b4f0abd97d Cancel partial downloads if the server doesn't fulfil them 
If the server doesn't fulfil a partial content request, bail out.
While at it, fix a typo.

81229329f1 Generate download clients using a builder class 
This change allows to define a proper interface for the download
client and keep its implementation completely separate. It also
allows to create clients without starting the download right away,
which could be useful when defining callbacks that require a
reference to the client.

Note that this change also drops the unused methods of DownloadClient.

5b0e37ea22 Don't use a static object as download tag 
Otherwise all the downloads will use the same tag and cancelling a
download will actually cancel all the downloads.

efa829358d Remove unknwon files that are in the downloads dir 
The files are supposed to be downloaded in a privileged location
that the user can't access. If the user wipes the data of the
application, the updates downloaded are not removed. Perform a
one-time cleanup so that our downloads dir doesn't grow without
control.

6534932b20 Show "verify" for complete INCOMPLETE updates 
INCOMPLETE is used for any update that isn't verified, even if the
file has been completed. This change is mostly needed to support
imported downloads, which we take as complete, but unverified.

b8a769eeab Remove "update name" column from the database 
It's useless since it's just the name of the file and we also stores
the full path.

cb089aa445 Don't save the URL of the update in the database 
Each update must now be in updates.json to be downloaded. Since this
file already stores the URL of each update and that the URL is not
needed after the download, the URL entry can be removed from the
database.

e6a061c090 Use a single config to define the download path 
There's no point in using a bool, just define the path.

89cb51e3dd Replace error message with debug message 
Trying to add an already added download is not error and it's
actually a way to mark an update as available online.

d327d61cc6 Send an event when update are canceled 
This allows to properly update the status of the application.
In particular, when an update is deleted:
 - Cancel the associated notification, if any.
 - Remove the entry from the controller if the update is no longer
   available online.
 - Disable the resume button if download is partially downloaded
   and is no longer available online.

08a7dfade9 Track "online updates" rather than "local updates" 
This is a preparation commit with no actual changes.

ab9ac395f0 Use deleteUpdateAsync() even if we know the file doesn't exist 
deleteUpdateAsync() is safe and it makes the code more readable at
the expense of an extra File.exists() call.

8a559103a9 Update progressbar only if it's not indeterminate 
Otherwise it can show the wrong value when it goes back to the
non-indeterminate mode (e.g. after a verification failure).

bb2f2c1005 Disable indeterminate progressbar in case of download error 
Similar to the 'paused' case, but take into account that the error
can happen when the progress is 0, in which case we just hide the
progress bar.

f0940dafca Verify package when resuming a completed download 
It's possible to resume already completed downloads. When this
happens, starts verifying the package. Otherwise we won't be
able to resume the download since the server will likely reply
with 416.

dc95edbf80 Start service to pause/resume downloads from notification 
These operations require the service, so it's better to let
DownloadService handle them. This also ensures we always fulfil
the requests, even when sent while the service is not running.
