35219d0022 fusefrontend: log missing gocryptfs.diriv
This can happen during normal operation when the directory has
been deleted concurrently. But it can also mean that the
gocryptfs.diriv is missing due to an error, so log the event
at "info" level.

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.

3288d98703 fusefrontend: fix PlaintextNames versions of Mkdir, Rmdir
The "!fs.args.DirIV" special case was removed by b17f0465c7
but that, by accident, also removed the handling for
PlaintextNames.

Re-add it as an explicit PlaintextNames special case.

Also adds support for removing directories that miss their
gocryptfs.diriv file for some reason.

b17f0465c7 Drop deprecated "-diriv" option
The DirIV feature flag is already mandatory, dropping the command
line option is the final step.

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' {} +

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.

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.
