When generating headers from libraries that export functions as `extern "C"`
but still use namespaces (C-compatible C++ libraries), we want to generate
a Sandboxed API that includes fully-qualified namespace names as well.
In addition, we want the generated API to have the same source order as the
original library. Not only is this less surprising when reading the generated
code, it's also more accurate. Previously, we'd bundle all definitions in a
namespace and sort those alphabetically, but for code that relies on symbols
from another namespace to be available, generation will fail:
```c++
namespace zzz {
using entity_count_t = uint64_t;
} // namespace zzz
namespace sheep_counter {
using sheep_count_t = :💤:entity_count_t;
extern "C" void IncreaseSheepCounter(sheep_count_t increment);
} // namespace sheep_counter
```
