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

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.

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.

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:

88a2b82f7e ENHANCED: library(crypto): Retain the compact representation of strings. 
This avoids the costly (in terms of space requirements!) conversion of
compact lists of characters to lists of integers, making hashing, HKDF,
encryption, decryption, signing and signature verification an order of
magnitude more efficient (primarily in terms of space, also in time).

This makes library(crypto) suitable to process also very large files.
