prefer_openssl: autodetect whether to use OpenSSL or Go GCM
...
Go GCM is faster than OpenSSL if the CPU has AES instructions
and you are running Go 1.6+.
The "-openssl" option now defaults to "auto".
"gocryptfs -debug -version" displays the result of the autodetection.
See https://github.com/rfjakob/gocryptfs/issues/23 for details and
benchmarks.

fusefrontend: fix wlock memory leak
...
The write lock was not freed on release, causing a slow memory leak.
This was noticed by running extractloop.bash for 10 hours.

stupidgcm: set dummy locking callback.
...
In general, OpenSSL is only threadsafe if you provide a locking function
through CRYPTO_set_locking_callback. However, the GCM operations that
stupidgcm uses never call that function.
To guard against that ever changing, set a dummy locking callback
that crashes the app.

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.

Revert "stupidgcm: print openssl error stack before panicing"
...
This did not help in debugging the openssl <= 1.0.1c issue at all
and makes the code more complex. Keep it simple.
