035ebfbf3b - performance hacks (should affect the crawl balancer and reduce CPU load during crawl stack re-fill)

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.

0c1b29f3c9 - applied many small performance hacks
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

- removed read cache from Records data structure because the read cache had no cache hit during search operation
- copied old read-cache class to CachedRecords and the old, now new Records class does not have the cache any more and a code review checked that data structures and synchronization is clean
- removed unnecessary synchronization from Table class during get()

- added time-out wrapper for dns resolving and reverse resolving to prevent blockings
- fixed intranet scanner result list check boxes
- prevented htcache usage in case of file and smb crawling (not necessary, documents are locally available)
- fixed rss feed loader
- fixes sitemap loader which had not been restricted to single files (crawl-depth must be zero)
- clearing of crawl result lists when a network switch was done
- higher maximum file size for crawler

6388a58fc7 better memory management and slightly less (in total and temporary) RAM allocation:
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth
- changed index sorting method in such a way that it allocates less objects during quicksort
- database classes classes renaming (shorter, naming addresses that objects hold in RAM)
- added a large number of asserts to check if objects actually take the RAM that they should have
