9f56b33e0c fusefrontend: Fix longname handling for renames with existing target 
Fixes https://github.com/rfjakob/gocryptfs/issues/170

Steps to reproduce the problem:

* Create a regular forward mount point
* Create a file with a shortname and one with a long filename
* Try to run 'mv <shortname> <longname>'

This should actually work and replace the existing file, but instead it
fails with:

    mv: cannot move '<shortname>' to '<longname>': File exists

The problem is the creation of the .name file. If the target already exists
we can safely ignore the EEXIST error and just keep the existing .name file.

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.

964e0e6b36 tests: add raw64 tests 
Also, use "%#v" instead of JSON for debug output.
This means we can unexport all fields.

btrfs gives different results, but that's not an error.

Also, simplify test_helpers.Du and several code paths.

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

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
