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.

e804ef4d76 Switch to Rust 1.31 as minimum supported version
Too many dependencies switched and we can't really keep everything at an
older version.

Commented out for now until stable becomes 1.32.

Examples: Pin some dependencies to builda with rustc 1.28
These dependencies require rustc 1.31, which we can't yet use.
Since they are only affecting examples its not a big deal to pin
them to an earlier version.

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).
