45d1b20639 Fix the sqlite3_table_column_metadata() routine so that it gives the correct 
answer for the "rowid" column in a WITHOUT ROWID table.  Enhance it so that
it can be used to check for the existence of a table by setting the column
name parameter to NULL.  The routine is now included in the build by
default, even without the SQLITE_ENABLE_COLUMN_METADATA compile-time option.

8c3026ecf3 Make the sqlite3_table_column_metadata() interface available by default and 
without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option.
Other sqlite3_column_* interfaces that have a run-time penalty even if they
are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at
compile-time.
