Construct a copy of this object to be used for mysql_alter_table
1270
and mysql_create_table.
1272
Historically, these two functions modify their Alter_info
1273
arguments. This behaviour breaks re-execution of prepared
1274
statements and stored procedures and is compensated by always
1275
supplying a copy of Alter_info to these functions.
1277
@return You need to use check the error in Session for out
1278
of memory condition after calling this function.

Make deep copies of used objects.
1295
This is not a fully deep copy - clone() implementations
1296
of Alter_drop, Alter_column, Key, foreign_key, Key_part_spec
1297
do not copy string constants. At the same length the only
1298
reason we make a copy currently is that ALTER/CREATE TABLE
1299
code changes input Alter_info definitions, but string
1300
constants never change.
