Summary:
Ref T1191. When changing the column type of an AUTO_INCREMENT column, we currently may lose the autoincrement attribute.
Instead, support it. This is a bit messy because AUTO_INCREMENT columns interact with PRIMARY KEY columns (tables may only have one AUTO_INCREMENT column, and it must be a primary key). We need to migrate in more phases to avoid this issue.
Introduce new `auto` and `auto64` types to represent autoincrement IDs.
Test Plan:
- Saw autoincrement show up correctly in web UI.
- Fixed an autoincrement issue on the XHProf storage table with `bin/storage adjust` safely.

Summary:
Ref T1191. This was useful for annotating everything but we no longer need it; there are just two types of issues now:
- Error: stuff we can't fix (missing or surplus tables/database/columns, bad column nullability).
- Warning: stuff we can fix (column types, character sets, collations, missing or surplus keys, incorrectly defined keys, bad key uniqueness).
Test Plan: Saw 3,399 warnings and 0 errors.

Summary:
Ref T1191. Ref T6203. While generating expected schemata, I ran into these columns which seem to have sketchy nullability.
- Mark most of them for later resolution (T6203). They work fine today and don't need to block T1191. Changing them can break the application, so we can't autofix them.
- Forgive a couple of them that are sort-of reasonable or going to get wiped out.
Test Plan: Saw 94 remaining warnings.

Summary:
Ref T1191. We have several keys on `<x, y, id>`. When `id` is an auto-increment primary key, I believe this is exactly equivalent to a key on `<x, y>`, because the leaf nodes are implicitly sorted by `id`. We omit the implicit `id` elsewhere.
It would be nice to drop the `id` bit for consistency, but it's not doing any harm and this doesn't need to block the primary work of T1191.
Test Plan: Saw slightly fewer warnings.

Summary:
Ref T1191.
- Adds definitions for missing keys and keys with wrong uniqueness. Generally, I defined these before fixing the key query to actually pull all keys and support uniqueness.
- Moves "key uniqueness" to note severity; this is fixable (probably?) and there are no remaining issues.
- Moves "Missing Key" to note severity; missing keys are fixable and all remaining missing keys are really missing (either missing edge keys, or missing PHID keys):
{F210089}
- Moves "Surplus Key" to note seveirty; surplus keys are fixable all remaining surplus keys are really surplus (duplicate key in Harbormaster, key on unused column in Worker):
{F210090}
Test Plan:
- Vetted missing/surplus/unique messages.
- 146 issues remaining.

Summary:
Ref T1191. Some notes here:
- Drops the old LDAP and OAuth info tables. These were migrated to the ExternalAccount table a very long time ago.
- Separates surplus/missing keys from other types of surplus/missing things. In the long run, my plan is to have only two notice levels:
- Error: something we can't fix (missing database, table, or column; overlong key).
- Warning: something we can fix (surplus anything, missing key, bad column type, bad key columns, bad uniqueness, bad collation or charset).
- For now, retaining three levels is helpful in generating all the expected scheamta.
Test Plan:
- Saw ~200 issues resolve, leaving ~1,300.
- Grepped for removed tables.

Summary:
Ref T1191. Three parts:
- The old way of getting key information only got primary / unique / foreign keys, not all keys. Use `SHOW INDEXES` to get all keys instead.
- Track key uniqueness and raise warnings about it.
- Add a new "all issues" view to show an expanded, flat view of all issues. This is just an easier way to get a list so you don't have to dig around in the hierarchical view.

Ref T1191. Notable:
- Allowed objects to remove default columns (some feed tables have no `id`).
- Added a "note" severity and moved all the charset stuff down to that to make progress more clear.

Summary:
Ref T1191. The major issue motivation here is that InnoDB keys have a maximum length of 767 bytes. When we move `utf8` colums to `utf8mb4` columns, they'll jump from 3 bytes per character to 4 bytes per character, which may make some indexes too long. Add key schema to help spot this.
Also add nullability since it doesn't hurt.
Test Plan: See screenshots.

Summary:
Ref T1191. This builds on the "view of the database as it exists" by building a view of the database as it is expected to exist (this is mostly empty for now) and comparing the two. We now render a view of the "comparison schema", which is the actual schema merged with the expected schema and annotated with the differences.
(I'm merging them like this because it makes it easier to handle both "missing" and "surpulus" warnings in a consistent way. If we tried to annotate just the actual or expected schema, the absence of components which are expected to exist is messy to handle.)
Test Plan: See screenshots.
