Summary:
pushrebase_errmsg is NULL when we have conflicts, but we still shouldn't replay
the entry (because it'll fail, with conflicts). Let's exclude those.

Summary:
This adds a unbundle_replay Rust binary. Conceptually, this is similar to the
old unbundle replay Python script we used to have, but there are a few
important differences:
- It runs fully in-process, as opposed to pushing to a Mononoke host.
- It will validate that the pushrebase being produced is consistent with what
is expected before moving the bookmark.
- It can find sources to replay from the bookmarks update log (which is
convenient for testing).
Basically, this is to writes and to the old unbundle replay mechanism what
Fastreplay is to reads and to the traffic replay script.
There is still a bit of work to do here, notably:
- Make it possible to run this in a loop to ingest updates iteratively.
- Run hooks.
- Log to Scuba!
- Add the necessary hooks (notably globalrevs)
- Set up pushrebase flags.
I would also like to see if we can disable the presence cache here, which would
let us also use this as a framework for benchmarking work on push performance,
if / when we need that.
