When a process has its working dir inside the mount,
the only way we notice is that we get EBUSY when trying
to unmount.
We used to lazy-unmount in this case, but this means
pulling the rug from under the process.
For example, bash will start throwing
cd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
messages.
Fixes https://github.com/rfjakob/gocryptfs/issues/533
Directly accessing the Nodes does not work properly,
as there is no way to attach a newly LOOKUPped Node
to the tree. This means Path() does not work.
Use an actual mount instead and walk the tree.
Horribly broken, but it compiles.

We need

to fix a crash reported in https://github.com/rfjakob/gocryptfs/issues/430 :

This patch is only in the v2.x.x branch. Upgrade to v2, as the
old API is also supported there.
Running
git grep hanwen/go-fuse | grep -v hanwen/go-fuse/v2
to check for forgotten references comes back clean.
Use exec.LookPath() to find fusermount in the user's PATH
first. Fall back to /bin/fusermount for the case that PATH
is not set, like go-fuse does.

fusermount3 (i.e. fusermount from libfuse 3.x) has dropped
the `nonempty` option.
Detect fusermount3 and don't add `nonempty` in this case.

This adds support for gitignore-like wildcards and exclude patters in
reverse mode. It (somewhat) fixes#273: no regexp support, but the
syntax should be powerful enough to satisfy most needs.
Also, since adding a lot of --exclude options can be tedious, it adds
the --exclude-from option to read patterns from a file (or files).
The messages would still be collected via gocryptfs-logger,
but let's do it right.

Even though filesystem notifications aren't implemented for FUSE, I decided to
try my hand at implementing the autounmount feature (#128). I based it on the
EncFS autounmount code, which records filesystem accesses and checks every X
seconds whether it's idled long enough to unmount.
I've tested the feature locally, but I haven't added any tests for this flag.
I also haven't worked with Go before. So please let me know if there's
anything that should be done differently.
One particular concern: I worked from the assumption that the open files table
is unique per-filesystem. If that's not true, I'll need to add an open file
count and associated lock to the Filesystem type instead.

The cipherdir path is used as the fsname, as displayed
in "df -T". Now, having a comma in fsname triggers a sanity check
in go-fuse, aborting the mount with:
/bin/fusermount: mount failed: Invalid argument
fuse.NewServer failed: fusermount exited with code 256
Sanitize fsname by replacing any commas with underscores.

When mounted via /etc/fstab like this,
/a /b fuse.gocryptfs default 0 0
we always get extra options passed. As reported by @mahkoh
at https://github.com/rfjakob/gocryptfs/pull/233 :
mount passes `-o noexec` if `-o user` is set and `-o exec` is not set.
If both `-o user` and `-o exec` are set, it passes `-o exec`.
Make these options work, and in addtion, also make -suid and -rw
work the same way.

A few places have called tlog.Warn.Print, which directly
calls into log.Logger due to embedding, losing all features
of tlog.
Stop embedding log.Logger to make sure the internal functions
cannot be called accidentially and fix (several!) instances
that did.
