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.

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.

c92190bf07 stupidgcm: add our own thin wrapper around openssl gcm
...complete with tests and benchmark.

This will allow us to get rid of the dependency to spacemonkeygo/openssl
that causes problems on Arch Linux
