pg_dump: Rename some typedefs to avoid name conflicts

In struct _archiveHandle, some of the fields have the same name as a
typedef. This is kind of confusing, so rename the types so they have
names distinct from the struct fields. In C++, the previous coding
changes the meaning of the typedef in the scope of the struct, causing
warnings and possibly other problems.
