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:
Splits out the SQL changes. These are most of the changes, but primarily mechanical:
- Moved "initialize.sql" to "0000.legacy.sql" and partially reverted to an older version, such that patches 0000 + 000 + 001 + ... + 137 put us in the right state when applied sequentially.
- Removed "create database" commands from all SQL. These are handled by separate DB patches now, so we have the data to do operations like "storage databases" (list databases) and "storage destroy" (drop databases).
- Removed "phabricator_" namespace from all SQL, and replaced with "{$NAMESPACE}_" token so we can namespace databases.
- Shortened some column lengths so patches apply correctly if originally created as InnoDB; also a few similar tweaks elsewhere.
Test Plan: See D2323 for discussion and test plan.
