0cbda0b2b8 - replaced all length() == 0 and size() == 0 with isEmpty()
- replaced some length() > 0 and size() > 0 with !isEmpty() - cannot be
done automatically
- implemented some isEmpty() methods

41c02cb10e - less restrictions for usage of Table RAM copy
- new limit to use the table copy (instead of flag): 400MB available. If
less is available, then a copy is never used. If more is available, then
it can be used if there is a remaining space of at least 200MB
- flush caches more often: flush the Digest cache

transmitted to remote peers. This will be used for private index copies

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

31283ecd07 - added a search option to filter only specific network protocols. i.e. get only results from ftp servers. Just add '/ftp' to your search.
for example search for "passwd /ftp". This can also be done with /http /https and /smb
- fixed some search throttling processes that should protect your peer against search DoS or strong search load

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'.

0d363a94d7 more performance hacks
this makes YaCy search results VERY fast for all verify=false search cases
and it enhances the search speed also for all other snippet-fetch cases.
With this change my peer performed 100 Queries Per Second (!!!) while doing 10 queries simultanously (!!!)
in an intranet index of 20000 URLs on my 16-core Mac

Check this yourself by doing:
cd bin
./searchtestmulti.sh
after finishing the run, divide 1000 by the given time per query (which is the qps for one thread)
and then multiply again by 10 (because 10 search threads has been started)

37b8827a7a - removed the UPnP library sources from sbbi and added the jar library again. The library was included to get support for fedora releases, but after this time the fact that the sbbi cannot be part of fedora should be re-discussed. If this will still not be possible, then we may integrate the sbbi UPnP package using reflection.
- cleaned uo the code. The new eclipse helios provided new warnings for dead code. This change cleans up most of these warnings

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
