The upstream library rclone uses for rclone mount no longer supports
freebsd. Not only is it broken, but it no longer compiles.
This patch disables rclone mount for freebsd.
However all is not lost for freebsd users - compiling rclone with the
`cmount` tag, so `go install -tags cmount` will install a working
`rclone mount` command which uses cgofuse and the libfuse C library
directly.
Note that the binaries from rclone.org will not have mount support as
we don't have a freebsd build machine in CI and it is very hard to
cross compile cmount.

Since version 3 of fuse libfuse no longer does anything when given the
nonempty option and it's default is to allow mounting over non empty
directories like normal mount does.
Some versions of libfuse give an error when using `--allow-non-empty`
which is annoying for the user.
We now do this check ourselves so we no longer need to pass the option
to libfuse.
Fixes#3562
Before this change, the device name was always the remote:path rclone
was configured with. However this can contain sensitive information
and it appears in the `mount` output, so `--devname` allows the user
to configure it.

It was discovered `rclone mount` (but not `rclone cmount`) cached
directories after rename which it shouldn't have done.
This caused IO errors when trying to access files in renamed
directories on bucket based file systems.
This turned out to be the kernel caching the directories as basil/fuse
sets their expiry time to 60s for some reason.
This fix invalidates the relevant kernel cache entries in the for the
directories which fixes the problem.

By default the timeout is 60s which isn't long enough for long
transactions. The symptoms are rclone just quitting for no reason.
Supplying the --daemon-timeout flag fixes this causing the kernel to
wait longer for rclone.
When running `rclone mount`, there were 2 signal handlers for `os.Interrupt`.
Those handlers would run concurrently and in some cases cause either unmount or `atexit.Run()` being skipped.
In addition `atexit.Run()` will get called in `resolveExitCode` to ensure cleanup on errors.
Before this change we would unconditionally set the OSXFUSE options
noappledouble and noapplexattr.
However the noapplexattr options caused problems with copies in the
Finder.
Now the default for noapplexattr is false so we don't add the option
by default and the user can override the defaults using the
--noappledouble and --noapplexattr flags.
Before this change rclone would set the volume name from the
remote:path normally. However this has `:` and `/` in which make it
difficult to use in macOS.
Now rclone will remove the special characters and replace them with
spaces. It also allows the volume name to be set with the --volname
flag.
