Current way of checking whether mountpoint has been already mounted (directory
list) can result in race if rclone runs under Automount (classic or systemd).
This patch adopts Linux ProcFS for the check. Note that mountpoint is considered
empty if it's tagged as "mounted" by autofs. Also ProcFS is used to check whether
rclone mount was successful (ie. tagged by a string containing "rclone").
On macOS/BSD where ProcFS is unavailable the old method is still used.
This patch also moves a few utility functions unchanged to utils.go:
CheckOverlap, CheckAllowings, SetVolumeName.
This replaces built-in os.MkdirAll with a patched version that stops the recursion
when reaching the volume part of the path. The original version would continue recursion,
and for extended length paths end up with \\? as the top-level directory, and the error
message would then be something like:
mkdir \\?: The filename, directory name, or volume label syntax is incorrect.
Before this change the union's feature flags were a strict AND of the
underlying remotes. This means that a union of a local disk (which can
Move but not Copy) and a bucket based remote (which can Copy but not
Move) could neither Move nor Copy.
This fix advertises Move in the union if all the remotes can Move or
Copy. It also implements Move as Copy+Delete (like rclone does
normally) if the underlying union does not support Move.
This enables renames to work with unions of local disk and bucket
based remotes expected.
Fixes#5632
Before this change file handles could get closed while the truncate
the file handles loop was running.
This would mean that ocassionally an ECLOSED (which is translated into
EBADF by cmd/mount) would spuriously be returned if Release happened
to happen in the middle of a Truncate call (Setattr called with
size=0).
This change ignores the ECLOSED while truncating file handles.

This was started in
3626f10f26 pcloud: add sha256 support - fixes#5496
But this support turned out to be incomplete and caused the
integration tests to fail.
After updating rclone's dependencies these tests started failing on
windows/386
- TestInternalDoubleWrittenContentMatches
- TestInternalMaxChunkSizeRespected
The failures look like this. The root cause is unknown. The `Wait(n=1)
would exceed context deadline` errors come from golang.org/x/time/rate
but it isn't clear what is calling them.
