[libgpiod][PATCH 06/16] bindings: cxx: prepend all C symbols with the scope resolution operator

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

We explicitly resolve all global C symbols from libgpiod to the top-level
namespace. Fix it wherever its missing (mostly for C enum types).
