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.

f8da264222 tests: smarter error handling in ResetTmpDir

right thing to do.

Gets rid of spurious fusermount error messages.

09c16ed2a7 tests: extractloop: add loopback support 
loopback is an example app that comes with the go-fuse lib.
It uses all the same APIs as gocryptfs, minus the encryption.

1c54fcd04b tests: use unmount wrapper in ResetTmpDir 
This should make it work on OSX.

Also, split unmount into two functions. Depending on what you
want,

* UnmountErr returns the resulting error
* UnmountPanic panics if the error was not nil

7f3ede473e tests: fix shadow warning 
"go tool vet -shadow=true" complained about the md5 package
being shadowed by variables called "md5".
Fix by using the Md5hex helper and dropping the md5 import.

9d17fdb206 tests: OSX: cast st.Blksize to int64 
On Linux, Blksize is already int64. But on OSX
it is int32 and that caused a compile failure.

9b725c15cf syscallcompat: OSX: add Fallocate and Openat wrappers 
...and convert all calls to syscall.{Fallocate,Openat}
to syscallcompat .

Both syscalls are not available on OSX. We emulate Openat and just
return EOPNOTSUPP for Fallocate.

f2b4d57068 fusefrontend: coalesce grows in Truncate() 
We were growing the file block-by-block which was pretty
inefficient. We now coalesce all the grows into a single
Ftruncate. Also simplifies the code!

Simplistic benchmark: Before:

  $ time truncate -s 1000M foo
  real	0m0.568s

After:

  $ time truncate -s 1000M foo
  real	0m0.205s

02b6d3067d test: split up integration_tests 
...into "matrix" and "normal".

Also:
* Make running multiple packages in parallel safe, see
  http://stackoverflow.com/questions/23715302/go-how-to-run-tests-for-multiple-packages
* Don't depent on test_helper.TmpDir and friends to have a terminating slash

2720cd7b0d tests: give "-plaintextnames" its own test package 
...and add tests for checking that gocryptfs.diriv
does not get created.

The main "integration_tests" package has become quite
big and convoluted over time.

This small separate package should make writing tests
for "-plaintextnames" easier.

As seen in "fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir",
we need more of them.

b558901e66 Drop deprecated "-gcmiv128" option

line option is the final step.

80fc3532f6 tests: make tests for unsupported FSs more compact 
There is no need to test that deprecated command-line options
produce an error. I trust the flags package.

Also split the example_filesystem helper functions into a
separate file.

8a2e1a543a tests: add v0.7-plaintextnames example filesystem 
The v0.6-plaintextnames example FS lacks the GCMIV128 feature
flag, is no longer mountable and can no longer be used for testing.

Add a new "-plaintextnames" filesystem created by gocryptfs v0.7.
There have been no format changes to "-plaintextnames" since then.

218bf83ce3 tests: spin off TestPasswd from TestInit 
Also, capture all stderr and stdout but pass "-q".
This way we get to see error messages if there are any, or
spurious output when there should be none due to "-q".

37d824c9a8 test: add pingpong.bash and pingping-rsync.bash 
Mounts two gocryptfs filesystems, "ping" and "pong" and moves the
linux-3.0 kernel tree back and forth between them.

When called as "pingpong-rsync.bash" it uses "rsync --remove-source-files"
for moving the files, otherwise plain "mv".

5da292828c fusefrontend: fix chown on dangling symlinks 
We (actually, go-fuse) used to call Chown() instead of Lchown()
which meant that the operation would fail on dangling symlinks.

Fix this by calling os.Lchown() ourself. Also add a test case
for this.

c2a5303eeb tests: split example_filesystems into its own package 
Running these tests from integration_tests' TestMain() was awkward
because they were run twice with unchanged settings.
integration_tests tests everything with OpenSSL and with native
Go crypto, but this does not take affect for the example filesystems.

To make this work, test_helpers is also split into its own package.
