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'.

d607b30b6a performance enhancements for search and code review for database functions
- 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()

2c549ae341 fixed a number of small bugs:
- better crawl star for files paths and smb paths
- 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

83ac07874f - corrected return value of put() methods (not used anywhere, so it did not harm before)
- added use of LookAheadIterator which should prevent mistakes when coding iterators with embedded iterators

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

1defd580bc - added option to localization search to distinguish between a search for a location according to the search word only or for the relation between a web search results and locations found in the metadata fields

- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure

7b69d79727 enhanced remove() operation: in many cases it is not necessary to return the removed object to the called.
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.

64f29f990e a collection of performance hacks and code cleanup:
- 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
