benchmarks.

Encrypt path in statfs() calls

Paths in statfs() calls were not encrypted resulting in
an Function not implemented error, when the unencrypted
path didn't exist in the underlying (encrypted)
filesystem.

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.
