Problem: lack of out-of-bound memory checks in tests

Solution: add a CI build run with GCC's Address Sanitizer enabled.
This compiler flag will make the unit test programs abort if it
detects errors such as out-of-bound memory access or use-after-free.

Problem: insufficient error handling relative to zap_connect.

Problem: assert used for ZAP error handling aborts process.

Problem: No relicense file for jemc contributions.

Solution: Add relicense file.
