With ibmdb2i_create_index_option set to 1, creating an IBMDB2I table
with a primary key should produce an additional index that uses EBCDIC
hexadecimal sorting. However, this does not work. Adding indexes that
are not primary keys does work. The ibmdb2i_create_index_option should
be honoured when creating a table with a primary key.
This patch adds code to the create() function to check for the value
of the ibmdb2i_create_index_option variable and, when appropriate, to
generate a *HEX-based shadow index in DB2 for the primary key. Previously
this behavior was limited to secondary indexes.
Additionally, this patch restricts the creation of shadow indexes to
cases in which a non-*HEX sort sequence is used, as the documentation
for ibmdb2i_create_index_option describes. Previously, the shadow index
would in some cases be created even when the MySQL-specific index used
*HEX sorting, leading to redundant indexes.
Finally, the code used to generate the list of fields for indexes
and the code used to generate the SQL statement for the shadow
indexes has been refactored into individual functions.

when creating a table with a primary key.

Bug#45983 ibmdb2i_create_index_option=1 not working for primary key
- Add code to the create() function to check for the value of the
ibmdb2i_create_index_option variable and, when appropriate, to
generate a *HEX-based shadow index in DB2 for the primary key.
- Restrict the creation of shadow indexes to cases in which a
non-*HEX sort sequence is used.
- Refractor code used to generate the list of fields for indexes
and the code used to generate the SQL statement for the shadow
indexes into individual functions.

Bug#45983 ibmdb2i_create_index_option=1 not working for primary key
Add function prototypes for the functions that.
- Generate the list of fields for indexes
- Generate the SQL statement for the shadow
indexes
