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.
