cmount: when setting dates discard out of range dates
...
It appears that sometimes Windows/WinFSP/cgofuse sends dates which are
the epoch to rclone. These dates appear as 1601-01-01 00:00:00 plus
or minus the timezone.
These dates aren't being sent from rclone.
This patch filters dates out before 1601-01-02 so rclone does not
attempt to set them.

mount: replace use of WriteAt with Write for cache mode >= writes and O_APPEND
...
os.File.WriteAt returns an error if a file was opened with O_APPEND.
This replaces it with os.File.Write if the file was opened with
O_APPEND.

mount: allow files of unkown size to be read properly
...
Before this change, files of unknown size (eg Google Docs) would
appear in file listings with 0 size and would only allow 0 bytes to be
read.
This change sets the direct_io flag in the FUSE return which bypasses
the cache for these files. This means that they can be read properly.
This is compatible with some, but not all applications.

mount,cmount: clip the number of blocks to 2^32-1 on macOS
...
OSX FUSE only supports 32 bit number of blocks which means that block
counts have been wrapping. This causes f_bavail to be 0 which in turn
causes problems with programs like borg backup.
Fixes #2356

mount, cmount: remove addition of O_CREATE to flags on file open #2141
...
Previously this was adding it in to all file opens which was causing
inefficiencies under Windows where it stats the file using
open/fstat/close.
This change will make stat operations run much quicker under Windows
as they won't have to open the underlying file
This problem was introduced in61b6159a05336bd7ba105766de2d2ff171f7fb81
where we added O_CREATE to all file opens and creates.

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.

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.

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.

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.
