Create and use C API for ubiformat

[Sascha Hauer]

The USB fastboot gadget can call ubiformat when necessary. This is done
by executing the "ubiformat" command. This is not so nice since with
this the fastboot gadget needs command support enabled. This series
gets rid of this dependency by creating a C API for ubiformat.
