Refactor filesystem types list and fix bug.

Refactor the management of the filesystem types list (vfsconf) by
introducing some management functions. Reduce inter-module coupling.

This actually fixes a potential "bug" in vfs_register() which does not
compare the new VFS to register with the last entry from the list, i.e.
two (or more) sequential vfs_register() calls with the same argument
would succeed.
