2014-05-05gib_list_randomize: use code better suited for short lists (closes #151)Daniel Friesel-6/+4
Note that the i == r check was never reached in the original code but may be in the new variant. Since a shuffled list may well have one or two elements retain their absolute position once in a while, this should not be a problem. tests with 2- and 3-element lists show an even distribution amongst all elements.
2014-05-04strip unneded parts from giblib, part 1Daniel Friesel-2/+10
Not all functions were examined yet. Also TODO: * check strdup / malloc calls (some are apparently unchecked in giblib), maybe use estrdup / emalloc for those * Check includes and update dependency list if needed
