c9f4400e6d Replace all calls to naked panic() with log.Panic() 
We want all panics to show up in the syslog.

012152f3d1 fusefrontend: I/O error instead of panic on all-zero nonce 
Running xfstests generic/075 on tmpfs often triggered a panic
for what seems to be a tmpfs bug.

Quoting from the email to lkml,
http://www.spinics.net/lists/kernel/msg2370127.html :

	tmpfs seems to be incorrectly returning 0-bytes when reading from
	a file that is concurrently being truncated.

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.

abd61d968d contentenc: rename constant "IVBitLen" to "DefaultIVBits" and clarify comment

7b22b426b9 contentenc: rename PlaintextRange and CiphertextRange 
The name could be misunderstood and actually caused a bug:
doWrite used to always preallocate 4128 instead of the actual
data length.

7e92ebe16a Rename nametransform, contentenc source files 
Let's have shorter names, and merge *_api.go into the "main"
file.

No code changes.

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' {} +
