Estimated hours taken: 2.5 Branches: main Add MR_ prefixes to uses of configuration macros. Bootcheck now succeeds with MR_NO_CONF_BACKWARDS_COMPAT. Mmake.common.in: Define MR_NO_CONF_BACKWARDS_COMPAT when checking for namespace cleanliness. RESERVED_MACRO_NAMES: Remove the configuration macros. runtime/mercury_conf_bootstrap.h: Remove a duplicate definition of BOXED_FLOAT. configure.in: */*.c: */*.h: */*.m: Add MR_ prefixes.
