948fb2ae4b Replace XXXReturn with Result<XXXSuccess, XXXError>
... in function signatures.

These breaking changes aim at improving usability by allowing users
to take advantage of Rust error management features sur as `ok_or`,
`map_err`, `expect` and the `?` operator. See the `examples` and
`tutorials` to get an idea of the impacts.

c971727193 Query: allow concrete query instantiation
Allow instantiating and dereferencing concrete queries. The motivation
for this proposal is to allow the following usability enhancements:

- Concrete queries mutability guaranteed by the borrow checker,
including for generic functions:
``` rust
    let mut p = Query::new_position(::Format::Time);
    p.get_mut_structure().set("check_mut", &true);
```

- Concrete queries functions available in place:
``` rust
    let mut q = gst::Query::new_duration(gst::Format::Time);
    let duration = if pipeline.query(&mut q) {
        Some(q.get_result())
    } else {
        None
    };
```

c99928d030 Change FormatValue related API to be more convenient to use
FormatValue is now renamed to GenericFormattedValue and the API slightly
changed. In addition there is now a FormattedValue trait, and a
SpecificFormattedValue trait plus types for Bytes, Buffers and the
existing ClockTime.

This allows to create functions like
  Pad::query_duration<F: SpecificFormattedValue>() -> Option<F>
and doesn't require the caller to unwrap the generic value anymore,
which is completely unneeded in these cases.

In addition, Segment became FormattedSegment<T> with API to
upcast/downcast between the specific formatted values and the generic
formatted value. This greatly simplifies usage of Segments.

246a54368d Clean up Query API a bit
There's now get_result() instead of get(), and separate getters for only
getting the constructor arguments of each query (otherwise query
handlers will get useless values when trying to answer a query).

c39c0c7264 Implement ClockTime as ClockTime(Option<u64>)
And also implement a FormatValue type that holds a value together with
its format to make usage of the positions/durations/seek positions/etc
more convenient and safe.
