logic: indexer commands

* replaced parser arguments by project specific IndexerCommands that know everything the indexer needs to know to do its job
* added different language and project specific indexers that know how to handle a certain kind of indexer command
* refactored FileManager and FileRegister to have less overhead
* removed no-rtti restriction for clang files in lib cxx
* uncommented deprecated interprocess code.
