Add `mediaOpen' function. This function mounts selected media device.

For example, you can dynamically generate and load configuration file
depending on the hardware configuration with the following template:

	mediaSetCDROM
	mediaOpen
	command='/dist/rescue/sh /dist/scripts/install.sh'
	system
	mediaClose
	configFile=/tmp/generated.cfg
	loadConfig

Now we have full access to files on the media before installation begins.
