Make it easier to print and browse I/O actions in the declarative debugger.
browser/browser_info.m:
Add a new component to the debugger's permanent state to record the
user's preference as to how many I/O actions can be printed with each
atom. If an atom has this many I/O actions or fewer, they are printed.
If it has more, only a notice about too many I/O actions to show is
printed, and the user has to look up the actions manually.
browser/browse.m:
Update the help message and the printing of the current settings
accordingly.
browser/parse.m:
Add a new piece of functionality to the "set" browser command,
"set num_io_actions <n>", that allows the user to set the value
of this new parameter.
browser/declarative_user.m:
Delete the old, undocumented command "io <action_num>". Replace with
two new command forms, "print io <from_action_num>[-<to_action_num>]"
and "browse io <action_num>". "browse io" does what the old "io"
command did, but using this to print many I/O actions is clumsy;
that's what "print io" is for.
For symmetry, also add "print <from_arg_num>[-<to_arg_num>]".
Respect the new, user-configurable limit on the number of I/O actions
printed with each atom.
tests/debugger/declarative/tabled_read_decl.{inp,exp}:
Add some tests of the new functionality.
