Since the bw adaptation can go really fast now,
we need to be sure to send at least 1 data segment
before switching to another.
Otherwise we'll have multiple moov bug and can
also never get any data outside of init segments.

Could be skipped as we stop parsing on moov
and index can live between moov and moof

avoids late failures

When needed (fmt->b_packetized == false), create a packetizer before creating a
decoder. The fmt_in of the decoder is copied either from the fmt_out of the
packetizer, or from the fmt of CreateDecoder.

This will allow a decoder module to be loaded/unloaded more than one time.

Use an es_format_t.

Replace it with a mutex per picture_sys_t. When doing direct rendering, the
picture_sys_t is refcounted between the vout and the decoder.

   Some Window Managers (Gnome3, Unity) will keep the task bar displayed
   and limit the fullscreen display to the subarea outside the task bar
   if the window type is not set.
   Setting the Window type to normal ensures a clean 100% fullscreen.

   This fixes an issue reported on the forum at
   https://forum.videolan.org/viewtopic.php?f=13&t=127840

Overlay lifetime can be longer than vout lifetime.

Fast switching should behave better with async commands

This reverts commit 63506d5a.

For cross renderers spu text sizing

Will never end, because the only tags permitting
differentiation from raw M3U only comes last in the playlist.

Now queues stream_Demux callbacks and data as commands
and handle es recycling when possible.

Avoids dropping data on ES/quality change.
