_Library names are not necessary._

## Description

The analyzer produces this diagnostic when a `library` directive specifies
a name.

## Example

The following code produces this diagnostic because the `library`
directive includes a name:

```dart
library [!some.name!];

class C {}
```

## Common fixes

Remove the name from the `library` directive:

```dart
library;

class C {}
```

If the library has any parts, then any `part of` declarations that use
the library name should be updated to use the URI of the library instead.
