    Make these tests use four-space indentation, and ensure that
    each module is imported on its own line. (I intend to use the latter
    to figure out which subdirectories' tests can be executed in parallel.)

    These changes usually move code to different lines. For the debugger tests,
    specify the new line numbers in .inp files and expect them in .exp files.

Estimated hours taken: 3
Branches: main

When the user asks for the printing of a non-existent part of a term, make
mdb print the path up to the nonexistent part as part of the error message.

trace/mercury_trace_var.[ch]:
	Give to the function that generates those error messages a pointer
	not just to the bad part of the path, but to the full path as well,
	so it can print the good part.

	Remove fixed limits on the size of error messages.

trace/mercury_trace_spy.c:
	Conform to the change in mercury_trace_var.h.

runtime/mercury_memory.[ch]:
	Provide a mechanism for dynamically resizing character buffers
	for use by mercury_trace_vars.c. We use this instead of snprint
	because snprint isn't available or doesn't work properly on some
	platforms.

	Document a previously overlooked function.

tests/debugger/browser_test.exp3:

	Update these test cases to expect the new, more informative

8576975c4e Implement breakpoints on user events. Users may specify an event set,
Estimated hours taken: 20
Branches: main

Implement breakpoints on user events. Users may specify an event set,
an event name, both, or neither. Four forms of the mdb "break" command
create such breakpoints:

	break [the usual options] user_event <event_name>
	break [the usual options] user_event <event_set_name> <event_name>
	break [the usual options] user_event_set
	break [the usual options] user_event_set <event_set_name>

In addition, the command

	break [the usual options] user_event

is also accepted, as a synonym for

	break [the usual options] user_event_set

Since user events are not interface events or entry events, add a new, simple
ignore specification, which decrements the ignore count on every match of the
event.

Make the "break_print" mdb command consistent with the other command that
operates on existing breakpoints ("condition") by making it apply by default
to the most recently created breakpoint.

Make "condition" and "break_print" use the same option letter (-b) to introduce
the breakpoint number.

Fix a bug in the implementation of "break_print" that led to printing out
the selected variable, but not the selected *path* within the selected
variable. The reason was that we recorded what to print (variable spec plus
path) in a string, but that the process of using that record to print out
what was wanted destroyed the string (by putting a NULL between the variable
specification and the path), so that *later* uses of that string would find
an empty path. The fix is to record a var_spec/path pair in the print list.

Fix some slightly misleading output: when printing part of a variable, we
printed the name of the variable without any indication that the value printed
wasn't the whole value of the variable. We now print the path as well.

doc/user_guide.texi:
	Document the changes above.

	Document the usage "break_print [options] none", which we have always
	supported, but which was not documented.

runtime/mercury_stack_layout.h:
	Add a utility macro.

trace/mercury_trace.c:
	Fix a bug which left a variable uninitialized.

trace/mercury_trace_cmd_breakpoint.c:
	Implement the new command forms and options described above.

trace/mercury_trace_spy.[ch]:
	Implement data structures for keeping track of the new forms of
	breakpoints, and add the necessary functions for manipulating them.
	Update the function that checks whether the current event matches.
	Factor some common code out of that function, as well as out of the
	functions for adding new breakpoints.

	Change the print list data structure as described above.

	Add some utility functions.

	Add MR_ prefixes to the names of structure fields that previously
	lacked them.

trace/mercury_trace_cmd_misc.c:
	Handle the new breakpoint types.

trace/mercury_trace_tables.c:
trace/mercury_trace_internal.c:
	We used to parse the event set descriptions in module layout structures
	when the debugger was initialized (in mercury_trace_internal.c).
	However, we delay registering all the modules until this is needed,
	so at that time we don't yet *have* the list of module layout
	structures, so we used to parse nothing. This diff moves the code
	for doing the parsing to the time when the module layout structures
	are registered (in mercury_trace_tables.c).

	Don't test whether the module layout structure contains the fields
	for user event descriptions, since that diff has been installed on
	all our systems weeks ago.

trace/mercury_trace_internal.c:
	Conform to the new print list structure.

trace/mercury_trace_vars.[ch]:
	Print any selected path together with a variable name when printing a
	value. (This is the last bug fix mentioned at the top.)

	Export a function for use in mercury_trace_internal.c.

	Add some utility functions.

	Improve some error messages.

trace/mercury_trace_tables.h:
	Add a const qualifier.

tests/debugger/user_event.{inp,exp}:
	Extend this test case to test the new functionality.

tests/debugger/breakpoints.{inp,exp,exp2}:

	Rename a predicate to make clear the restriction on its use,

	Add a predicate for creating simple tests.

	Add a utility predicate for setting the context of a goal directly.

compiler/modules.m:
	Include dummy types interface files, even if they are private to the
	module. This is necessary because with the MLDS backend, the generated
	code inside the module and outside the module must agree whether a
	function returning a value of the type returns a real value or a void
	value, and this requires them to agree on whether the type is dummy
	or not.

	The impact on interface files is minimal, since very few types are
	dummy types, and changing a type from a dummy type to a non-dummy type
	or vice versa is an ever rarer change.
