ccc3760a47 Refactoring and redesign of data architecture to make URIMetadataRow
superfluous. The target is to make a solr document as the core of YaCy
documents which would cause that many conversions can be removed. On the
way to this target the Equivalence of URIMetadataRow and URIMetadataNode
had to be removed to expose the usage of the old URIMetadataRow data
structure.
This refactoring already removes unneccessary conversions and should
make memory usage during indexing lower.

5f0ab25382 removed the option to prevent removal of & parts inside of the
MultiProtocolURI during normalform computation because that should
always be done and also be done during initialization of the
MultiProtocolURI Object. The new normalform method takes only one
argument which should be 'true' unless you know exactly what you are
doing.

10da7335ea performance hack: use a hash cache for all hashes that are computed by a
byte array. If this hash is used in a HashMap (which is very often the
case) then this hack eliminates a lot of re-computations of the same
hash.

0bcef2d156 added feature as requested in
http://forum.yacy-websuche.de/viewtopic.php?f=18&t=3461
The search can now be configured with a non-display host list.
the search will always exlude the given list of host unless they are
requested directly using the host navigation

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'.
