874e4fb5e9 cryptocore: rename "BackendTypeEnum" -> "AEADTypeEnum" 
There are two independent backends, one for name encryption,
the other one, AEAD, for file content.

"BackendTypeEnum" only applies to AEAD (file content), so make that
clear in the name.

e032539e2c cryptocore: use eme v1.1 interface 
Version 1.1 of the EME package (github.com/rfjakob/eme) added
a more convenient interface. Use it.

Note that you have to upgrade your EME package (go get -u)!

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

db5782028a tests: skip tests with -openssl=false on Go 1.4 and lower 
Go versions 1.4 and lower lack NewGCMWithNonceSize(), which causes
a panic in the test.

a00402cc47 cryptocore: rename "gcm" variable to generic "aeadCipher" 
As we now also support AES-SIV the old name is no longer
correct.

bb52937834 cryptocore: derive 512-bit key for AES-SIV 
AES-SIV uses 1/2 of the key for authentication, 1/2 for
encryption, so we need a 64-byte key for AES-256. Derive
it from the master key by hashing it with SHA-512.

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.

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' {} +

906172938a stupidgcm: skip tests on Go 1.4 and older 
Quoting from the patch:

	We compare against Go's built-in GCM implementation. Since stupidgcm only
	supports 128-bit IVs and Go only supports that from 1.5 onward, we cannot
	run these tests on older Go versions.
