* fixed case where "to-index" state of a file has changed and thus the file needs to be re-indexed
* clear and re-index files that depend on changed non-indexed files
* clear and re-index files referenced by unchanged but cleared (due to referencing a changed file) files
* fixed: updated files with changed timestamp that do not have content in the db will now count as changed
* refined refresh info generator tests
* updated checklists for manual project setup tests
* implemented task for sending IndexerCommands to shared memory on demand
* SourceGroups now return IndexerCommandProviders instead of just a list of indexer commands. This way information can be stored in a compressed format
* merged IndexerCommandCxxEmpty and IndexerCommandCxxCdb
* moved sorting of indexer commands by file size from IndexerCommandList to TaskFillIndexerCommandQueue
* removed obsolete IndexerCommandList class
* wait for IndexerCommandQueue to be filled before starting the indexers
* restart finished indexer processes while indexerCommandQueue is still running
* restart indexer threads as long as there are indexer commands to process
* removed Blackboard::getMutex() and added an atomic update() method
* we don't need to get the complete compile commands for this
* as a fallback, querying a single compile command for a file is fast, because it is stored in a map
* use std::string instead of std::wstring in temp indices
* use number types for edges and source locations in temp indices
* use map::emplace where appropriate
* moved 100 occurence insert optimization fully to sqlite index
* Fixed crash when signature was wrongly recorded
* Fixed line break at wrong position for template functions/methods
* Fixed already qualified name replace with qualified name, repeating qualifiers
* added tests for java type argument recording
* implemented recording type arguments for java ExpressionMethodReferences
* changed type_argument edge to originate in generic type
* added type_usage edge for type_arguments that originates in context (e.g. calling method)
* add compiled statement for batch inserting 100 occurrences at once
* removed unnecessary primary key from component_access to get rid of additional index table
* changed explicit check for existing symbols when injecting to implicit check in insert statement (insert or ignore)
* improved performance of adding edges by replacing edge multi part index with in-memory-index
* added in-memory-index for node table
* added in-memory-index for local_symbol table
* added in-memory-index for lource_location table
* moved setting storage mode to SqliteIndexStorage, because storage modes are not used anywhere else.
* don't store current mode as member because re-creating an existing index takes no time.
* add getter for name of SqliteDatabaseIndex
* removed unused method from persistent storage
