Thomas Martitz 77f19f75eb storage: Add STORAGE_HOSTFS 
CONFIG_STORAGE & STORAGE_HOSTFS allows to use parts of the storage_* API to be
compiled for application targets without compiling storage.c or performing
actually raw storage access. This is primarily to enable application targets to
implement HAVE_MULTIVOMULE/HAVE_HOTSWAP (in a later commit).

SIMULATOR uses the same mechanism without explicitely defining STORAGE_HOSTFS
(how to add a bit to an existing preprocessor token?).
