Ref T7789. This builds on top of `git-lfs-authenticate` to detect LFS requests, read LFS tokens, and route them to a handler which can do useful things.
This handler promptly drops them on the floor with an error message.
Test Plan:
Here's a transcript showing the parts working together so far:
- `git-lfs` connects to the server with SSH, and gets told how to connect with HTTP to do uploads.
- `git-lfs` uses HTTP, and authenticates with the tokens properly.
- But the server tells it to go away, and that it doesn't support anything, so the operation ultimately fails.

For most field values this is cheap, but for some (like a commit's branches) it can be quite expensive. We only want to pay this cost once, so we cache field values.
However, D12957 accidentally added a check where we bypass the cache and generate the value for every field, before reading the cache. This causes us to generate each field for every rule that uses it, plus one extra time.
Instead, use the cache for this check, too. Also allow the cache to cache `null`, since it can be expensive to generate `null` even though the value isn't too interesting.
The value of this early hit isn't even used (we only care if it throws or not).
Test Plan:
- Wrote a rule like "if any condition matches: branches contain a, branches contain b, branches contain c".
- Put `phlog(new Exception())` in `DiffusionCommitBranchesHeraldField`.
- Before patch, saw `bin/repository reparse --herald <any commit>` compute branches three times.

GitHub has a second, similar activity stream which does report these events (the "Issues Events API").
Use two separate cursors: one consumes the primary stream; the second consumes the events stream.
One possible issue with this is that we may write events in a different order than they occurred, so GitHub shows "comment, label, close" but we show "comment, close, label" or similar. This is probably OK because the secondary API doesn't seem to have any very important events (e.g., it's probably fine if label changes are out-of-order), but we can conceivably put some buffer stage in between the two if it's an issue.
