[BZ #11000]
* nis/nss_nis/nis-hosts.c (_nss_nis_gethostbyname4_r): Always set
*herrnop before returning.
* nis/nss_nisplus/nisplus-hosts.c (internal_gethostbyname2_r):
Likewise.
* nss/nss_files/files-hosts.c (_nss_files_gethostbyname4_r): Handle
TRYAGAIN errors separately.
* sysdeps/posix/getaddrinfo.c (gaih_inet): Fix error handling of
*name4_r after functions.
