This is a serious problem that is caused by the database bug between 0.511 - 0.513
which produced a large number of double-entries in the RWI index. The uniq()-method
tries to fix this, and it does not terminate when the index is large and the number
of double-occurrences is also large. This patch does simply implement a time-controlled
termination, which does not heal the inconsistency problem. The uniq-method itself
is correct and does not need a bugfix, the non-termination is simply caused by the large number
of data that is shifted during the process. It was possible to reproduce this behaviour
in a test environment.
A real fix would need to:
- enhance the uniq()-method by using a recursive, binary segmentation of the array to be fixed
- uniq() must report the entries that are double
- the double-entries must be deleted from the collection index (from the index and the collections) to heal the problem

- re-implemented index load/extend optimization that was removed from kelondroFlexTable,
this is now part of kelondroIntBytesIndex

- some bugs may have been fixed with wrong removal operations
- removed temporary storage of remove-positions and replaced by direct deletions
- changed synchronization
- added many assets
- modified dbtest to also test remove during threaded stresstest

* fixed a bug in safari (hopefully, sorry that I removed the old fix, the divs): yacy-logo is now above the fieldset, the fieldset clears and has a margin-left set
* fixed a bug with the dls: for example in ViewProfile.html the dt's (the terms/keys) had not the same height as the dd's, so the dt's were not in the same row with the coresponding dd's towards the bottom
* moved my new css-classes to the right place in base.css

* removed divide by zero bug when 20_dhtdistribution_busysleep is 0
* replaced German comment with wrong charset in source/de/anomic/plasma/plasmaCrawlBalancer.java by an English one
* replaced the table-fix for floating behind snipped images by a br with clear
* removed unnecessary old xhtml-files (were not in use, they were created when we weren't having xhtml for testing)
* new layout for image-search results: replaced the old one with spans and tables inside (not valid) with new divs, now each image snippet container has the same size
TODO:
* the ids of the snippetLoading-divs aren't valid because ids must start with an alphabetic letter or an underscore, they have to be prefixed
* in the returned snippet-xml is an unresolved pattern for status (the status is only set for text snippets)

- exclusion hand-over at remote search protocol

*) main method is generalization of main method of ymageFontGenerator:
it does not matter how many lines of how many bits a font is made of
as long as the values stay the same within the font -> use this class as
a template for your own font generators and be a happy camper
*) main method checks if font is valid (96 characters, all letters must have
same number of lines and same number of bits per line)
*) ***** I have not checked if the result is really a valid font so far. *****

Stopwords must consider experiences from our new common words and it must

such an entry cannot be instantiated without allocation of new byte[]; instead
it can re-use memory from other kelondroRow.Entry objects.
during bugfixing also other bugs may have been solved, maybe the INCONSISTENCY problem
could have been solved. One cause can be missing synchronization during bulk storage
when a R/W-path optimization is done. To test this case, the optimization is currently
switched off.
More memory enhancements can be done after this initial change to the allocation scheme.

to replace byte[] objects within kelondro. Frequent System.arraycopy are common when
kelondroRow.Entry objects are handled. This class may be used to prevent this.
However, experimental replacement of byte[] by kelondroByteArray in kelondroRow.Entry
resulted in complete re-write of large parts of kelondro. This experiment did not
completely lead to a result, because then the interface to kelondro had to be changed
also from byte[] to kelondroByteArray, which may have caused a rewrite of large parts
of YaCy. The experiment is therefore abanonded, but this class remains here without
any function but possibly for future use.
