sandbox: add concept of sandbox state



The state exists through the life of U-Boot. It can be adjusted by command
line options and perhaps later through a config file.  It is available to
U-Boot through state_...() calls (within sandbox code).

The primary purpose of this is to contain the "hardware" state.  It should
only be used by sandbox internal code.
