This patch will:
- add --daemon-wait flag to control the time to wait for background mount
- remove dependency on sevlyar/go-daemon and implement backgrounding directly
- avoid setsid during backgrounding as it can result in race under Automount
- provide a fallback PATH to correctly run `fusermount` under systemd as it
runs mount units without standard environment variables
- correctly handle ^C pressed while background process is being setting up
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.
Includes adding support for additional size input suffix Mi and MiB, treated equivalent to M.
Extends binary suffix output with letter i, e.g. Ki and Mi.
Centralizes creation of bit/byte unit strings.
Previously rclone set --daemon-timeout to 15m by default. However
osxfuse seems to be ignoring that value since it is above the maximum
value of 10m. This is conjecture since the source of osxfuse is no
longer available.
Setting the value to 10m seems to resolve the problem.

Add --network-mode option to activate mounting as network drive without having to set volume prefix.
Add support for automatic drive letter assignment (not specific to network drive mounting).
Allow full network share unc path in --volname, which will also implicitely activate network drive mounting.
Allow full network share unc path as mountpoint, which will also implicitely activate network drive mounting, and the specified path will be used as volume prefix and the remote will be mounted on an automatically assigned drive letter instead.
This limit was previously 4k set in 59026c4761 however leaf
names above 1k now produce an IO error.
WinFSP seems to have its own method for dropping too long file names
above 255 long.
Before this change `rclone mount` would give this error on FreeBSD
mount helper error: mount_fusefs: -o timeout=: option not supported
Because the default value for FreeBSD was set to 15m for
--daemon-timeout and that FreeBSD does not support the timeout option.
This change sets the default for --daemon-timeout to 0 on FreeBSD
which fixes the problem.
Fixes#3610
