vfs: add [GET/SET]_COMPRESSION hooks
The VFS interfaces are sychronous, as the operations only modify
meta-data.
These hooks are dependent on support for transparent compression by the
underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST.
Support for other filesystems providing transparent comression, such as
Btrfs and ZFS, can be added in future.
The get_compression function takes fsp and smb_fname arguments. The
smb_fname argument is needed due to the current dosmode() code-path.
