735e2737e3 * added index segments
This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

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.

ce1adf9955 serialized all logging using concurrency:
high-performance search query situations as seen in yacy-metager integration showed deadlock situation caused by synchronization effects inside of sun.java code. It appears that the logger is not completely safe against deadlock situations in concurrent calls of the logger. One possible solution would be a outside-synchronization with 'synchronized' statements, but that would further apply blocking on all high-efficient methods that call the logger. It is much better to do a non-blocking hand-over of logging lines and work off log entries with a concurrent log writer. This also disconnects IO operations from logging, which can also cause IO operation when a log is written to a file. This commit not only moves the logger from kelondro to yacy.logging, it also inserts the concurrency methods to realize non-blocking logging.

3d4b826ca5 migration of all databases that use the deprecated BLOBTree format into the BLOBHeap format. Old databases are migrated automatically.
This removes the last very IO-intensive data structures which were still used for Wiki, Blog and Bookmarks. Old database files will still remain in the DATA subdirectory but can be deleted manually if no major bugs appear during migration. There is no need for any user action, all migration is done automatically.

1779c3c507 - added a read cache to the RAFile interface to RandomAccessFile
- added a write buffer to BLOBHeap
- modified the BLOBBuffer (is now only to buffer non-compressed content)
- added content compression to the HTCache
The new read cache will decrease the start/initialization time of BLOB files,
like the HTCache, RobotsTxt and other BLOBHeap structures.

536e77e8b7 modifications towards a single database operation to read/write http header and cached file at once:
- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

7b1c9e6aee discovered and removed a (possibly large) memory leak:
many classes used the kelondroMapDataMining (was: kelondroMapObjects) which adds statistical
functions to the kelondroMap (was: kelondroObjects), but these functions were not used by these
classes. Especially the HTCACHE and robots.txt database allocate a very large number of objects
for statistical use, but never used them. By replacing the kelondroMapDataMining with the
kelondroMap object for these classes now less memory is allocated.
