MDEV-452 Add full support for auto-initialized/updated timestamp and datetime
Generalized support for auto-updated and/or auto-initialized timestamp and datetime columns. This patch is a reimplementation of MySQL's "WL#5874: CURRENT_TIMESTAMP as DEFAULT for DATETIME columns". In order to ease future merges, this implementation reused few function and variable names from MySQL's patch, however the implementation is quite different. TODO: The only unresolved problem in this patch is the semantics of LOAD DATA for TIMESTAMP and DATETIME columns in the cases when there are missing or NULL columns. I couldn't fully comprehend the logic behind MySQL's behavior and its relationship with their own documentation, so I left the results to be more consistent with all other LOAD cases. The problematic test cases can be seen by running the test file function_defaults, and observing the test case differences. Those were left on purpose for discussion.
