1fa8a0a969 ENHANCED: more memory efficient call_nth/2 (#1264) 
I hope that this will allow more extensive tests of Scryer Prolog. Enjoy!

MODIFIED: Rename two predicates in library(charsio)

516ed1fd5b ENHANCED: library(crypto): Retain a compact internal representation of the ciphertext throughout decryption. 
This allows efficient decryption also of very large files and long
strings.

It is usually highly advisable to stick to common and portable library
predicates such as append/3. However, since append/3 does not yet
recognize this opportunity for improvement, I apply it manually in
this case, so that also very large files can be efficiently decrypted
using the compact internal string representation.

Without this change, decrypting a 1 GB file takes 48 GB of RAM,
whereas with this change, it only takes 2 GB (one for the string, one
for its copy with the appended tag).

23adfef281 MODIFIED: library(charsio): read_n_chars/3 is now called get_n_chars/3 
This is because "read" is associated with general Prolog terms.

Markus Triska
20b6816562 MODIFIED: library(charsio): read_term_from_chars/2 is now called read_from_chars/2 
This is for compatibility with SICStus Prolog and GNU Prolog.
