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.

123375bfba added a new yacy protocol servlet 'idx'. This returns an index to one of the data entities that is stored in YaCy.
This servlet currently only serves for indexes to the web structure hosts. It can be tested by calling
http://localhost:8090/yacy/idx.json?object=host
This yacy protocol servlet is the first one that returns JSON code and that also shows index entries in a readable format. This will make the development of API applications much easier. This is also an example implementation for possible json versions of the other existing YaCy protocol interfaces.

The main purpose of this new feature is to provide a distributed block rank collection feature. Creating a block rank is very difficult if the forward-link data is first collected and then one peer must create a backward-link index. This interface provides already a partial backward index and therefore a collection of all these indexes needs only to be joined which is very easy. The result should be the computation of new block rank tables that all peers can perform.

To reduce load from peers this servlet buffers all data and refreshes it only once in 12 hours. This very slow update cycle is needed because the interface will be called round-robin from all peers once after start-up.

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)
