Fixed the remaining join variations, (left, right, natural, etc).
(Previous fix only solved "," and "[cross] join".)
mysql-test/r/select.result:
Added more test case results for more braced join fixes.
mysql-test/t/select.test:
Added more tests for braced join fixes.
sql/sql_yacc.yy:
Changed the remaining join_table_list cases to handle braces.
Also added some precedence declaration to silence shift/reduce conflicts
warnings that turned up after these fixes.
WHERE column_name = key_column_name was calculated as true
for NULL values.

fix for multi-table updates
This is a simple fix, allowing a join_table_list in the right reduction of a
normal_join sequence, instead of just a join_table. This makes things like
"t1, (t2 left join t3)" work, but it also allows "join" and "cross join" instead
of ",".
This should fix the bug reported as:
Subject: ODBC SQL syntax issue
From: Ivan Vazharov
Date: Mon, 30 Sep 2002 12:02:42 +0200

first one.
