Extract filepair_cb from ui-patch.c
Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to filepair_cb_raw(). This callback will be used in ui-diff.c in a follow-up patch. Note that it is not straightforward to extract filepair_cb() from ui-diff.c which is why it is not done here as well. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
