Introduce event types for start/end database list download

Multiplexed database/files downloads will use multiple progress bars.
The UI logic is quite complicated and printing error messages while
handling multiple progress bars is going to be challenging.

Instead we are going to save all ALPM error messages to a list and flush
it at the end of the download process. Use on_progress variable that
blocks error messages printing.
