DownloadProvider: add to support pause/resume download by manual

This feature contains below points:
1. add to pause running download by manual.
2. add to resume manually paused download by manual.
3. add to show proper contents in notification and download-list
   for manually paused status.
4. add to support download breakpoint continuing when HTTP server
   doesn't contain etag in response header. Android baseline only
