Markus Triska 4efbc20a4f ENHANCED: format_//2, format/[2,3], portray_clause/1 are now deterministic. 
This works as soon as #732 is merged, since then maplist/N and foldl/N
are deterministic in the required cases.

This also resolves the extra choicepoint of time/1 (see #378).

Many thanks to @notoria for implementing better indexing in #732,
which allowed me to find this opportunity for improvement!

Markus Triska 41a751e7f5 ADDED: Provisional support for (#=)/3 and (#<)/3. 
These predicates are intended for constructs from library(reif), such
as if_/3. For the time being, they are defined here. If you have any
recommendations or comments regarding the best location of these
predicates, or need more of them, please file an issue.

Suggested by @Qqwy in https://github.com/triska/clpz/issues/12.

Many thanks!

Markus Triska 46dfaa5b28 ENHANCED: library(files): Error handling if requested files do not exist. 
We now throw exceptions instead of failing silently, or even crashing
when using file_size/2 etc. with nonexistent files.

Markus Triska 5f3ab823fd FIXED: format_//2: Keep different variables distinct. 
Example:

        ?- phrase(format_("~w~w", [_,_]), Ls).
        %@    Ls = "AB"
        %@ ;  false.

Markus Triska 79cb4cd6a5 ADDED: First version of call_nth/2. 
A thread-safe implementation is possible for example with
'$nb_setarg'/3 (see #390).

Markus Triska e185b626bd FIXED: CLP(B): Delay BDD restriction until after the instantiation. 
This is necessary to actually take the new value into account.

Example:

    ?- sat(A*B>=C*D), A=1,B=0,C=1,D=1.
    false.

This addresses #670.

Markus Triska ad8e2ad4f6 omit internal attributes in residual goals when using taut/2 
Examples:

    ?- taut(X=:=X,1).
       clpb:sat(X=:=X)
    ;  false.

    ?- taut(X=\=X,0).
       clpb:sat(X=:=X)
    ;  false.

Markus Triska dcc4b91b35 ENHANCED: flush output for impure I/O (format/[2,3], portray_clause/1 etc.) 
Without this, we do not get a (timely) prompt in cases like:

    ?- format("press a key: ", []), get_single_char(C).

whereas for example write/1 already works in such cases:

    ?- write('press a key: '), get_single_char(C).
    press a key:
