a2510efe12 reverse: use per-purpose nonce generation 
Also pull all the deterministic nonce code into fusefrontend_reverse
to greatly simplify the normal code path.

e9bb8b800c reverse: switch from GCM-SIV to AES-SIV 
GCM-SIV is not yet finalized, and the reference implemenation is
painfully slow at about 2 MB/s. Switch to AES-SIV.

cc2a75b050 Mount v0.6 and older filesystems as read-only 
This is part of the phase-out of very old filesystems.

See https://github.com/rfjakob/gocryptfs/wiki/Compatibility for
more info.

3234b9b5ce tests: update config_test example files 
Recreate the files so they carry all feature flags.

Also, create them with "-scryptn 10" to speed up the tests.

6c3f97399a Rename internal "toggledlog" package to "tlog" 
tlog is used heavily everywhere and deserves a shorter name.

Renamed using sed magic, without any manual rework:

   find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +

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.

0c80cca674 toggledlog: convert remaing naked fmt.Print* 
Several fatal errors were just printed to stdout, which
meant they were invisible when running the test suite.

Fix this by introducing toggledlog.Fatal and convert as
follows:

Fatal errors     -> toggledlog.Fatal
Warnings         -> toggledlog.Warn
Password prompts -> fmt.Fprintf

ca54b665e3 main: print actual error from LoadConfFile() 
It may not have been a "Wrong password" after all.

Also, push down disabling the warning so LoadConfFile() can
warn about things that matter.

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.

b97268c948 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).

37a9b4c3ee Enable openssl in tests to support old Go versions 
Go 1.4 and older do not support 128-bit IVs which caused
the tests to panic.
