Instead of extending fsinfo_t it now holds a void * to file system specific
data. This is then setup/cleaned up by the additional of 2 additional
callbacks. Makes adding new filesystems simpler as almost no code has
to be updated in the generic makefs code now.
It doesn't need any special privileges or kernel devices.
Only ffs image creation is supported at this time, although makefs has been
designed to allow the addition of other file system formats by writing new
back-ends.
This program was designed & implemented by Luke Mewburn of Wasabi Systems.
