Add events _PKGDOWNLOAD_{START, DONE, FAILED}

These will be emmitted when download a package file from a repository,
indicating that the download starts, and whether it was successfull or
not.

Note that when multiple servers are available, no event is emmitted when
switching to another server.

(This doesn't apply to alpm_fetch_pkgurl(), but since it is called by
the frontend, it shouldn't have problems knowing when the download
starts and when it ends.)
