The only part of this that seems likely to be controversial is the
decision to get rid of special-case error messages, eg replace
    "could not open tablespace directory \"%s\": %m"
with the more generic
    "could not open directory \"%s\": %m"

As I said in the previous thread, I don't see anything much wrong
with that; but if anyone doesn't like it, speak now.

Also, I'm inclined to back-patch the exporting of ReadDirExtended,
so that we can rely on it being available if we use it in any
back-patched fixes.  I wouldn't back-patch anything else here that's
not a clear bug fix, but we may need public ReadDirExtended anyway
just to do that much (I didn't really check that yet).
