7cf4f2eb89 Preliminary MySQL support. Barely tested.
Requirements:
MySQL/MariaDB need to be configured with this settings:

  innodb_file_format = Barracuda
  innodb_file_per_table = On
  innodb_large_prefix = On

to support key prefix length up to 3042 bytes.

MySQL/MariaDB DSN will need this parameter:

  parseTime=true

as per [1]

The migration system itself mostly inspired by Rails (ActiveRecord),
but it still rough at the edges. Could use some inputs.

Next Todo: more testing!

51519b62dd Actually use --driver option to set database driver for drone.
This includes refactoring database setup, and migration system.

Remove setupDatabase from main and use `Init` method from database
package.

At database package, defines Init method which actually initiate
database with options given from comand line flag. I think `--path`
wont be used anywhere so I plan to remove it later.

Both meddler and migration initiated here, then we call `Set` method
to setup all the tables, etc. Here I think I want to separate database
schema and turn it into migration script instead, later maybe.

At migration package I made some tweak to `Operation` interface.
Realized that it's ludicrous to let migration driver re-implement `Exec`
and `Query`, I made migration script to receive The whole
migrationDriver struct which contains both Operation implementor, and
the Tx itself. This made possible thanks to Go struct being able to
promote its member, now our migration is more transparent.

There's also stub implementation for bot mysql and postgresql, will
implement this really soon.

8ce87f0d2c More tests for alter columns migration
Also change the way we handle columns rename migration.
SQLite restrict column addition not to have PRIMARY KEY and/or
UNIQUE attribute, so we have to change from:

add new column -> migrate data from old column to new column ->
rename old table -> create new table with old columns removed ->
migrate data from old table to the new table -> drop old table

to directly:
rename old table -> create new table with renamed columns ->
migrate data from old table to the new table -> drop old table
