Estimated hours taken: 17 Add support for invoking interactive queries to mdb. browser/interactive_query.m: New module, to implement interactive queries. browser/dl.m: browser/name_mangle.m: Copy these files from extras/dynamic_linking, since they are needed by browser/interactive_query.m. configure.in: runtime/mercury_conf.h.in: Autodetect the presence of support for dlopen() etc. browser/dl.m: Add #ifdefs so that the code will compile (but report an error at runtime) if dlopen() etc. are not supported. browser/browser_library.m: Add interface_query, dl, and name_mangle to the list of modules in this library. trace/mercury_trace_browse.h: trace/mercury_trace_browse.c: Add a new function MR_trace_query() to interface to the ML_query() function defined by browser/interfactive_query.m. trace/mercury_trace_internal.c: Add code to implement new commands `query', `cc_query', `io_query', and `mmc_options', using the MR_trace_query() function defined by trace/mercury_trace_browse.h. runtime/mercury_grade.h: Add code to define MR_GRADE_OPT, so that browser/interactive_query.m can use this to invoke mmc with the same grade that the executable being debugged was built with. doc/mdb_categories: doc/user_guide.texi: Document the new commands `query', `cc_query', `io_query', and `mmc_options'.
