[CBRD-24835] Added reading the schema information of the target object that created the synonym

[airnet73]

http://jira.cubrid.org/browse/CBRD-24835

Purpose
Synonyms were added in cubrid 11.2. However, there is no way to read synonym schema information through cci api.
As a way to read synonym information is needed, a way to read schema information of the user who created the synonym using cci_schema_info() is needed.

If the user name and synonym name are entered in cci_schema_info(), the schema information of the target object must be read when the synonym is created.

In this issue, only the function to read the column information of the target object corresponding to the synonym was added.

Implementation
To read the column information of the target object in the synonym, the type below must be used.
Type : CCI_SCH_ATTR_WITH_SYNONYM

If CCI_SCH_ATTR_WITH_SYNONYMand [schema].[synonym] are used for the type and class_name parameters of the cci_schema_info() function, column information of the synonym target object is returned.

cci_schema_info(conn, CCI_SCH_ATTR_WITH_SYNONYM, "u1.s1", NULL, CCI_ATTR_NAME_PATTERN_MATCH, &error);

Remarks
N/A
