Add schroedinger to Fedora contrib and remove some libraries that are available in the distro itself.

THIS IS UNTESTED AND WILL probably NOT WORK.

If --syslog is specified on the commandline then vlc loads the logger in file mode first, because --file-logging is the default. This is counter intuitive for users, they expect *only* syslog mode to be active. Note that the logger module can only have one mode active at the sametime, either html, text or syslog.

We don't want to leak descriptors to child PROCESSES (!= threads) such
as the pseudo-CGI interface. The socket wrappers ahve already been doing
that for a while. Unfortunately, there are still many "leaks", through
underlying libraries, opendir(), fopen(), etc. And then, this is not
thread-safe (we leak if another thread calls fork() between open() and
fcntl()). This is a well-known limitation in POSIX anyway.

The code was never enabled.

It should fix a potential segfault when the vout is closed.
