Rename forward-compatible ResultStatement interfaces to Result

UPGRADE.md

 # Upgrade to 2.11
 
+## Deprecated `ResultStatement` interface
+
+The `ResultStatement` interface is deprecated. Use the `Driver\Result` and `Abstraction\Result` interfaces instead.
+
 ## Deprecated `FetchMode` and the corresponding methods
 
 1. The `FetchMode` class and the `setFetchMode()` method of the `Connection` and `Statement` interfaces are deprecated.
-2. The `Statement::fetch()` method is deprecated in favor of `fetchNumeric()`, `fetchAssociative()` and `fetchOne()`.
-3. The `Statement::fetchAll()` method is deprecated in favor of `fetchAllNumeric()`, `fetchAllAssociative()` and `fetchFirstColumn()`.
-4. The `Statement::fetchColumn()` method is deprecated in favor of `fetchOne()`.
+2. The `Statement::fetch()` method is deprecated in favor of `Result::fetchNumeric()`, `::fetchAssociative()` and `::fetchOne()`.
+3. The `Statement::fetchAll()` method is deprecated in favor of `Result::fetchAllNumeric()`, `::fetchAllAssociative()` and `::fetchFirstColumn()`.
+4. The `Statement::fetchColumn()` method is deprecated in favor of `Result::fetchOne()`.
 5. The `Connection::fetchArray()` and `fetchAssoc()` method are deprecated in favor of `fetchNumeric()` and `fetchAssociative()` respectively.
-6. The `StatementIterator` class and the usage of a `Statement` object as `Traversable` is deprecated in favor of `iterateNumeric()`, `iterateAssociative()` and `iterateColumn()`.
+6. The `StatementIterator` class and the usage of a `Statement` object as `Traversable` is deprecated in favor of `Result::iterateNumeric()`, `::iterateAssociative()` and `::iterateColumn()`.
 7. Fetching data in mixed mode (`FetchMode::MIXED`) is deprecated.
 
 ## Deprecated `Connection::project()`
