fc32fee4ad mount, cmount: add --attr-timeout to control attribute caching in kernel
This flag allows the attribute caching in the kernel to be controlled.
The default is 0s - no caching - which is recommended for filesystems
which can change outside the control of the kernel.

Previously this was at the default meaning it was 60s for mount and 1s
for cmount.  This showed strange effects when files changed on the
remote not via the kernel.  For instance Caddy would serve corrupted
files for a while when serving from an rclone mount when a file
changed on the remote.

54deb01f00 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.

11da2a6c9b 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.

94adf4f43b cmount: translate FUSE open flags into OS flags
On Windows the fuse.O_* flags do not have the same values as the
os.O_* flags so translate between the two representations.  They are
mostly the same which is why this hasn't caused a problem before.

b259f8b752 cmount, mount, mountlib: make --read-only reject modify operations
Normally mount/cmount use `-o ro` to get the kernel to mark the fs as
read only.  However this is ignored by WinFsp, so in addition if
`--read-only` is in effect then return EROFS ("Read only File System")
from all methods which attempt to modify something.
