Commit Message

ares_init_options: only propagate ENOMEM error

Commit 46bb820be3a8 ("ares_init_options: don't lose init failure")
changed init behaviour so that earlier errors in initialization
weren't lost.  In particular, if the user passes in specific
options but they are not applied because of an allocation failure,
that failure needs to be reported back to the user; this also
applies when duplicating a channel with ares_dup().

However, if init_by_resolv_conf() fails with a different error than
ARES_ENOMEM (typically ARES_EFILE), the previous behaviour of
overwriting and forgetting about that earlier failure is still OK.

So restore the previous status-overwriting behaviour, but only if
there is no pending ENOMEM error.

Fixes issue 60.
