fs: add filesystem switch libary, implement ls and fsload commands
Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load},
and transparently handle either file-system. This scheme could easily be
extended to other filesystem types; I only didn't do it for zfs because
I don't have any filesystems of that type to test with.
Replace the implementation of {fat,ext[24]}{ls,load} with this new code
too.
