Remove support for the mysql adapter in the Gemfile (Feature #1029)

For Ruby 1.8, we currently support the mysql and mysql2 adapter. This is rather confusing for people and doesn't really help anyone. mysql2 is more stable, faster and maintained (which mysql is not). I thus propose to:

  • remove the mysql adapter
  • retain the mysql group but include the mysql2 adapter in it
  • deprecate the mysql2 group

Maybe, for 4.0 we can completely remove the mysql2 group (and the mysql adapter). We then just need to adapt the upgrade guide.

Works for me, the deprecation of the mysql2 group should be well documented though. Couldn't we just leave it as an alias to the mysql group?

After discussion in IRC, we target this for 4.0 where we will completely switch to the mysql2 adapter
