* Provide backwards compatibility extension to name resolution of
coalesced columns. The patch allows such columns to be qualified
with a table (and db) name, as it is in 4.1.
Based on a patch from Monty.
* Adjusted tests accordingly to test both backwards compatible name
resolution of qualified columns, and ANSI-style resolution of
non-qualified columns.
For this, each affected test has two versions - one with qualified
columns, and one without.

sql/sql_base.cc:
* Applied Monty's patch for backwards compatible name resolution
of qualified columns. The idea is:
- When a column is qualified, search for the column in all
tables/views underlying each natural join. In this case
natural joins are *not* considered leaves.
- If a column is not qualified, then consider natural joins
as leaves, thus directly search the result columns of
natural joins.
* Simplified 'find_field_in_tables()' - unified two similar
loops into one.
sql/table.cc:
- Removed method & members not needed after Monty's patch.
sql/table.h:
- Removed method & members not needed after Monty's patch.
tests/mysql_client_test.c:
Put back old tests to test that coalesced columns of natural joins can be qualified.
