Added:
 * IDataTypeDomain interface;
 * method DataTypeFactory::registerDataTypeDomain for registering domains;
 * DataTypeDomainWithSimpleSerialization domain base class with simple serialization/deserialization;
 * Concrete IPv4 and IPv6 domain implementations: DataTypeDomanIPv6 and DataTypeDomanIPv4;

Updated:
 * IDataType text serialization/deserialization methods;
 * IDataType implementation to use domain for text serialization/deserialization;
 * Refactored implementation of the IPv4/IPv6 functions to use formatIPv4/v6 and parseIPv4/v6 from Common/formatIPv6.h;

Tests:
 * Added test cases for IPv4 and IPv6 domains.
 * Updated IPv4/v6 functions tests to validate more cases;
 * Added performance tests for IPv4 and IPv6 related functions;

This is essentially to help implementing the `getReturnType` of
aggregation function susceptible to provoque overflow (such as
`sumMap`).

Use getpwnam_r instead of getpwnam.
Fix style.
