* Add resolver functions for looking up DNS records of
various types. Currently implemented: MX, TXT, SOA, SRV, NS
* Return records as GVariant tuples.
* Make the GSrvTarget lookups a wrapper over this new
functionality.
* Rework the resolver test so that it has support for
looking up MX, NS, SOA, TXT records, and uses GOptionContext

It's a bit lame, but some of our C++ wrapping scripts expect objects to be
typedefed like:
typedef struct _FooClass FooClass;
struct {} _FooClass;
Rather than:
typedef struct {} FooClass;
Functionally they're the same, but the former makes our lives easier in the
short term
GResolver provides asynchronous (and synchronous-but-cancellable) APIs
for resolving hostnames, reverse-resolving IP addresses back to
hostnames, and resolving SRV records. Part of #548466.
