library/*.m:
Delete Erlang foreign code and foreign types.
Delete documentation specific to Erlang targets.

Add pragma no_determinism_warning to allow functor_number_cc/3
to compile for now.

Discussion of these changes can be found on the Mercury developers
mailing list archives from June 2018.
COPYING.LIB:
Add a special linking exception to the LGPL.
*:
Update references to COPYING.LIB.
Clean up some minor errors that have accumulated in copyright
messages.
library/builtin.m:
Mark get_one_solution/1 and get_one_solution_io/4 obsolete.
They were once used to implement all-solutions predicates but
are now only used in the implementation of other deprecated
predicates in the builtin module.
library/solutions.m:
Make builtin_solutions, builtin_aggregate, builtin_aggregate2
actually cc_multi.
Move the promise_equivalent_solutions lie up from non_cc_call
into its callers. Delete non_cc_call.
Conform to changes.
Specifically, we now do three new checks:
BAD_DETISM: We now generate error messages for predicate declarations
that specify a determinism without also specifying argument modes.
BAD_PREDMODE: We now generate error messages for standalone mode declarations
for predicates whose predicate declaration includes modes for the arguments.
BAD_MODE_SECTION: We now generate error messages for standalone mode
declarations that are not in the same section as the predicate's (or
function's) type declaration.
compiler/hlds_pred.m:
Add a slot to the pred_sub_info. If the predicate is explicitly defined by
the user in the current module, this contains the id of the section that
contains its predicate declaration (for the BAD_MODE_SECTION check)
and whether that predicate declaration also had modes for the arguments
(for the BAD_PREDMODE check).
compiler/add_pred.m:
When adding adding new predicate declarations, perform the BAD_DETISM
check, and record the info needed for the BAD_PREDMODE and BAD_MODE_SECTION
checks.
When adding adding new mode declarations, perform the BAD_PREDMODE
and BAD_MODE_SECTION checks.

Implement the TypeCtorInfo RTTI so that generic compare
and unify work via rtti_implementation.
However after discussion with zs, this current design of
RTTI has to be adapted to become more erlang specific, due
to the different data representation on the erlang backend.
The current code will serve as a template for this new design
though, which is why it is being checked in.
Add various erlang library implementations which are
needed to run useful programs when testing the erlang backend.
compiler/elds.m:
Add a type_info_id.
compiler/elds_to_erlang.m:
We now generate type_ctor_info's so call them.
compiler/erl_rtti.m:
After discussions with zs, type_info and pseudo_type_infos
should never occur on the erlang backend as they are needed
for gc and the debugger so throw an exception for them.
Add an implementation of creating a static type_info, but which
isn't used in case we need it again later.
Create type_ctor_info with all the fields except the
TypeFunctors, the TypeLayout and the FunctorNumberMap
compiler/special_pred.m:
Make sure we generate RTTI for the builtin types.

predicates.
Various other style cleanups.

Make it an error for the (promised) purity of a foreign clause to disagree
with the declared purity of the corresponding predicate or function
declaration. We only perform this check in the absence of a
promise_{pure,semipure} pragma for the predicate or function.
Previously this situation was sometimes picked up by purity analysis but not
in all cases. For example, if a predicate was declared impure but the
foreign_proc was promised pure it wasn't reported. In that particular case
it was a problem because if the foreign_proc did not have any outputs, then
simplify.m might have optimised its body away (which is how I noticed this).
compiler/add_pramga.m:
In the absence of promise_{pure,semipure} pragmas emit error messages
about mismatches between the declared purity of a procedure and the
(promised) purity of a foreign clause for it.
compiler/mode_errors.m:
Fix a typo in an error message: s/becaise/because/
compiler/purity.m:
Fix a bug reported by Ian. Inconsistent purity annotation were being
treated as both a warning and an error. Make it into an error.

Delete the obsolete versions of the all-solutions predicates from std_util.m.
(Normally we would wait until after the 0.13 release, but we don't want them
in the next g12 release of Mercury which is why they are being deleted now.)
Document some parts of the library that are handled as special cases by the
compiler and the declarative debugger.
library/std_util.m:
Delete the obsolete versions of the all-solutions predicates from
this module.
library/solutions.m:
Mention that these predicates are handled as a special case
in browser/declarative_tree.m:
Reformat a descriptive comment so that the library reference manual
doesn't have a line that exceeds 80 characters in length.

Mention that cc_multi_equal is handled as a special case in
browser/declarative_tree.m.

compiler/const_prop.m.

Factor out the mutvars used to implement the all-solutions predicates
into their own module. For the Java backend they are also used to implement
stores.
library/solutions.m:
Delete the definition of the mutvar type and supporting predicates
from this module.
library/mutvar.m:
New module. This module provides the mutvar type that currently
lives in solutions.m (and formerly lived in std_util.m).
library/store.m:
Fix the definition of generic_mutvars for the Java backend. This
has been broken since the change that moved the all-solutions
predicate to solutions.m.
Replace ':' as a module qualifier.
library/library.m:
Add the new module.
compiler/ml_util.m:
mutvars are handled specially in the IL backend.

Move the all-solutions predicates from the library module std_util into their
own module, solutions.
Move semidet_fail, semidet_succeed, cc_multi_equal and dynamic cast from
std_util.m into builtin.m.
Add some more utility functions for performing determinism or purity casts.
(The later are primarily intended for use by solver implementors.)
library/std_util.m:
Move the all-solutions predicates into their own module, solutions.m.
For now there are (obsolete) forwarding predicates from this module to
the new one. The forwarding predicates will be included in the
upcoming 0.13 release and then removed in later versions.
Move semidet_succeed, semidet_fail, cc_multi_equal and dynamic_cast
to builtin.m
library/solutions.m:
New file. This is the new home for the all-solutions predicates.
This is pretty much cut and pasted from std_util (with module
qualifiers updated accordingly). I've rearranged the code in a more
top-down fashion as per our current coding standard.
library/builtin.m:
Move semidet_fail/0, semidet_succeed/0, cc_multi_equal/2 and
dynamic_cast/2 to this module.
Add semidet_true/0 and semidet_false/0 as synonyms for semidet_fail/0
and semidet_succeed/0.
Add impure_true/0 and semipure_true/0. These are useful for performing
purity casts, e.g. in solver implementations.
library/library.m:
Add the new module.
NEWS:
Announce the changes.
library/*.m:
Update to conform to the above.
compiler/const_prop.m:
Update evaluate_semidet_call/5 with the new module name for
dynamic_cast.
compiler/*.m:
Module qualify calls to solutions to either disambiguate them from the
versions in std_util (where they weren't module qualified) or change
the module qualifier where they were (to avoid warnings about calls to
the now deprecated versions).
tests/debugger/declarative/solutions.*:
Rename this module as the name conflicts with the new library module.
