It is not useful

It indicates restrictions on the ES (resolution, bitrate, codec
features...), like the H264 level

Other (audio or video) demux/codecs than real demux can use it

...as I found a case where it makes the output almost unreadable, and
cannot find another test case where it makes it better, which I'm
pretty sure I had when I did this.

This is consistent with Qt4 behaviour. This also fixes a bug when using
the configuration; the item is called "vcd", not "vcd://".

This avoids pushing and checking the mode parameter at each recursion.
Also, FindParent is now iterative.

HAVE_{LIBCDIO,LIBVCDINFO} and have_{libcdio,libvcdinfo} were nowhere
used in the source except when --enable-vcdx was given, hence only probe
for them when vcdx is to be enabled.
Since have_libvcdinfo (which is a requirement for vcdx) can only be
enabled if have_libcdio was defined, I simply put it in the enable_vcdx
block. And because vcdx needs to be explicitly enabled, we can safely
AC_MSG_ERROR on every missing library.

This reverts commit 09049343.

Sorry, I forgot to push that part

Add a helper to get the right values from the RTSP code

Calls to aout_PrepareFormat where missing.

 It fixes segfaults in src/input/stream.c (at least) when demuxers
overflow int64_t seek position, and avoid testing for negative values
everywhere.
 stream_Tell() and stream_Size() still returns signed values as too much code
depend on it.
