core, plugins file, XEP-0234, bridge: progression api enhancement:

- progressStarted have a new metadata parameter, useful to know the kind of progression, direction, etc. Check bridge doc
    - progressGetAllMetadata can be used to retrieve this data and discover on currently running progressions
    - progressFinished also have a new metadata parameter, used to e.g. indicate that hash is checked
    - core: fixed progressGetAll
    - file, XEP-0234: implemented the API modifications,  hash is returned on progressFinished
    - file: SatFile.checkSize allows to check size independently of close (be sure that all the data have been transfered though)
