Fix struct, union, and enum nesting in C++ 

In C, an enum or structure defined inside other structure has global
scope just like it had been defined outside the struct in the first
place.  However, in C++, such a nested structure is given a name that
is nested inside the structure.  This patch moves such affected
structures/enums out to global scope, so that code using them works
the same in C++ as it works today in C.
