Handle NO_OPEN/NO_OPENDIR support automatically (#949)
If the file system doesn't provide a ->open or an ->opendir, and the
kernel supports FUSE_CAP_NO_OPEN_SUPPORT or FUSE_CAP_NO_OPENDIR_SUPPORT,
allow the implementation to set FUSE_CAP_NO_OPEN*_SUPPORT on conn->want
in order to automatically get this behavior. Expand the documentation
to be more explicit about the behavior of libfuse in the different cases
WRT this capability.
