[PATCH] manual: Clarify NSS error reporting

This is prompted by bug 20532.  It turns out that the manual was already 
pretty clear about error-reporting requirements.

The new specification does not require that h_errnop must not be set to 
zero; I believe the variable is different from errno in this regard.

There are some inconsistencies in glibc itself about the error handling 
(not just bug 20532).  I'll see what we can do about them if this is the 
direction in which we want to go.

Thanks,
Florian
