Refactor the FileSystem API to allow for different hash functions.
Refactor the FileSystem class to include the hash function as an
instance field. This allows us to have a different hash function
per FileSystem and removes technical debt, as currently that's
somewhat accomplished by a horrible hack that has a static method
to set the hash function for all FileSystem instances.
The FileSystem's default hash function remains MD5.
