GOB: Add a way to reopen currently opened IMD/VMD videos
This is a workaround for how Lost in Time behaves in combination
with changes I made to the DataIO code for running Urban Runner
on low-memory devices.
Urban Runner's intro are far to big to have them copied into
memory for these devices, so I made the DataIO code return a
SafeSeekableSubReadStream into the opened archive stream instead.
Unfortunately, Lost in Time might not close a video file when it
closes the data file which it was originally in, especially when
loading a saved game. Since the video player needs to be able to
gaplessly continue a video and there does not, by itself, close
the video if not requested by the scripts, this leads to reading
out of an already closed stream in certain cases.
So, to worka round this issues, the video player tries to reopen
each currently opened video after a data archive was closed, to
make sure that that video is still available. If not, the video
is closed.
