Replace the mntent emulation code with my own versions, which are GPL'd,

so that SGI can integrate them, along with the rest of the current patches,
into its own tree. The BSD license on the old code was preventing that,
as SGI's legal weasels will only allow them to accept GPL'd code.

My stuff's more well written anyway; I know how to write C++, the old author
didn't.
