From 20c136159b37f11822b591941c077bb2be6ede05 Mon Sep 17 00:00:00 2001

Subject: [PATCH 20/42] libparted: Fix warnings from GCC 8
-Wsuggest-attribute=pure
As GCC 8 suggests, add 'pure' attribute to 17 functions. After adding
pure attributes, GCC suggested three more functions to add pure
attributes. Add pure attribute to those functions also. In total, add
pure attributes to 20 functions.
I read code of the functions and confirmed the 20 functions are pure:
they have no effect except the return value, and their return value
depend only on the parameters and/or global variables.
