This reverts commit 46333dbf6211ea197965c30fdbecbeb62bc81e5b. Reason for revert: Downstream test broken by changed error message. Original change's description: > Wire up proto-free event log format in encoder and parser. > > Encode ALR state events as an example. The ALR state unit tests pass with the new format, but the tests are not enabled in this CL since the other event types aren't encoded yet. > > Bug: webrtc:11933 > Change-Id: I3ba22778b55f24e2e2bd7d95bb9b17de29ef899f > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/234520 > Reviewed-by: Sebastian Jansson <srte@webrtc.org> > Commit-Queue: Björn Terelius <terelius@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#35752} TBR=terelius@webrtc.org,srte@webrtc.org,webrtc-scoped@luci-project-accounts.iam.gserviceaccount.com Change-Id: I9a21ec3c4f876102da146898b840c740f575e03c No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: webrtc:11933 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/247901 Reviewed-by: Björn Terelius <terelius@webrtc.org> Reviewed-by: Sebastian Jansson <srte@webrtc.org> Commit-Queue: Björn Terelius <terelius@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35753}
