We should use talloc_zfree() when freeing state variables, so we
can later avoid undesirable access after free.

allocated on stack
If we provide a hostname that was allocated on stack, it may contain
invalid data in the time when it is actually resolved.
This patch fixes it.

We would only free the hostent structure itself, not its contents. Use a
wrapper provided by c-ares to do so.

ares_query does not take search or domain directives from
/etc/resolv.conf into account

In c-ares 1.7, the upstream renamed the addrttl/addr6ttl structures to
ares_addrttl/ares_addr6ttl so they are in the ares_ namespace.
Because they are committed to stable ABI, the contents are the same, just
the name changed -- so it is safe to just #define the new name for older
c-ares version in case the new one is not detected in configure time.

The in-tree SRV record parsing is used with very old c-ares libraries
that don't implement the parsing themselves (c-ares < 1.7, used in e.g.
RHEL5)
|
|
We were unscheduling the timeout handler after the first lookup
(A or AAAA) returned, but not rescheduling it if we went on to
check the secondary record type. This resulted in the resolver
never returning a result for the secondary lookup, which can mean
that logins/screen unlocks after VPN drop or suspend/resume might
never complete.

options.tries specifies the number of retries. Setting this to
zero means to try exactly once. Previously we were always trying
twice (internally). We want to simply honor the SSSD configuration
and fail over to the next server (or go offline) after one try.

We had a hard-coded timeout of five seconds for DNS lookups in the
async resolver. This patch adds an option 'dns_resolver_timeout'
to specify this value (Default: 5)

Adds a new failover API call fo_add_srv_server that allows the caller
to specify a server that is later resolved into a list of specific
servers using SRV requests.
Also adds a new failover option that specifies how often should the
servers resolved from SRV query considered valid until we need a
refresh.
The "real" servers to connect to are returned to the user as usual,
using the fo_resolve_service_{send,recv} calls.
Make SRV resolution work with c-ares 1.6

RFC 2782 defines a way to sort replies to a SRV query. In short, the
algorithm sorts all replies by priority and then does a weight-based
selection for every priority level.
For details, please see the sections "Usage rules" for overview of the
algorithm and section "The 'Weight' field" for description on the weight
selection.

This patch removes some tab-indentations from pamsrv.c, too.

Adds a new option that tells resolver which address family to prefer or
use exclusively.
