commit a71a3374cd8cf53776c33994f69ec184c26f2129

getaddrinfo: Fix error handling in gethosts [BZ #21915] [BZ #21922]
The old code uses errno as the primary indicator for success or
failure. This is wrong because errno is only set for specific
combinations of the status return value and the h_errno variable.

getaddrinfo: In gaih_inet, use h_errno for certain status values only
h_errno is not set for NSS_STATUS_SUCCESS, so its value might not be
accurate at this point.

getaddrinfo: Properly set errno for NSS function lookup failure

getaddrinfo: Use &h_errno has the h_errno pointer
This simplifies the code because it is not necessary to propagate the
temporary h_errno value to the thread-local variable. It also increases
compatibility with NSS modules which update only one of the two places.

getaddrinfo: Use &errno has the errno pointer
Similar code in nss/getXXbyYY_r.c is already using &errno as the
argument.
