Subject: [PATCH] dvr: Persist dvr entry filename upon creation.

Previously we added the filename to the dvr_entry at the start of the
recording, but did not persist it. This meant that if tvheadend
crashed before the programme completed then we would leave a file on
disk which is not referenced by any recording, hence will never be
deleted.

So we persist after the file is created/stream opened. This entry then
has filename, stream info, and (actual) start time, but no (actual)
stop time.
