FileSystem: Port most of the code over to using custodies.

Browse source 
The current working directory is now stored as a custody. Likewise for a
process executable file. This unbreaks /proc/PID/fd which has not been
working since we made the filesystem bigger.

This still needs a bunch of work, for instance when renaming or removing
a file somewhere, we have to update the relevant custody links.
