unexpected memory usage) and should not be necessary

This should speed up RWI cache dump and RWI merge operations and should cause less blocking time during these processes for the indexer.

- in all cases that the parser is entered it is a whole set of possible parsers computed according to given mime type and file extension,
that means that all parsers are considered where the registered mime acceptance and extension acceptions matches.
that may cause that several parsers are tried for the same file which will cause a success in cases where there was only the mime type was used to choose the right parser and the mime type was given wrongly by the host httpd.

- added 'select all' feature in Tables_p
- enhanced ViewFile.html: has now an input field to load arbitrary resources from the web and analyze them (!!!)
- included the ViewFile servlet into the Index Administration menu
- show in ViewFile if ressource is in url-db and/or in Web cache
- bugfixes to BEncodedHeap and Tables management

so far only search requests at the remote search interface had been counted.
This was done to protect the privacy of searchers, because counting was not done and published at the own search interface.
This caused that no search requests of robinson peers had been counted, becuase they cannot be counted at remote peer.
This change introduces a distinction of locally done search requests at the local search interface from search requests that are on the local interface but had been submitted from a remote IP without authentication.
Now 3 counters are maintained:
- partial count of remote searches
- total count of local searches on robinson peers from non-authenticated clients
- total count of local searches on robinson peers from localhost or authenticated clients
In the global statistic of search requests now the first two counters of the three cases are added
Because we habe a large number of robinson peers with a large number of remote non-authenticated requests the statistic should show at least three times of the number of search requests.
