* Mysql.new, Mysql.conncet and Mysql#connect takes URI object or URI string

  Mysql.connect('mysql://user:password@hostname:port/dbname?charset=ascii')
  \ 
Mysql.connect('mysql://user:password@%2Ftmp%2Fmysql.sock/dbname?charset=ascii') \ 
# for UNIX socket
  Mysql.connect('hostname', 'user', 'password', 'dbname')
  Mysql.connect(host: 'hostname', username: 'user', password: 'password', \ 
database: 'dbname')

* Mysql.options is removed. use Mysql#param = value instead. For example:

	m = Mysql.init m.options(Mysql::OPT_LOCAL_INFILE, true)
	m.connect(host, user, passwd)

  change to

	m = Mysql.new m.local_infile = true
	m.connect(host, user, passwd)

  or

	m = Mysql.connect(host, user, passwd, local_infile: true)

* Mysql::Time is removed. Instead, Time object is returned for the DATE,
  DATETIME, TIMESTAMP data, and Integer object is returned for the TIME
  data.  If DATE, DATETIME, TIMESTAMP are invalid values for Time, nil is
