libnetfs: add fsys_get_source
Add a user overridable function netfs_get_source with a default
implementation returning EOPNOTSUPP. Add a server function for
fsys-get-source.
* libnetfs/Makefile: Add fsys-get-source.c and get-source.c
* libnetfs/netfs.h: Add netfs_get_source.
* libnetfs/fsys-get-source.c: New file.
* libnetfs/get-source.c: Likewise.
