Summary:
Ref T1191. Notable stuff:
- Adds `--disable-utf8mb4` to `bin/storage` to make it easier to test what things will (approximately) do on old MySQL. This isn't 100% perfect but should catch all the major stuff. It basically makes us pretend the server is an old server.
- Require utf8mb4 to dump a quickstart.
- Fix some issues with quickstart generation, notably special casing the FULLTEXT handling.
- Add an `--unsafe` flag to `bin/storage adjust` to let it truncate data to fix schemata.
- Fix some old patches which don't work if the default table charset is utf8mb4.
Test Plan:
- Dumped a quickstart.
- Loaded the quickstart with utf8mb4.
- Loaded the quickstart with `--disable-utf8mb4` (verified that we get binary columns, etc).
- Adjusted schema with `--disable-utf8mb4` (got a long adjustment with binary columns, some truncation stuff with weird edge case test data).
- Adjusted schema with `--disable-utf8mb4 --unsafe` (got truncations and clean adjust).
- Adjusted schema back without `--disable-utf8mb4` (got a long adjustment with utf8mb4 columns, some invalid data on truncated utf8).
- Adjusted schema without `--disable-utf8mb4`, but with `--unsafe` (got truncations on the invalid data).

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. Currently, the `quickstart.sql` gets generated in a pretty manual fashion. This is a pain, and will become more of a pain in the world of utf8mb4.
Provide a workflow which does upgrade + adjust + dump + destroy, then massages the output to produce a workable `quickstart.sql`.
Test Plan: Inspected output; I'll test this more throughly before actually generating a new quickstart, but that's some ways away.

Summary:
Ref T1191. For most text columns, we either don't care if "a" and "A" are the same, or we expect them to be different (for example: keys, domains, secrets, etc). Default text columns to the `_bin` collation so they are compared by strict character value. This is safer in cases where we aren't sure.
For some text columns, we allow the user to sort by the column in the UI (like Maniphest task titles) or we do care that "A" and "a" are the same (for example: project names). Introduce a new class of virtual data types, the "sort..." types, to cover these columns. These are like the "text..." types but use sorting collations which treat "A" and "a" the same.
Test Plan:
- Made an effort to identify all columns where the UI relies on database collation.
- Ran `bin/storage adjust` and cleared all warnings.

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.
- Adds support for custom fields.
- Adds support for partial indexes (indexes on a prefix of a column).
- Drops old auxiliary storage table: this was moved to custom field storage about a year ago.
- Drops old project table: this was moved to edges about two months ago.
Test Plan:
- Viewed web UI, saw fewer issues.
- Used `grep` to verify no readers/writers for storage or project table.

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.

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 lays some groundwork for generating the expected schemata, so we can compare them to the actual schemata and produce a meaningful diff.
- In general, each application will subclass `PhabricatorConfigSchemaSpec` and provide a definition of the tables it expects.
- This class has helper methods to mostly-automatically build table definitions for Lisk and (in the future) edges.
- When building expected schema, we specify a "data type", like "epoch". This is the type of data the application stores in the column, from the application's point of view. The SchemaSpec converts this into the best avilable storage type: for example, "text" will translate to `utf8mb4` if it's availalbe, or `binary` if not. This gives us a layer of indirection to insulate us from craziness.
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.

Summary:
Ref T1191. Plan here is:
- Build a tool showing the current schemata status (this diff).
- Have it compare the current status to the desired status (partly here, mostly in future diffs).
- Then add a migration tool, and eventually a setup issue to tell people to run it.
Test Plan:
Reviewed current schemata.
