api: enable binary API event logging in vat
Cleaned up a few instances of side-bet elog_string hash table
usage. Elog_string handles that problem itself.
Add cli commands to vat to initialize, enable/disable, and save an
event log.
Event logging at the same time in both vpp and vat yields a pair
of event logs which can be merged by the "test_elog" tool.
Type: refactor
