[Devel] [PATCH 01/10] CGroup API files: Rename read/write_uint methods to read_write_u64

Several people have justifiably complained that the "_uint" suffix is
inappropriate for functions that handle u64 values, so this patch just
renames all these functions and their users to have the suffic _u64.
