57612a278b configfile: rename "kdf.go" -> "scrypt.go" 
This really only handles scrypt and no other key-derivation functions.
Renaming the files prevents confusion once we introduce HKDF.

renamed:    internal/configfile/kdf.go -> internal/configfile/scrypt.go
renamed:    internal/configfile/kdf_test.go -> internal/configfile/scrypt_test.go

477071d673 speed: fix build for Go 1.4 and lower 
Old Go versions miss cipher.NewGCMWithNonceSize, which causes:

1e03e059fa Implement "gocryptfs -speed" 
A crypto benchmark mode like "openssl speed".

Example run:

  $ ./gocryptfs -speed
  AES-GCM-256-OpenSSL 	 180.89 MB/s	(selected in auto mode)
  AES-GCM-256-Go      	  48.19 MB/s
  AES-SIV-512-Go      	  37.40 MB/s

b056776a01 tests: adapt dir overwrite test for Go 1.8 
In Go 1.8, os.Rename refuses to overwrite an empty directory.
Switch to syscall.Rename, which still does the right thing.

7fbe69bfa6 tests.bash: OSX compat: use "flock -n" and skip openssl build 
Mac OS X flock does not support "--nonblock", but does support "-n":
https://github.com/discoteq/flock/blob/master/man/flock.1.ronn

Skip the openssl build because it requires
1) openssl
2) fixing the import paths in gocryptfs

07b4b9d60b Travis: set clone depth to 100 
Otherwise the build fails once you have more than 50 commits
since the last tag.

You'd get:

$ ./build.bash
fatal: No names found, cannot describe anything.

3784901fce readpassword: limit password length to 1000 bytes 
This used to hang at 100% CPU:

    cat /dev/zero | gocryptfs -init a

...and would ultimately send the box into out-of-memory.

The number 1000 is chosen arbitrarily and seems big enough
given that the password must be one line.

8adfbf2dc3 Check for trailing garbage after the password 
From the comment:

// CheckTrailingGarbage tries to read one byte from stdin and exits with a
// fatal error if the read returns any data.
// This is meant to be called after reading the password, when there is no more
// data expected. This helps to catch problems with third-party tools that
// interface with gocryptfs.
