Patch to fix issues related to parsing transport URLs.
- Added unit tests for create_transport and
  fixed problems discovered.
- Rewrote create_transport:
  - Removed restriction to 20 characters file name.
  - Removed unnecessary dynamic memory allocation
  - Added default 3306 for port
- Fixed TCP URL parsing:
  - Empty user or hostname was accepted, which
    should not be accepted.
- Fixed file URL parsing:
  - Disallowed user and host instead of treating
    them as part of the file name.
  - File URLs according to spec accept host part,
    but we do not accept that currently.
- Binlog_file_driver::get_position() did not return
  file name correctly.
- Binlog_tcp_driver constructor initialized members
  twice. Moved initialization to initializer list.
