[Linux] os-release: unescape quotes / backslashes
The os-release specification states that single quotes, double quotes
and backslashes are supposed to be escaped with \. Unfortunately
I missed this in my original commit 7a9aa6f5d9ac8df1c79eb06ed63bce8af162c3ba.

show all removable disks mounted under /media not only mounts containing 'usb'
fixed: compile with old versions of libdbus that don't have DBUS_TYPE_UNIX_FD defined
[WIN32] update mingw runtime to 4.0.3 which contains some minor bugfixes.
[WIN32] updated libbluray to 0.4.0 (still without bd-j support yet, but with a little less hacks to build)
added: setting to disable keyboard grabbing when in fullscreen on platforms that use SDL on X11, calls SDL_WM_GrabInput(SDL_GRAB_OFF) with the SDL_FULLSCREEN temporarily zero'd, this will make SDL call XUnGrabPointer and XUnGrabKeyboard, allowing window manager keys like printscreen, volume and alt-tab to work
fixed: Video chapter seeking was flawed/broken for files handled by ffmpeg
ActiveAE: make sure sink list is not empty when settings query the default device

vdpau: clear processed pics on flush
