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 Change-Id: I8d6a72206f2309c967ea1630077fba31aef47f93 Signed-off-by: Dave Barach <dave@barachs.net>
