} needed functions and headers that we actually intend to check for.

The reason the test is done this way is that if the functions are present
but the system is not configured, then it becomes very slow for zsh to
attempt YP and then fall back on other methods.

The intent is to make a best guess at whether YP is configured, and skip
it entirely if not, even if the libraries to enable it might be present.
Yes, the test may be wrong if the server is temporarily unavailable, but
this was the best compromise we could come up with at the time.

There should be some discussion of this in the zsh-workers archive from
about three years ago (maybe longer).
