59b767eebd stop loading via http at defined maximum of bytes - even size is unknown before loading
using max-file-size of type int for parsing documents
(since content is used as byte-arrays, 'integer' should be maximum)

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.

a563b05b60 enhanced crawler:
- added a new queue 'noload' which can be filled with urls where it is already known that the content cannot be loaded. This may be because there is no parser available or the file is too big
- the noload queue is emptied with the parser process which indexes the file names only
- the 'start from file' functionality now also reads from ftp crawler

ffaa9a1c51 avoiding double-loading of the same resource from the web in case that a seond attempt to load the resource is started while the first attempt is still loading the content from the web. This will delay the second attempt to the time when the first attempt has finished with the possible result that the second attempt reads only from the web cache, not from the web.
This will also enhance the process of image result display from SVN 7105

22dbbcfa56 better (and corrected) recognition of intranet and internet-addresses. This corrects the isLocal property that is used by network definitions to restrict index ranges to local and global addresses. Address locations (intranet or internet) had been partly identified by the top level domain of the host address. Since intranet addresses can also be addressed using a host name that is in a country domain it is necessary to do a dns resolving for each check. The check is supported by a local dns cache so the intranet/internet check should not affect network traffic too much. To ensure that the cache works properly the cache class was upgraded to better concurrency data structures.

b6fb239e74 redesign of parser interface:
some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

7bcfa033c9 more abstraction of the htcache when using the LoaderDispatcher:
a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

87087f12fe - scanned remote search process and enhanced some data structure and synchronizations here and there
- removed concurrency overhead for small number of index normalizations as it happens during remote search
- removed 'load only parseable' constraint for snippet fetch because some resources may not have any url file extension and these had therefore not been parseable and searcheable since they may become parseable after loading when their mime type is known
- this partly fixes some problems with http://forum.yacy-websuche.de/viewtopic.php?p=20300#p20300 but more changes are necessary to get all expected search results
