Currently Qemu can read from posix I/O and NBD. This patch adds a third protocol to the game: HTTP. In certain situations it can be useful to access HTTP data directly, for example if you want to try out an http provided OS image, but don't know if you want to download it yet. Using this patch you can now try it on on the fly. Just use it like: qemu -cdrom http://host/path/my.iso Signed-off-by: Alexander Graf <agraf@suse.de>

Now we can make use of the newly introduced option structures. Instead of having bdrv_create carry more and more parameters (which are format specific in most cases), just pass a option structure as defined by the driver itself. bdrv_create2() contains an emulation of the old interface to simplify the transition.
