Migrate Python bindings to oursql module

[Raymond Wagner]

The current module used by the bindings for MySQL access is not supported by Python 2.7. 2.7 was only release in July, so it will take some time for distros to push this out to their stable packages, but this will likely become an issue at some point before the 0.25 release. If necessary, this may be backported to 0.24.

Oursql is not readily available in package repositories, so this will have an intermediate layer allowing fallback to the old module if on 2.6.

MythArchive will be similarly affected, and should be altered to access the database through the bindings.

Initial commit at r27184. Support added, but currently disabled pending ​https://bugs.launchpad.net/oursql/+bug/672059 . The 'ENABLE_OURSQL' environmental variable must be set to 'true' to enable it.

(In [27327]) Fix mirobridge to pass storagegroup directory name through unchanged if it is already unicode. Closes #9279 for now. Refs #8768. If this is going to be a recurring issue, it may be better to for all strings outputted by the MySQLdb module to unicode as well for consistency, and deal with whatever code needs to be fixed as a result.

Closing this one as fixed. The ENABLE_OURSQL flag is still required, and will be removed once the next version is released, incorporating the fix described above.
