By this it is possible to read and check just the first u64 of the corresponding
structs in order to identify the items.
This is needed for the fuse implementation in order to get entries based on the
archive offset, used as inode.
Directories are referenced by the offset to the goodbye tail while other items
are referenced by the offset of the filename followed by the entry.

This structure contains all the attributes allowing to easily store those within
a e.g. dir buffer.

Not all filesystems support features such as xattrs,acl,... and trying to get
them is rather expensive.
By getting the supported features based on the filesystem magic and masking the
user set feature flags, unsupported features are excluded rather inexpensively
while encoding the archive.

In addition to the format definition, the traits needed for sorting of xattr
entries by name are derived.
