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.

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.

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' {} +

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.
