When the GROUP BY clause contains a column reference that can be resolved to
both an aliased column in the SELECT list, and to a column in the FROM clause,
the group column is resolved to the column in the FROM clause (for ANSI conformance).
However, it may be so that the user's intent is just the other way around, and he/she
gets the query results grouped by a completely different column than expexted.
This patch adds a warning in such cases that tells the user that there is potential
ambiguity in the group column.

sql/sql_select.cc
- Added a warning when a GROUP column is ambiguous due to that there is a
  column reference with the same name both in the SELECT and FROM clauses.
  In this case we resolve to the column in FROM clause and warn the user
  of a possible ambiguity.
- More extensive comments.
- Changed the function to return bool instead of int (as in other places).

The problem was that when there was no MIN or MAX function, after finding the
group prefix based on the DISTINCT or GROUP BY attributes we did not search further
for a key in the group that satisfies the equi-join conditions on attributes that
follow the group attributes. Thus we ended up with the wrong rows, and subsequent
calls to select_cond->val_int() in evaluate_join_record() were filtering those
rows. Hence - the query result set was empty.

The problem occured both for GROUP BY queries without MIN/MAX and for queries
with DISTINCT (which were internally executed as GROUP BY queries).


mysql-test/r/group_min_max.result:
  Added test result for BUG#11044. Notice that the group by query is
  equivalent to the distinct query and both are executed via the same
  algorithm.
mysql-test/t/group_min_max.test:
  Added test for BUG#11044. Notice that the group by query is
  equivalent to the distinct query and both are executed via the
  same algorithm.
sql/opt_range.cc:
  * Use the extended prefix in QUICK_GROUP_MIN_MAX_SELECT::get_next()
    to find keys that satisfy equality conditions in the case when there is
    no MIN or MAX function.
  * Corrected some method comments.
  * Corrected debug printout of cost information.
