a67688dcc7 mount,cmount,mount2: add --direct-io flag to force uncached access
This change adds the --direct-io flag to the mount. This means the
page cache is completely bypassed for reads and writes. No read-ahead
takes place. Shared mmap is disabled.

This is useful to accurately read files which may change length
frequently on the source.

fd8faeb0e6 vfs: fix unicode normalization on macOS - fixes #7072
Before this change, the VFS layer did not properly handle unicode normalization,
which caused problems particularly for users of macOS. While attempts were made
to handle it with various `-o modules=iconv` combinations, this was an imperfect
solution, as no one combination allowed both NFC and NFD content to
simultaneously be both visible and editable via Finder.

After this change, the VFS supports `--no-unicode-normalization` (default `false`)
via the existing `--vfs-case-insensitive` logic, which is extended to apply to both
case insensitivity and unicode normalization form.

This change also adds an additional flag, `--vfs-block-norm-dupes`, to address a
probably rare but potentially possible scenario where a directory contains
multiple duplicate filenames after applying case and unicode normalization
settings. In such a scenario, this flag (disabled by default) hides the
duplicates. This comes with a performance tradeoff, as rclone will have to scan
the entire directory for duplicates when listing a directory. For this reason,
it is recommended to leave this disabled if not needed. However, macOS users may
wish to consider using it, as otherwise, if a remote directory contains both NFC
and NFD versions of the same filename, an odd situation will occur: both
versions of the file will be visible in the mount, and both will appear to be
editable, however, editing either version will actually result in only the NFD
version getting edited under the hood. `--vfs-block-norm-dupes` prevents this
confusion by detecting this scenario, hiding the duplicates, and logging an
error, similar to how this is handled in `rclone sync`.

af8ba18580 mount: disable mount for freebsd
The upstream library rclone uses for rclone mount no longer supports
freebsd. Not only is it broken, but it no longer compiles.

This patch disables rclone mount for freebsd.

However all is not lost for freebsd users - compiling rclone with the
`cmount` tag, so `go install -tags cmount` will install a working
`rclone mount` command which uses cgofuse and the libfuse C library
directly.

Note that the binaries from rclone.org will not have mount support as
we don't have a freebsd build machine in CI and it is very hard to
cross compile cmount.

See: https://github.com/bazil/fuse/issues/280
Fixes #5843

a6f6a9dcdf mount,mount2,cmount: fix --allow-non-empty #3562
Since version 3 of fuse libfuse no longer does anything when given the
nonempty option and it's default is to allow mounting over non empty
directories like normal mount does.

Some versions of libfuse give an error when using `--allow-non-empty`
which is annoying for the user.

We now do this check ourselves so we no longer need to pass the option
to libfuse.

Fixes #3562

f4c40bf79d mount: add --devname to set the device name sent to FUSE for mount display
Before this change, the device name was always the remote:path rclone
was configured with. However this can contain sensitive information
and it appears in the `mount` output, so `--devname` allows the user
to configure it.

e43b5ce5e5 Remove github.com/pkg/errors and replace with std library version
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.

This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.

93353c431b selfupdate: dont detect FUSE if build is static
Before this patch selfupdate detected ANY build with cmount tag as a build
having libFUSE capabilities. However, only dynamic builds really have it.
The official linux builds are static and have the cmount tag as of the time
of this writing. This results in inability to update official linux binaries.
This patch fixes that. The build can be fixed independently.

e92cb9e8f8 mount: more user friendly mounting as network drive on windows
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.

f7d9b15707 cmount: don't call host.Umount if a signal has been received
Before this change cgofuse and libatexit would race to see who could
unmount the file system with unpredicatable results. On Linux it could
report an error or not, depending.

This change checks to see if umount is beng called from a signal and
if so leaves the unmounting to cgofuse/libfuse.

0ee16b51c4 mount: On Windows don't add -o uid/gid=-1 if user supplies -o uid/gid.
Before this change if the user supplied `-o uid=XXX` then rclone would
write `-o uid=-1 -o uid=XXX` so duplicating the uid value.

After this change rclone doesn't write the default `-1` version.

This fix affects `uid` and `gid`.

473e3c3eb8 mount/cmount: implement --daemon-timeout flag for OSXFUSE
By default the timeout is 60s which isn't long enough for long
transactions.  The symptoms are rclone just quitting for no reason.
Supplying the --daemon-timeout flag fixes this causing the kernel to
wait longer for rclone.

9d8d7ae1f0 mount,cmount: make --noappledouble --noapplexattr and change defaults #2287
Before this change we would unconditionally set the OSXFUSE options
noappledouble and noapplexattr.

However the noapplexattr options caused problems with copies in the
Finder.

Now the default for noapplexattr is false so we don't add the option
by default and the user can override the defaults using the
--noappledouble and --noapplexattr flags.

6ce32e4661 mount,cmount: Add --volname flag and remove special chars from it #2287
Before this change rclone would set the volume name from the
remote:path normally.  However this has `:` and `/` in which make it
difficult to use in macOS.

Now rclone will remove the special characters and replace them with
spaces.  It also allows the volume name to be set with the --volname
flag.

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.
