commit 568dc27a1943305f6e11a9a497f56a6aabe27c99 Author: nikkolasg nikkolasg@gmail.com Date: Fri Jun 17 10:41:45 2016 -0400
Make base16_decodes return number of decoded bytes
base16_decodes() now returns the number of decoded bytes. It's interface changes from returning a "int" to a "ssize_t". Every callsite now checks the returned value.
Fixes #14013
