1.0 porting guide lists non-existant database backend functions

[nicklane]

See: ​http://docs.djangoproject.com/en/dev/releases/1.0-porting-guide/#database-backend-functions-have-been-renamed

Some of these have been removed (e.g. in r8296).

This ticket will need a proper patch, just noting these down here until I have a chance to put one together. I'm not that familiar with the code here, nor have I thoroughly investigated the code for each of these items so anyone feel free to correct me.

``backend.get_limit_offset_sql``         ``connection.ops.limit_offset_sql`` (removed?)

``backend.get_tablespace_sql``           ``connection.ops.sql_for_tablespace``
``backend.get_query_set_class``          ``connection.ops.query_class``

``backend.OPERATOR_MAPPING``             ``connection.operators`` (removed?)

``backend.allows_group_by_ordinal``      ``connection.features.allows_group_by_ordinal`` (removed)
``backend.allows_unique_and_pk``         ``connection.features.allows_unique_and_pk`` (removed)

``backend.needs_upper_for_iops``         ``connection.features.needs_upper_for_iops`` (removed)

It seems like this should be marked wontfix since not many people are migrating from 0.96 to 1.x any more and there seems to be no patch forthcoming. Feel free to undo the wontfix if there's a patch to be attached or if somebody feels like this is still important.
