When a device is opened for RW closing it can trigger other actions, like udev scanning it for partition changes. Use read only for the init_* methods and RW for actual changes to the device. This adds _device_open which takes mode flags as an argument and turns linux_open into a wrapper for it with RW_MODE. _device_open_ro is added to open the device with RD_MODE and increment the open_counter. This is used in the init_* functions. _device_close is a wrapper around linux_close that decrements the open_counter and is used in the init_* functions. All of these changes are self-contained with no external API changes. The only visible change in behavior is that when a new PedDevice is created the device is opened in RO_MODE instead of RW_MODE.
