Add some test cases to test interactive queries.
tests/debugger/queens.inp:
Add tests of interactive queries.
tests/debugger/Mmakefile:
Add dependency of queens.out on queens.ints.
This is needed in order for us to use interactive queries.
tests/debugger/queens.m:
Export qperm/2, for use in interactive queries.
browser/interactive_query.m:
Flush MDB_stdout after printing the prompt, so things work
properly with I/O redirections.
trace/mercury_trace_internal.c:
Fix an off-by-one error detected by the above test cases.
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'.
