This should make error messages easier to read by removing clutter.
compiler/error_util.m:
Split each of the sym_name and sym_name_and_arity error pieces into two;
one which prints any module qualification present in the given sym_name,
and one which does not. This forces people who use these pieces
to think about whether they want the sym_name module qualified
in the error message or not.

Conform to the change above. For sym_name references for which
the module qualifier is obvious (usually because it *has* to be
the module being compiled), change the reference to the variant
that omits that qualifier; otherwise, keep the qualifier.
In a few places, improve the wording of an error message.

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.

tests/hard_coded/boyer.m:
Fix something I missed.
Specifically, when we find undefined types in type definitions, say WHERE
the undefined type is (both as line number and as function symbol/arg number,
and field name if present), since the body of the type definition is sometimes
quite big.
compiler/module_qual.m:
When module qualification found an error, it used to get the context
it printed for the error from the mq_info structure, which also contained
the rest of the state of the qualification process. The drawback of this
setup is that the mq_info's record of the error context was updated
only in a few of the places where that context actually changed.
This diff takes the error context out of the mq_info, and passes it
as a separate argument to the predicates that need it. This makes it
really visible if a context is passed onward unchanged even when it
should be updated.
Fix some of these places, and mark the rest with XXXs.
When printing error messages about predicate or function declarations,
the message talked about definitions, not declarations. Fix that.
Put a prog_context inside each function symbol of mq_error_context;
don't require the creation of a separate memory cell for a pair
to link the mq_error_context with the prog_context.
Factor out some common code.

I tried to put a context inside constraints for use in error contexts
in module_qual.m, but that turned out to be a bad idea. Document why.

Do not display the `For more information try recompiling with `-E'' prompt
unless we really mean it, i.e. there is actually more information available.
XXX This change is incomplete for the mode_errors module because that
module requires more substantial changes to make this work - I'll do
that as a separate diff.

Add a new global (and access predicates) that keeps track of whether
we have any verbose error information that could be displayed if we
recompiled with `-E'.
