97d8340bd8 configfile: add Validate() function, support FlagXChaCha20Poly1305
We used to do validation using lists of mandatory feature flags.

With the introduction of XChaCha20Poly1305, this became too
simplistic, as it uses a different IV length, hence disabling
GCMIV128.

Add a dedicated function, Validate(), with open-coded validation
logic.

The validation and creation logic also gets XChaCha20Poly1305
support, and gocryptfs -init -xchacha now writes the flag into
gocryptfs.conf.

4764a9bde0 Add partial XChaCha20-Poly1305 support (mount flag only)
Mount flag only at the moment, not saved to gocryptfs.conf.

d0bc7970f7 full stack: implement HKDF support
...but keep it disabled by default for new filesystems.

We are still missing an example filesystem and CLI arguments
to explicitely enable and disable it.

GCM-SIV is not yet finalized, and the reference implemenation is
painfully slow at about 2 MB/s. Switch to AES-SIV.

0f4d350136 configfile: warn about missing feature flags
The plan is to drop support for the oldest filesystem versions
in gocryptfs v1.0. For now, we only warn the user.

f2d208c464 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
to deprecate old gocryptfs version.
