Clean up the debugger tests directory by (a) removing the long obsolete
*_lib files, and (b) separating out the three roles of the queens.m
into mdb_command_test.m and interactive.m as well as queens.m.
tests/debugger/mdb_command_test.m:
Add a trivial source file for this test. The other files of the test
case (.inp, .exp) already existed.
tests/debugger/queens.{m,exp,inp}:
Remove the tests of interactive functionality.
tests/debugger/interactive.{m,exp,inp}:
A renamed copy of the old queens.m, with the interactive functionality
intact. Note: since this test case is currently disabled, I cannot
be sure that the .exp file is quite correct in every detail.
tests/debugger/*_lib.*:
Removed these obsolete test cases, since for a while now we have
avoided depending on whether the library was compiled with tracing
or not by leaving all library code to the end and not printing
or stopping at any event inside library code.
tests/debugger/Mmakefile:
Make the necessary updates to accommodate the above changes.
Estimated hours taken: 3
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.
