User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

32bit integer overflow. The download manager will display negative download size
and speed once a file of over 2GB in size is being downloaded and has passed 2GB
of download. In my case, the download manager did not recognize the overall size
of the download file when this happened. Do not know if this bug occurs if the
download manager do know the size of the file.

Reproducible: Always

Steps to Reproduce:
1. Download a 3GB file.
2. After 2GB of download, the downloaded amount becomes negative and the speed
is negative.
3. Download finishes.

Actual Results:  
The results can be seen in the download manager.

Expected Results:  
Used long integers so that the size does not go into negative territory.
