So far, struct ttm_bo_global_ref was the only way of initializing a struct ttm_bo_global. Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO.

The TTM buffer-object interface provides ttm_bo_reference() and ttm_bo_unref() for managing reference counts. Replacing them with ttm_bo_get() and ttm_bo_put() aligns the API with conventions used throughout the Linux kernel. The implementation of ttm_bo_unref() clears the supplied pointer to NULL. This leads to workarounds where the caller saves the pointer's value before de-referencing the BO. ttm_bo_put() does not clear the supplied pointer.
