Malcolm Tredinnick ba015e0a79 Fixed #7181 -- when ordering by a potentially NULL field, use a left-outer join
so that the ordering doesn't accidentally restrict the result set.

(Ironically, one existing test actually showed this problem, but I was too
dumb to notice the result was incorrect.)

Malcolm Tredinnick 588eeb356c Fixed a problem when constructing complex select_related() calls.
Avoids joining with the wrong tables when connecting select_related() tables to
the main query. This also leads to slightly more efficient (meaning less tables
are joined) SQL queries in some other cases, too. Some unnecessary tables are
now trimmed that were not previously.

Malcolm Tredinnick 1834428648 Fixed a problem with values() and values_list() queries and nullable joins.
Previously, if we were querying across a nullable join and then a non-nullable
one, the second join would not be a LEFT OUTER join, which would exclude
certain valid results from the result set.

This is the same problem as [7597] but for values() field specifications, so
this covers the second case where Django adds extra stuff to the select-clause.

Jacob Kaplan-Moss 31d9dc07aa Fixed #7369: fixed a corner-case involving select_related() following non-null FKs after null ones. Thanks, George Vilches

Adrian Holovaty 14d6ee2dc9 Changed Query.get_columns() to quote the 'AS' column names in an extra_select situation, to match pre-queryset-refactor behavior. Added unit tests that verify this and provide an example

Malcolm Tredinnick e07a457c00 Fixed #7096 -- The simplifications in [7461] weren't complete. They broke
multi-component exclude() calls. Fixed that.
