4daf7d475c libs: s3 and s4: make our dns lookup code signal-safe.
Cope with -1,EINTR returns. Needed as this code can be
called from inside smbd.

Also fixes a bug in not checking the return from poll()
correctly.

ad0a07c531 s3-talloc Change TALLOC_ZERO_P() to talloc_zero()
Using the standard macro makes it easier to move code into common, as
TALLOC_ZERO_P isn't standard talloc.
