BSD file's support "flags". These have some similarity with xattr, but
for specific features, rather than general purpose key/values.

Rather than an arbitrary election of hashing the xattr value with SHA1
to avoid leaking the value. By going with base64 encoding it allows for
the possibility of restoring a directory with the values stored in the
manifest.

when creating a manifest from, or validating, a stream like a tar
archive, it requires thinking about some of the functions differently
than walking a directory tree.
This is the beginning of allowing for such features.

Initially only on linux platform, but could accommodate BSDs as well.
The keyword is rather a prefix of the key. So xattr keyword will have a
prefix of "xattr." followed by a suffix of its namespace and name.
The value stored in the manifest is the SHA1 digest of the extended
attribute's data.
