Start playback right after successfull downloading of the first segment. Switch to a higher bandwidth

This fixes this kind of scenario: you want to save a video from your
favorite video website. So you open the VLC GUI, you copy/paste the URL
into the convert dialog and you click on okay. The corresponding
playlist lua script processes the URL and a new item is added into the
playlist, but the :sout option is lost in the process, and you start
watching a video that is never saved.

This reverts commit c46366ce.

HTTP Live Streams are number from 0 in vlc_array_t. The condition in Download()
excluded 0 as valid stream. The first element in the array is at index 0, so consider
this to be valid.

If block_Realloc() fails in the function AccessDownload() then resolving
segment->data->i_buffer results in a segmentation error. Instead of continuing
when block_Realloc() has failed, just cleanup and leave the function.

This reverts commit 0861691f.

This should not be possible, probably the backtraces were corrupted.
