The Swift backend does not always respect the flag telling it to skip
HEADing zero-length objects. This commit fixes that for ls/lsl/lsf.
Swift returns zero length for dynamic large object files when they're
included in a files lookup, which means that determining their size
requires HEADing each file that returns a size of zero. rclone's
--swift-no-large-objects instructs rclone that no large objects are
present and accordingly rclone should not HEAD files that return zero
length.
When rclone is performing an ls / lsf / lsl type lookup, however, it
continues to HEAD any zero length objects it encounters, even with
this flag set. Accordingly, this change causes rclone to respect the
flag in these situations.
NB: It is worth noting that this will cause rclone to incorrectly
report zero length for any dynamic large objects encountered with the
--swift-no-large-objects flag set.
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.
This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

Before this change, rclone always expected --sftp-path-override to be
the absolute SSH path to remote:path/subpath which effectively made it
unusable for wrapped remotes (for example, when used with a crypt
remote, the user would need to provide the full decrypted path.)
After this change, the old behavior remains the default, but dynamic
paths are now also supported, if the user adds '@' as the first
character of --sftp-path-override. Rclone will ignore the '@' and
treat the rest of the string as the path to the SFTP remote's root.
Rclone will then add any relative subpaths automatically (including
unwrapping/decrypting remotes as necessary).
In other words, the path_override config parameter can now be used to
specify the difference between the SSH and SFTP paths. Once specified
in the config, it is no longer necessary to re-specify for each
command.

This allows using an external ssh binary instead of the built in ssh
library for making SFTP connections.
This makes another integration test target TestSFTPRcloneSSH:
Fixes#7012
Some changes about test cases:
Because MiddlewareCORS will return early on OPTIONS request,
this middleware should only be used once at NewServer function.
Test cases should pass AllowOrigin config instead of adding
this middleware again.
A new test case was added to test CORS preflight request with
an authenticator. Preflight request should always return 200 OK
regardless of autentications.

Before this change we released the ssh connection back to the pool
before the upload was finished.
This meant that uploads were re-using the same ssh connection which
reduces throughput.
This releases the ssh connection back to the pool only after the
upload has finished, or on error state.

This changes hasVirtual to an atomic struct variable that's updated on
add or delete from the virtual map.
This keeps it up to date and avoids deadlocks.

smb2.File implements the WriterAtCloser interface defined in
fs/types.go. Expose it via a OpenWriterAt method on
the fs struct to support multi-threaded writes.
As suddenly many people move to Box - another "unlimited" cloud story migration saga there are frequent questions about crypt files encoding to be used.
Box is base32768 friendly.
It has been tested with:
https://pub.rclone.org/base32768.zip
and:
rclone test info --check-length boxremote:
maxFileLength = 255 // for 1 byte unicode characters
maxFileLength = 255 // for 2 byte unicode characters
maxFileLength = 255 // for 3 byte unicode characters
maxFileLength = -1 // for 4 byte unicode characters
