Merge pull request #2400 from Nilstrieb/explicit-reexport
Use explicit re-export of `serde_derive` to give rustc more info

f42b2581da Use explicit re-export of serde_derive to give rustc more info
rustc will start looking behind `#[cfg(FALSE)]` items to start giving
better diagnostics. By using an explicit re-export instead of a glob
export, we tell rustc that `Deserialize` and `Serialize` exist here.

Eliminate special case on empty string passed to bound=""
This works just fine if we make syn parse "where " as a syn::WhereClause.

The serde(bound = "") attribute is definitely not common enough that it
would warrant a micro-optimization.

Add a test of serde(bound = "") attribute
Without serde(bound = ""), serde_derive infers a bound of `T: Serialize`
for the generated Serialize impl and `T: Deserialize<'de> + Default` for
the Deserialize impl. `X` implements none of these so the generated code
would fail to compile.
