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 tests
that check compiler error messages, expect the new line numbers.

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:

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.)

Conform to the above changes. Import the new modules where they

Fix formatting in lots of modules. Delete duplicate module
imports.

Implement a change to the mode system suggested by Ralph Becket to make use of
higher order functions a bit easier.
During mode checking of higher order calls, if the variable being called has a
higher-order function type, but only a ground inst with no higher-order
information, assume that it has the default function modes.
Also, when doing anything that might cause a variable's inst to lose higher
order mode information, report a mode error if the variable has a non-standard
higher order function mode. Situations where this may occur are at call sites,
exit sites and when merging insts at the end of a branched goal.
Note that because of this restriction, this change is not backwards compatible.
compiler/inst_util.m:
Define some predicates to check for and produce pred_inst_infos for
default function modes.
In 'inst_merge', ensure that higher order inst information is not lost
from non-standard function insts.
compiler/inst_match.m:
In 'inst_matches_initial' and 'inst_matches_final', ensure that higher
order inst information is not lost from non-standard function insts.
Also allow 'inst_matches_{initial,final,binding}' to succeed
where the first inst is a standard function inst and the
second is ground.
compiler/modecheck_call.m:
In 'modecheck_higher_order_call', if the variable to be called has no
pred_inst_info, but the correct higher-order function type, assume it
has the default function modes.
mode_util.m:
pd_util.m:
Before replacing a ground inst with 'ground(Uniq, none)', ensure that it
does not contain any nonstandard function insts.
