Moved OMA downloads out of DownloadManagerService

This CL moves most of the interactions with the android DownloadManager
from DownloadManagerService to DownloadManagerDelegate. OMA downloads
use android DownloadManager, so OMA related code and shared prefs were
moved to OMADownloadHandler. The broadcast receiver for DownloadManager
was also moved to DownloadManagerDelegate.
