Unify (and fix) the naming convention of structures (#1358)

The naming convention of the project for `struct`s is
`typedef struct x_t { } x_t`, but only if it has self-recursive
pointer members, otherwise `typedef struct { } x_t` is enough.
This patch applies this style consistently throughout the code
base.
