777eb8e62f reverse: rename types to reverseXYZ 
...to prevent confusion with the forward variants.

FS   -> reverseFS
file -> reverseFile

Also add an incomplete read implementation.

fca1b82417 fusefrontend: relay Utimens to go-fuse 
Commit af5441dcd9 has caused a
regression ( https://github.com/rfjakob/gocryptfs/issues/35 )
that is fixed by this commit.

The go-fuse library by now has all the syscall wrappers in
place to correctly handle Utimens, also for symlinks.

Instead of duplicating the effort here just call into go-fuse.

Closes #35

8f1e51789d tests: set the times on a symlink 
This currently fails as reported in

Also remove the spurious sleep in the test.

af5441dcd9 fusefrontend: use NsecToTimespec() for Utimens 
This fixes a build problem on 32-bit hosts:

  internal/fusefrontend/file.go:400: cannot use a.Unix() (type int64) as
  type int32 in assignment
  internal/fusefrontend/file.go:406: cannot use m.Unix() (type int64) as
  type int32 in assignment

It also enables full nanosecond timestamps for dates
after 1970.

02aab5d21f Drop obsolete .drone.yml 
Drone CI may make sense in the future when I set up a private
instance that supports FUSE, but for now it provides no advantages
to Travis CI.

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

"go tool vet -shadow=true" complained about the md5 package
being shadowed by variables called "md5".

9d17fdb206 tests: OSX: cast st.Blksize to int64

it is int32 and that caused a compile failure.

e574a6cc1f nametransform: hide detailed padding error behind the debug flag 
unPad16 returns detailed errors including the position of the
incorrect bytes. Kill a possible padding oracle by lumping
everything into a generic error.

The detailed error is only logged if debug is active.

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

e994ffa27d fusefrontend: handle dir-overwrites-dir on XFS 
XFS returns a different error code if you try to overwrite
a non-empty directory with a directory:

XFS:  mv: cannot move ‘foo’ to ‘bar/foo’: File exists
ext4: mv: cannot move 'foo' to 'bar/foo': Directory not empty

So have EEXIST trigger the Rmdir logic as well.

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.
