Summary:
Ref T4045. Ref T5179. While we'll eventually need to force a migration, we can let installs (particularly large installs) do an online migration for now. This moves hunks to the new storage format one at a time.
(Note that nothing writes to the new store yet, so this is the only way to populate it.)
WARNING: Installs, don't run this yet! It won't compress the data. Wait until it can also do compression.
Test Plan: Added a `break;` after migrating one row and moved a few rows over. Spot checked them in the database and viewed the affected diffs.

Summary:
Ref T4045. Ref T5179. Hunk storage has two major issues:
- It's utf8, but actual diffs are binary.
- It's huge and can't be compressed or archived.
This introduces a second datastore which solves these problems: by recording hunk encoding, supporting compression, and supporting alternate storage. There's no actual compression or storage support yet, but there's space in the table for them.
Since nothing actually uses hunk IDs, it's fine to have these tables exist at the same time and use the same IDs. We can migrate data between the tables gradually without requiring downtime or disrupting installs.
Test Plan:
- There are no writes to the new table yet.
- The only effect this has is making us issue one extra query when looking for hunks.
- Observed the query issue, but everything else continue working fine.
- Created a new diff.
- Ran unit tests.

Summary:
Ref T4045. We have a lot of direct queries against the hunk table right now. These are messy, not really policy-aware, and limit our options on T4045.
This query is unusual (it requires changesets, and does not accept IDs). This keeps us from having to load changeset -> diff -> revision in order to do policy checks. We could also fix this with smarter policy checks and caching, but I'd rather not open that can of worms for now. This object is very low level and relatively unusual, and this small deviation from convention seems like the cleanest cut to make to keep this from snowballing.
Test Plan: Used Herald dry runs to verify that the affected rules still output the same data.

Summary: Ref T4045. These three methods are fairly copy-pastey. Provide a more formal DifferentialHunk API for querying various types of line ranges.
Test Plan: Used test console to verify that "added content", "removed content", and "changed content" rules still produce the same data.

Summary:
Does what it says on the label. We already had 'Any changed file content', now we have 'Any added file content' and 'Any removed file content'.
- There is a bit of copied/pasted code here: I'm open to suggestions on how to refactor it so it's less redundant.
- The wording seems a little awkward, and as @epriestley mentioned in T3829, moved code will be detected less than ideally.
Test Plan: Created Herald Rules, verified via dry run that they were triggered in appropriate situations.

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

Summary: I will also need `getRemovedLines()` so refactor this first.
Test Plan:
New test case.

Verified that the only callsite of `getAddedLines()` trims lines.

- `kill_init.php` said "Moving 1000 files" - I hope that this is not some limit in `FileFinder`.

- Comment `phutil_libraries` in `.arcconfig` and run `arc liberate`.
