Summary:
The main PHP code churn is caused by extracting the common code from `FacebookArcanistConfiguration.php` and `FacebookOldArcanistConfiguration.php` into `RocksDBCommonDeterminator.php`. This is necessary both for reducing the duplication of code and making sure that we can execute the common core logic separately from continuous runs.
The main logic in `RocksDBCommonDeterminator.php` remains quite the same with the exception of some things:
- Adding separation between the cases when a diff is submitted //vs.// when the code is triggered from a continuous run. There are certain actions which we should do in a case of diff only.
- Adding reporting - now the person who authored the diff will receive e-mail notifications if any of the jobs have failed.
- Enabling assertions and making sure that we'll terminate on failure. This is an internal code used by competent engineers, so instead of `if (!condition) { echo "Something"; exit(1); }` for every invariant I think that `assert(condition)` provides better readability with the same behavior. Especially taking into account that we're talking about things which shouldn't ever happen.
Enabling this entire process will be triggered internally and will be a subject of a separate code review. We should discuss the details of triggering continuous RocksDB build and tests on that diff.
Test Plan:
- Make sure that `[p]arc diff` scenario isn't broken by verifying that tests validating this diff will pass.
- Private testing of triggering the continuous build script.
- Once the changes will land then author an internal job which will use the script and verify its validity.

Summary:
Right now the way we do BlockIter::Prev() is like this
- Go to the beginning of the restart interval
- Keep moving forward (and decoding keys using ParseNextKey()) until we reach the desired key
This can be optimized by caching the decoded entries in the first pass and reusing them in consecutive BlockIter::Prev() calls
Before caching

Summary:
Two changes here:
- Remove dead Jenkins related code which is no longer relevant.
- Support `arc diff --preview`. Currently it doesn't work because a step which applies a diff assumes that a revision has been created. Which in case of `--preview` isn't. Therefore diff can't be applied and validation fails. Solution is to use `--nocommit` because for validation purposes performing a commit isn't necessary.
Test Plan:
- Current changes are submitted using `arc diff --preview`.
- All the pre-commit verification tests passed.

If wal_recovery_mode = kPointInTimeRecovery, do not halt immediately after encounter corruption. Instead, check if seq id of next log file is last_log_sequence + 1. In that case we continue recovery.
