These functions are declared static and cannot be used in others
.c source file. this commit removes the static attribute and adds
the declaration to the header for these functions.

I don't think you understood what I meant last time:

"This can easily be missed because you're exporting them in one patch
and using them in another. Do the exports in the same patch where you
use them for the first time."

Anyway, I dropped this patch and exported the functions in the
respective patches where you use the functions.
