6c3f97399a Rename internal "toggledlog" package to "tlog"
tlog is used heavily everywhere and deserves a shorter name.

Renamed using sed magic, without any manual rework:

   find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +

09e88f31d1 toggledlog: assume command of color handling
We want to use colored error messages also outside of main,
so let's handle it in the logging package.

The fatal logger now automatically prints red.

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".

5b1eed35ee fusefrontend: Utimens: convert ENOENT to EBADF
If /proc/self/fd/X did not exist, the actual error is that the file
descriptor was invalid.

go-fuse's pathfs prefers using an open fd even for path-based operations
but does not take any locks to prevent the fd from being closed.
Instead, it retries the operation by path if it get EBADF. So this
change allows the retry logic to work correctly.

This fixes the error

    rsync: failed to set times on "/tmp/ping.Kgw.mnt/linux-3.0/[...]/.dvb_demux.c.N7YlEM":
    No such file or directory (2)

that was triggered by pingpong-rsync.bash.

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.

0c80cca674 toggledlog: convert remaing naked fmt.Print*
Several fatal errors were just printed to stdout, which
meant they were invisible when running the test suite.

Fix this by introducing toggledlog.Fatal and convert as
follows:

Fatal errors     -> toggledlog.Fatal
Warnings         -> toggledlog.Warn
Password prompts -> fmt.Fprintf

f2d208c464 configfile: use map[flagIota] for feature flags

b97268c948 configfile: bake the "Creator" gocryptfs version into the file
This field is added for the convenience of users and
may help them to identify which gocryptfs version
they need to mount a filesystem.

The same information is essentially contained in FeatureFlags,
but this is more difficult to decode for humans.

It is completely ignored programmatically (also by older gocryptfs
versions).

a602e798b1 fusefrontend: report an error if all files in a directory were invalid
Just presenting an empty directory means that the user does not know
that things went wrong unless he checks the syslog or tries to delete
the directory.

It would be nice to report the error even if only some files were
invalid. However, go-fuse does not allow returning the valid
directory entries AND an error.

72f8915843 tests: add v0.9 example filesystem with a 255-byte filename

2e2ee0a038 main: print relative path in the init success message
... but only if the relative path does not start with "..".

Makes the message easier to grasp. Example:

  $ gocryptfs -init -scryptn=10 v0.9
  [...]
  The filesystem has been created successfully.

Before:
  You can now mount it using: gocryptfs /home/jakob/src/github.com/rfjakob/gocryptfs/integration_tests/example_filesystems/v0.9 MOUNTPOINT

After:
  You can now mount it using: gocryptfs v0.9 MOUNTPOINT

5dd9576a11 fusefrontend: replace unreliable "fd < 0" check
... with the "released" boolean.

For some reason, the "f.fd.Fd() < 0" check did not work reliably,
leading to nil pointer panics on the following wlock.lock().

The problem was discovered during fsstress testing and is unlikely
to happen in normal operations.

With this change, we passed 1700+ fsstress iterations.
