Progress is now also shown in percentage for Addjob, CopyJob, DeleteJob and MoveJob for archives handled by LibarchivePlugin. This was a bit tricky due to libarchive always iterating the whole archive and means that the plugin needs to know the total number of existing archive entries.

A new member variable m_numberOfEntries was added to ReadOnlyArchiveInterface, which holds the total number of entries in the archive. The variable is kept up-to-date by incrementing/decrementing it whenever the entry and entryRemoved signals are emitted by a plugin. This necessitated a slight rework of the handling of MoveJob and CopyJob by LibarchivePlugin because these emitted entry when iterating over the old entries. The new approach should also be more efficient.

The two Archive members m_numberOfFiles and m_numberOfFolders were removed.

ReadOnlyArchiveInterface::addFiles() got an additional argument of type uint that holds the number of entries to be added.

Run the four job types:

• AddJob (try adding files both to an empty archive and an existing archive)
• CopyJob
• DeleteJob
• MoveJob

And check that progress is shown in percentage in the status bar.
