This commit ensures that all (potentially, long) filesystem activity is
performed when the user calls av_write_trailer on the DASH libavformat
context, not when freeing the context. Also, this defers media segment
deletion until after the media trailers are written.

Passes fate on LE (with "lavc/jrevdct: Avoid an aliasing violation" applied).

This reverts commit e444b3b1.
Causing build error due to rebasing. Sorry for about it.

This fixes incorrect handling of file pseudo-URIs (i.e. when the filename
starts with "file:").

When dashenc has to run for long duration(say 24x7 live stream), one can enable this option to ignore the io failure of few segment's upload due to an intermittent network issues.
When the network connection recovers dashenc will continue with the upload of the current segments, leading to the recovery of the stream.

This fixes HLS manifests being left behind if remove_at_exit is set.

The only native HLS implementation in the wild (Safari browser) doesn't
support WebM. And at least some MSE-based players (e.g. shaka-player)
cannot handle WebM media segments when playing HLS. So just skip non-mp4
streams from HLS manifests. Note that such streams will still be described
by the DASH manifest and therefore consumed by players supporting DASH.

Fixes fate-pixelutils on aix.
