input: name input event structs

Some input event structs contain enums, whose values can be accessed
globally in C, but need a qualified access in C++. Since these enums are
defined inside unamed union and structs, there was no way to use them
from C++ code.

To avoid the problem, declare named structs for every event type
requiring more than one field.
