Done with:
sed -i 's/{\(".*"\|NULL\), \(.*\)}/{\2, \1}/' src/mod/endpoints/mod_skinny/skinny_tables.c

and reindent

FS-3137 --resolve less of a memory leak more of a pool swelling, replaced a pool strdup that could recur with a strdup/free to avoid it

No guarantee this module still works, but it compiles again.
