Avoid collision ComplexTypes Type name and resolve it.

[soh335]

Hi, it's still idea codes and I'm not good at soap. But I want to listen maintainers opinions. So I created p-r.

Some wsdl has same ComplexType name in different namespace schemas.
So currently we export it with syntax error (Request redeclared in this block), because we export all ComplexTypes to file as flat.

So this code found collision names, and rename it with number suffix.

    <wsdl:types>
        <xs:schema xmlns:ns1="xxx" attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="vvv">
            <xs:complexType name="Request">
                <xs:sequence>
                          .....
                </xs:sequence>
            </xs:complexType>
        </xs:schema>
        <xs:schema xmlns:ns2="xxx" attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="zzz">
            <xs:complexType name="Request">
                <xs:sequence>
                          .....
                </xs:sequence>
            </xs:complexType>
        </xs:schema>
        <xs:schema xmlns:ns1="vvv" xmlns:ns2="zzz"  attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="yyy">
            <xs:element name="do1">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element minOccurs="0" name="param0" nillable="true" type="ns1:Request"/>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
            <xs:element name="do2">
                <xs:complexType>
                    <xs:sequence>
                        <xs:element minOccurs="0" name="param0" nillable="true" type="ns2:Request"/>
                    </xs:sequence>
                </xs:complexType>
            </xs:element>
        </xs:schema>
    </wsdl:types>
