Before this commit, `fs.unwatchFile(path)` removed *all* listeners for `path`.
The function is overloaded now: `fs.unwatchFile(path)` still removes all
listeners, but `fs.unwatchFile(path, cb)` lets you remove a specific listener.
Fixes#3660.
Drop vestigial `process.installPrefix`, `node --vars`, NODE_CFLAGS and
NODE_PREFIX.
Also removed unused node_config.h.in (replaced with config.gypi a while back).

This implements server.listen({ fd: <filedescriptor> }). The fd should
refer to an underlying resource that is already bound and listening, and
causes the new server to also accept connections on it.
Not supported on Windows. Raises ENOTSUP.
