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. Signed-off-by: Stephen Warren <swarren@nvidia.com>
