Before this change, bisync proactively converted modtime precision when greater
than what the destination backend supported.
This dates back to a time before bisync considered the modifyWindow for same-side
comparisons. Back then, it was problematic to save a listing with 12:54:49.7 for
a backend that can't handle that precision, as on the next run the backend would
report the time as 12:54:50 and bisync would think the file had changed. So the
truncation was a workaround to anticipate this and proactively record the time
with the precision we expect to receive next time.
However, this caused problems for backends (such as dropbox) that round instead
of truncating as bisync expected.
After this change, bisync preserves the original precision in the listing
(without conversion), even when greater than what the backend supports, to avoid
rounding error. On the next run, bisync will compare it to the rounded time
reported by the backend, and if it's within the modifyWindow, it will treat them
as equivalent.
This adds a new optional parameter to the backend, to specify a path
to a unix domain socket to connect to, instead the specified URL.
The URL itself is still used for the rest of the HTTP client, allowing
host and subpath to stay intact.
This allows using rclone with the webdav backend to connect to a WebDAV
server provided at a Unix Domain socket:
rclone serve webdav --addr unix:///tmp/my.socket remote:path
rclone --webdav-unix-socket /tmp/my.socket --webdav-url http://localhost lsf :webdav:
Cloudflare will normally automatically decompress files with
`Content-Encoding: gzip` when downloaded. This is not what AWS S3 does
and it breaks the integration tests.
This fudges the integration tests to upload the test file with
`Cache-Control: no-transform` on Cloudflare R2 and puts a note in the
docs about this problem.

- `--s3-sts-endpoint` is no longer supported
- `--s3-use-unsigned-payload` to control use of trailer checksums (needed for non AWS)
