This is in preparation for linking test programs with both vm_utils.c and uffd-common.c. The static inline routines, while normally not a problem, in this case complicate an already fragile header file situation: the header files including other header files leads to compilation failures in a subsequent patch that moves code around. Anyway, there is no particular need for inlining here, so turn these into normal functions, as a workaround to avoid refactoring the header file includes for now.
