Move the univ, maybe, pair and unit types from std_util into their own
modules. std_util still contains the general purpose higher-order programming
constructs.
library/std_util.m:
Move univ, maybe, pair and unit (plus any other related types
and procedures) into their own modules.
library/maybe.m:
New module. This contains the maybe and maybe_error types and
the associated procedures.
library/pair.m:
New module. This contains the pair type and associated procedures.
library/unit.m:
New module. This contains the types unit/0 and unit/1.
library/univ.m:
New module. This contains the univ type and associated procedures.
library/library.m:
Add the new modules.
library/private_builtin.m:
Update the declaration of the type_ctor_info struct for univ.
runtime/mercury.h:
Update the declaration for the type_ctor_info struct for univ.
runtime/mercury_mcpp.h:
runtime/mercury_hlc_types.h:
Update the definition of MR_Univ.
runtime/mercury_init.h:
Fix a comment: ML_type_name is now exported from type_desc.m.
compiler/mlds_to_il.m:
Update the the name of the module that defines univs (which are
handled specially by the il code generator.)
library/*.m:
compiler/*.m:
browser/*.m:
mdbcomp/*.m:
profiler/*.m:
deep_profiler/*.m:
Conform to the above changes. Import the new modules where they
are needed; don't import std_util where it isn't needed.
Fix formatting in lots of modules. Delete duplicate module
imports.
tests/*:
Update the test suite to confrom to the above changes.

Branches: main
browser/*.m:
Replace __ with . as the module qualifier everywhere in all the modules
of the browser directory. Convert the currently tab-indented modules
to four-space indentation. Delete some unnecessary module
qualifications. Change some type names and function symbols to avoid
ambiguities. Replace a bunch of uses of DCGs with state variable
notation.

Branches: main
browser/browse.m:
browser/declarative_test.m:
browser/set_cc.m:
Conform to the convention of importing only one browser module
per line.
Estimated hours taken: 1.5
Branches: main
Implement a committed choice version of the 'set' module, and use this in
the declarative debugging oracle. This implementation of sets avoids the
use of builtin comparison, which would otherwise cause problems for the
oracle.
This fixes a bug that was causing test case 'ho5' to fail.
browser/set_cc.m:
The new module. This is mostly a wrapper around tree234_cc.
browser/mdb.m:
Make the new module a sub-module of mdb.
browser/declarative_oracle.m:
Use the new module instead of sets from the standard library.
tests/debugger/declarative/Mmakefile:
tests/debugger/declarative/ho5.exp:
tests/debugger/declarative/ho5.exp2:
tests/debugger/declarative/ho5.inp:
Enable this test case, and provide input and expected output.
