dshow: prevent division by zero

In the DShow capture module, division by zero is possible in
multiple modulo statements when dealing with granularity values
returned by capture filters.

Change the code so that:
 - if granularity is zero, then width/height/samplingrate must be
   a perfect match with requested settings.
 - if granularity is non zero, then use the old condition tests.

This fixes real crashes reported by VLC users on different forums.

Tested with both a Decklink HD Extreme card and a Decklink HD Pro card.

win32 has a fcntl header but no fcntl function

This reverts commit 9a8efe10.

As the comments says I didn't intend to push it.

This reverts commit f7f50087.

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.

This is a feature, but almost fully copied from existing avcodec code.
