Splitting Packages

The package specification is migrated as a schema named after the package and the procedures and functions in the package body is migrated as Packagename.procedurename and Packagename.funtionname.

Migration can be performed after pkgSchemaNaming is set to true.

If pkgSchemaNaming is set to false, packages can be split.

When bas_lookup_misc_pkg is calling insert_fnd_data_change_logs, insert_fnd_data_change_logs will be not migrated.
