1.3.0

CHANGES:

• The mariadb_config and mysql_config scripts are now used, if
  available, to discover MariaDB client library (#65 by Albert Peschar).
• Added server-side properties get_server_info, get_server_version,
  get_host_info and get_proto_info (#62 by Petter A. Urkedal).
• Avoid calling mysql_stmt_free_result if there is no result set, since
  this is not allowed by recent versions of the client library (by Petter
  A. Urkedal, fixes #64).
• Avoid possibly blocking calls to mysql_free_result in the nonblocking
  implementation. This was only an issue if a previous result set had not
  been consumed (#68 by Petter A. Urkedal, fixes #67).
• Fix memory leak in non-blocking test suite (Petter A. Urkedal, fixes
  #29).
