Estimated hours taken: 4 Clean up the handling of configuration macros in the runtime. runtime/mercury_conf.h.in: runtime/mercury_conf_param.h: Move the code to set configuration parameters based on the values of other configuration parameters from mercury_conf.h.in to a new file mercury_conf_param.h, because otherwise autoconf munges the code in undesirable ways (it replaces all `#undef <foo>' statements with `/* #undef <foo> */'). runtime/mercury_conf.h.in: runtime/mercury_conf_param.h: runtime/*.h: runtime/*.c: Use more meaningful names, starting with the usual `MR_' prefix, for various configuration parameters: - replace the existing configuration macros SPEED with three new macros MR_CHECK_OVERFLOW, MR_LOWLEVEL_DEBUG, and MR_DEBUG_NONDET_STACK; - rename DEBUG_GOTOS as MR_DEBUG_GOTOS, and make it implied by MR_LOWLEVEL_DEBUG; - rename DEBUG_LABELS as MR_CHOOSE_ENTRY_POINT. (But there are still many configuration parameters that don't start with `MR_', I'm afraid.) runtime/CFLAGSFILE: runtime/mercury_conf_param.h: Removed CFLAGSFILE. The documentation there was had rotted badly. I moved most of it to mercury_conf_param.h where hopefully it will stand a better chance of being kept up-to-date. I added documentation for the configuration parameters added in the last year or so. The documentation here now covers every configuration parameter that we use; please keep it that way! runtime/mercury_debug.h: Fix a bug: there was a misplaced "#endif". runtime/mercury_stack_trace.c: Fix yet another misspelling of "deterministic".
