Add `flags` u16 field to the hole in ipfw_table_xentry structure.
Kernel has been guessing address family for supplied record based
on xent length size.
Userland, however, has been getting fixed-size ipfw_table_xentry structures
guessing address family by checking address by IN6_IS_ADDR_V4COMPAT().
Fix this behavior by providing specific IPFW_TCF_INET flag for IPv4 records.

received due to IFDISABLED, and as a result it could prevent DAD when
manually clearing IFDISABLED after that.

1. The output file that was previously written is now called the raw format.
2. Add the vmdk output format to create VMDK images.
When the format is not given, the raw output format is assumed.
