0ff91e4451 Adapt for removal of old interfaces in libsyntax 
9108fb7bae
dropped the `map()` method (among other things) -- so we need to adapt
our code.

This change should be backwards-compatible.

4af850431c Fix deserialize_with in module with Result alias 
Result<T, E> aliases usually provide one or both of `T` and `E`. This
would cause an error when using deserialize_with:

    error: wrong number of type arguments: expected 1, found 2

which unhelpfully just pointed to `#[derive(Deserialize)]`

19ec8bbdb9 feat(codegen): Inhibit generic bounds if skip_serializing 
The generated code for a struct like:

    struct Test<A, B, C> {
        a: X<A>
        #[serde(skip_serializing)]
        b: B
        #[serde(serialize_with="...")]
        c: C
    }

Used to be:

    impl<A, B, C> Serialize for Test<A, B, C>
        where A: Serialize,
              B: Serialize,
              C: Serialize,
    { ... }

Now it is:

    impl<A, B, C> Serialize for Test<A, B, C>
        where X<A>: Serialize,
    { ... }

Both `skip_serializing` and `serialize_with` mean the type does not need to
implement `Serialize`.

40f8e6b061 feat(codegen): Add #[serde(deserialize_with="...")] 
This allows a field to be deserialized with an expression instead
of the default deserializer. This simplifies deserializing a struct
or enum that contains an external type that doesn't implement
`serde::Deserialize`. This expression is passed a variable
`deserializer` that needs to be used to deserialize the expression.

de89f95f31 feat(codegen): Add support for #![serde(skip_serialize_if="$expr")] 
This allows end users to use an arbitrary expression to decide whether
or not to serialize some field. This expression has access to all the
fields in the struct, but none of the internal state of the Serialize
implementation. For structs, serde implements this by creating a
temporary trait and implementing the struct for it. For struct variants,
the fields are copied by reference into a temporary struct first
before implementing the temporary trait.

This also fixes a bug where the serde_codegen wasn't making calls to
Serializer::serialize_{tuple,struct}_variant{,_elt}.

9812a4c9c6 feat(codegen): Allow #[serde(default="123")] 
This feature adds support for the default to be specified to be
some expression (which unfortunately needs to be parsed from
a string) without needing this value to have an implementation
of `Default`, or for a new-type wrapper in order to provide an
alternative implementation. This expression is run in a function,
and therefore has no access to any of the internal state of
the deserializer.

url-encoded parameters to a server, it might get responses back
with a different capitalization scheme. This patch restores the
behavior implemented in #62.

6d25fc9dbb feat(de): Support struct key hinting 
Formats that do not provide type hints in the serialized format
(bincode, redis) rely on hinting in the deserializer. Struct key hinting
was not previously supported. This was not an issue in the past because
bincode serializes structs as a keyless sequence of values. However,
redis data is stored (key, value, key, value, ...), and the keys must be
deserialized to properly create a struct.

The default implementation of `visit_struct_key` is simply `visit` since
that was the previous method called in codegen.

structs without the normal object wrapper. Consider types like:

```rust
struct Point {
    x: u32,
    y: u32,
}

stuct MyPoint(Point);
```

Before this patch, `MyPoint(1,2)` would get serialized as
`[{"x":1,"y":2}]`, but now it gets serialized as `{"x":1,"y"2}`.
