configfile: switch to 128-bit IVs for master key encryption
...
There is no security reason for doing this, but it will allow
to consolidate the code once we drop compatibility with gocryptfs v1.2
(and earlier) filesystems.

configfile: warn about missing feature flags

configfile: use map[flagIota] for feature flags

This should make things saner and more extensible. It prepares
the infrastructure for "required feature flags" that will be used

configfile: bake the "Creator" gocryptfs version into the file

This field is added for the convenience of users and
may help them to identify which gocryptfs version
they need to mount a filesystem.
The same information is essentially contained in FeatureFlags,
but this is more difficult to decode for humans.
It is completely ignored programmatically (also by older gocryptfs
versions).
