vfs: reduce directory cache cleared by poll-interval
...
Reduce the number of nodes purged from the dir-cache when ForgetPath is
called. This is done by only forgetting the cache of the received path
and invalidating the parent folder cache by resetting *Dir.read.
The parent will read the listing on the next access and reuse the
dir-cache of entries in *Dir.items.

fs: update ChangeNotifier interface
...
This introduces a channel to the ChangeNotify function, which can be
used to update the poll-interval and cleanly exit the polling function.

vfs: Only make the VFS cache if --vfs-cache-mode > Off
...
This stops the cache cleaner running unnecessarily and saves
resources.
This also helps with issue #2227 which was caused by a second mount
deleting objects in the first mounts cache.

vfs: Make OpenFile and friends return EINVAL if O_RDONLY and O_TRUNC
...
Before this change Open("name", os.O_RDONLY|os.O_TRUNC) would have
truncated the file. This is what Linux does, but is counterintuitive.
POSIX states this is undefined, so return an error in this case
instead. This preserves the invariant O_RDONLY => file is not
changed.

Break the fs package up into smaller parts.

The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
