- made more sub-packages for search classes

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.

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'.

1d8d51075c refactoring:
- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

5bb8074150 removed the indexing queue. This queue was superfluous since the introduction of the blocking queues last year, where documents are parsed, analysed and stored in the index with concurrency.
- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

bd409fb7ba added web structure analysis for a special domain that can be requested from the api.
Example:
http://localhost:8080/api/webstructure.xml?about=www.yacy.net
returns a xml with the following content:

<?xml version="1.0"?>

67aaffc0a2 - added Latency control to the crawler:
because of the strongly enhanced indexing speed when using the new IndexCell RWI data structures (> 2000PPM on my notebook), it is now necessary to control the crawling speed depending on the response time of the target server (which is also YaCy in case of some intranet indexing use cases).
The latency factor in crawl delay times is derived from the time that a target hosts takes to answer on http requests. For internet domains, the crawl delay is a minimum of twice the response time, in intranet cases the delay time is now a halve of the response time.

- added API to monitor the latency times of the crawler:
a new api at /api/latency_p.xml returns the current response times of domains, the time when the domain was accessed by the crawler the last time and many more attributes.

b423d0a036 moved all servlets from htroot/xml to htroot/api
the file server contains a patch that temporary matches all xml paths to api,
that means all interfaces still work. Please adopt all your interfaces to the new path.
