The most critical bug is in nch5s3comms.c. I for some reason assumed that signing keys did not contain any zero bytes. But obviously it can, so a test was removed. Other fixes: 1. Guarantee allocated memory is initialized to all zeros. 2. Cleanup errmsg handling in libncpoco. 3. Fix processing of aws list-objects-v2 because I misread the syntax.
