a8da2b6a99 ISO: remove nonstandard operator meta_predicate. 
Use functional notation instead for declarations.

This addresses #2822.

e9bb41f0d6 ENHANCED: use a fast test for the expected case of chars in atom_chars/2 etc. 
Suggested by Oleg Finkelstein, thank you a lot!

Example, before this change:

    ?- t+\(length(As, 1_000_000), maplist(=(a), As), time(atom_chars(A, As))).
       % CPU time: 0.693s, 7_000_041 inferences
       true.

Now:

    ?- t+\(length(As, 1_000_000), maplist(=(a), As), time(atom_chars(A, As))).
       % CPU time: 0.080s, 40 inferences
       true.

This also partially ameliorates #2907.

b76bdd75e4 Fix #2725 by calling load_context/1 in the unspecified branch of strip_module/3 
This fixes #2725, by making it so that `strip_module(Pred, M, P), call(M:P)`
doesn't throw an `instanciation_error` when `Pred` isn't in the form `module:predicate`.

Now, `strip_module(hello, M, P)` will call `load_context(M)`, which unifies `M`
with the topmost module (or `user`).

Two new test cases are added: issue2725.pl, which tests the minimal case id(X) --> X.
and the strip_module(P, M, _), call(M:P) scenario, and module_resolution,
which tests the behavior of strip_module in a few scenarios.

aca0de06cd FIXED: make occurs_check and answer_write_options flags discoverable 
Quoting from 7.11 Flags:

   NOTE - A built-in predicate current_prolog_flag(Flag, Value)
   (8.17.2) enables a program to discover all the flags supported
   by a processor and their current values.
