Embrace anonymous unions.

Several OVS structs contain embedded named unions, like this:

struct {
    ...
    union {
        ...
    } u;
};

C11 standardized a feature that many compilers already implemented
anyway, where an embedded union may be unnamed, like this:

struct {
    ...
    union {
        ...
    };
};

This is more convenient because it allows the programmer to omit "u."
in many places.  OVS already used this feature in several places.  This
commit embraces it in several others.
