Thanks to Srikanth Raju <srikiraju@gmail.com> for pointing out the problem.

...as the FAQ on http://libsdl.org/ declares this is the most portable
method.

There may be similar bugs in other places

Only blank discs seem to give ID_CDROM_MEDIA_STATE=blank normal audio-cds just
dont have that property at all. And instead defaulting to file, default to
invalid and return NULL if we don't find any property to tell use that optical
disc is something we are able to play currently.

Fixes udev discs sd for me, tested with empty dvd-r discs and audio cds.

-1 is a legal coordinate for a window (both in X11 and Win32).

Note that only the Qt4 provider seem to use the values this far. Also,
most window managers will move the window wherever they see fit anyway.

This reverts commit 4c40aec4.

We already check is_standalone.

These functions are just convenience so we don't need to seed the
PRNG all the time, nor to use vlc_rand_bytes() for non-security-critical
randomness.

We need the lock to read okey and ikey

This patch replaces vlc://pause:10 (only working for qt4 in complete mode)
with fake:// --fake-file=... (working in any cases)

Rightclicking on the vlc icon in systray displayed the popup menu,
but till now, there was no means to hide it without first executing
something from this menu

This patch uses leftclick as a way to hide this popupmenu

This is the POSIX linear congruential pseudo-random generator with
48-bits of state. It is non-secure/reproducible and thread-safe.
rand() is not thread-safe and *ahem* must not be used in VLC code.
rand_r() is thread-safe but obsoleted in POSIX.2008.

For secure random numbers, use the slower vlc_rand_bytes().
vlc_rand_bytes() can also be used to generate the seed if you are short
on idea for a 48-bits pseudo-random value.
