Mark Thom c7e1f5d568 Merge pull request #1630 from epilys/fix-1625 
fix type_error with instantiated EOF -1 byte literal in get_byte/2

Markus Triska d91ee5b77c FIXED: CLP(ℤ): Correctly remove all attributes during propagation of all_distinct/1 and other global constraints. 
The constraints from library(clpz) were already correctly removed, but
others such as pending freeze/2 goals were not, potentially leading to
an accumulation of redundant constraints during propagation.

Test case:

   ?- freeze(A,(X=1;X=2)), all_distinct([A]), A = 1.
      A = 1, X = 1
   ;  A = 1, X = 2.

The combination of freeze/2 and CLP(ℤ) is useful for example when
creating animations of search processes.

This addresses #1624.

Markus Triska b2cccab768 ENHANCED: library(crypto): Faster conversion to bytes when the integer is known. 
These entailed constraints only affect performance, and can be removed
without affecting the correctness of the code. They speed up scalar
multiplication of a curve point, used for example in Bitcoinolog.

Examples:

    ?- chars_si("hello").
       true.

    ?- chars_si(5).
       false.

    ?- chars_si([a,b,c|Rs]).

Markus Triska 7c5318b784 ENHANCED: Use '$skip_max_list'/4 for greater efficiency of nth0/3. 
This is now possible due to 4c7e2eb8614da9c04f2286f6116b468017fb442c.

See #1529 for the suggestion by @UWN.

Markus Triska c7caf6b7a9 ENHANCED: CLP(ℤ): Reduce redundant propagator invocations during all_distinct/1 filtering 
First, the current propagator is now logged and not re-triggered
during filtering. Second, and more significantly, all neq_num/2
constraints are scheduled and processed before more global constraints
are invoked. In this way, all the distilled information can be taken
into account by subsequently invoked global constraints.

These changes yield a 3-fold improvement in several Sudoku instances,
and a significant runtime reduction in social golfer instance 8-4-9.
