Though in practice they usually not used, not tested, and as was revealed by Ido, this functionality is not working properly. There are few places inside ACL build code-path that need to be addressed.

Till now, only first format was supported. Extend test-acl to support both formats, mainly for testing and demonstrating purposes. To control desired behavior '--ipv6' command-line option is extend to accept an optional argument: To be more precise: '--ipv6' - use 4x4B fields format (default behavior) '--ipv6=4B' - use 4x4B fields format (default behavior) '--ipv6=8B' - use 2x8B fields format app/acl: use posix functions for network address parsing Also replaced home brewed IPv4/IPv6 address parsing with inet_pton() calls.

Till now, only first format was supported. Extend test-acl to support both formats, mainly for testing and demonstrating purposes. To control desired behavior '--ipv6' command-line option is extend to accept an optional argument: To be more precise: '--ipv6' - use 4x4B fields format (default behavior) '--ipv6=4B' - use 4x4B fields format (default behavior) '--ipv6=8B' - use 2x8B fields format Also replaced home brewed IPv4/IPv6 address parsing with inet_pton() calls.
