As above. In some places, improve comments, e.g. by expanding contractions
such as "we've". Add #ifndef guards against double inclusion around
the trace/*.h files that did not already have them.

The objective of this diff is to switch from a table of solver events built
Estimated hours taken: 32
Branches: main
The objective of this diff is to switch from a table of solver events built
into the compiler (and eventually the debugger) into a table of events
defined by a file provided by the user to the compiler, which the compiler
then records in the executable for use by the debugger.
The current design, for speed of implementation, uses temporary files parsed
by a bison-generated parser. Since the compiler needs to be able to invoke
the parser even if it is compiled in a non-debug grade, the parser is in
a new library, the eventspec library, that is always linked into the Mercury
compiler and is always linked into any Mercury program with debugging enabled
(but is of course linked only once into a Mercury compiler which has debugging
enabled).
Modify the debugger to give it the ability to print the attributes of
user-defined events (for now, only the non-synthesized attributes).
Implement a new debugger command, "user", which goes to the next user-defined
event.
configure.in:
Require flex and and bison to be available.
doc/user_guide.texi:
Document user defined events and the new debugger capabilities.
doc/mdb_categories:
Include "user" in the list of forward movement commands.
Fix some earlier omissions in that list.
runtime/mercury_stack_layout.h:
Include an event number in the user-defined event structure.
Include a string representing an event set specification in module
layout structures.
runtime/mercury_stack_layout.h:
runtime/mercury_trace_base.[ch]:
runtime/mercury_types.h
Switch from solver events to user events in names.
runtime/mercury_trace_term.[ch]:
Provide a representation of flat terms, for use in representing
the calls that generate synthesized attributes.
Ensure that exported field names have an MR_ prefix.
browser/cterm.m:
Conform to the change to runtime/mercury_trace_term.h.
scripts/c2init.in:
scripts/ml.in:
Include the eventspec library in programs compiled with debugging
enabled.
compiler/Mmakefile:
Include the eventspec library in the compiler.
compiler/options.m:
Add a new option, --event-spec-file-name, that allows the user to
specify the set of user-defined events the program may use.
compiler/handle_options.m:
Set this optimization from an environment variable (which may be
set by the mmc script) if the new option is not explicitly given.
compiler/prog_data.m:
Define the data structures for the compiler's representation of the
event set specification.
Move some definitions around to group them more logically.
compiler/hlds_module.m:
Include the event set specification as a new field in the module_info.
compiler/prog_event.m:
Add the code for invoking the parser in the eventspec library,
and for converting the simple term output by the parser to the
compiler own representation, which contains more information
(to wit, the types of the function attributes) and which has had
a whole bunch of semantic checks done on it (e.g. whether synthesized
attributes depend on themselves or on nonexistent attributes).
Provide a function to generate a canonicalized version of the event
specification file.
compiler/module_qual.m:
compiler/equiv_type.m:
Process event spec specifications as well as items, to module qualify
the names of the types of event arguments, and expanding out
equivalence types.
In equiv_type.m, rename some variables to make clear what kind of info
they represent.
compiler/mercury_compile.m:
Process the event set specification file if one has been selected:
read it in, module qualify it, expand its equivalence types, and add
to the module_info.
compiler/compile_target_code.m:
Include the event_spec library when linking debuggable executables.
compiler/call_gen.m:
compiler/continuation_info.m:
compiler/trace_gen.m:
compiler/trace_params.m:
mdbcomp/prim_data.m:
mdbcomp/trace_counts.m:
runtime/mercury_goto.h:
Generate user-defined events instead of solver events.
compiler/layout.m:
compiler/layout_out.m:
compiler/stack_layout.m:
Include a canonicalized version of the event specification file
in the module layout if the module has any user-defined events.
compiler/code_info.m:
compiler/llds_out.m:
compiler/modes.m:
compiler/modules.m:
compiler/opt_debug.m:
compiler/typecheck.m:
Conform to the changes above.
compiler/passes_aux.m:
Rename a predicate to avoid an ambiguity.
trace/Mmakefile:
Add the definition and rules required to build the eventspec library.
trace/mercury_event_scanner.l:
trace/mercury_event_parser.y:
A scanner and a parser for reading in event spec specifications.
trace/mercury_event_spec_missing.h:
Provide the declarations that should be (but aren't) provided by
flex and bison.
trace/mercury_event_spec.[ch]:
The main module of the eventspec library. Provides functions to read
in event set specifications from a file, and to write them out as a
Mercury term in the form needed by the compiler.
trace/mercury_trace_tables.c:
If the module layouts being registered include event set
specifications, then check their consistency. Make the specification
and the consistency indication available to other modules.
trace/mercury_trace_internal.c:
During initialization, if the modules contain a consistent set of event
set specifications, then read that specification into the debugger.
(We don't yet make use of this information.)
Add an extra mdb command, "user", which goes forward to the next
user-defined event.
trace/mercury_trace.[ch]:
trace/mercury_trace_cmd_forward.[ch]:
Implement the new mdb command.
trace/mercury_trace_vars.[ch]:
For user-defined events, include the attributes' values among the
values that can be printed or browsed.
trace/mercury_trace_cmd_browsing.c:
trace/mercury_trace_declarative.c:
Minor changes.
scripts/scripts/prepare_tmp_dir_grade_part:
Copy the .y and .l files to the tmp dir we use for installs.
tools/bootcheck:
Copy the .y and .l files of the trace directory to stage 2.
tools/lmc.in:
Include the eventspec library when linking debuggable executables.
tests/debugger/user_event.{m,inp,exp}:
tests/debugger/user_event_spec:
New test case to test the new functionality.
tests/debugger/Mercury.options:
tests/debugger/Mmakefile:
Enable the new test case.
tests/debugger/completion.exp:
Expect the new "user" mdb command in the completion output.

Replace the "set" command of mdb with a bunch of commands: the `format',
Estimated hours taken: 16
Branches: main, release
Replace the "set" command of mdb with a bunch of commands: the `format',
`format_param', `list_context_lines', `list_path', `xml_browser_cmd',
`xml_tmp_filename', `fail_trace_counts', `pass_trace_counts' and
`max_io_actions' commands. Each of these set just one parameter
or one of set of closely related parameters.
Move all these commands, and some existing commands that set parameters
that were elsewhere, to the "parameter" command category.
Extend some of these commands so that if given no arguments, they report
the current values of the parameters they would otherwise set.
Replace the "set" commands of the mdb browser and of the declarative debugger
with a bunch of commands: "format", "depth", "size", "width", "lines",
"actions" and "params" (the last prints the current value of the parameters).
For each category of mdb commands, create files mercury_trace_cmd_<cat>.[ch],
and move the functions dealing with that category of commands there from
mercury_trace_internal.c. Give each of these new files a logical structure
that was sometimes missing from the relevant parts of mercury_trace_internal.c.
NEWS:
Mention these changes.
doc/mdb_categories:
Document these changes.

browser/declarative_user.m:

browser/browser_info.m:
Provide some access predicates.
Update the predicate that generates mdb commands to save the persistent
state of the debugger to generate the new forms of parameter commands.
Move types and predicates for dealing with browser parameters from
