Before this change if we copied files of unknown size, then they lost
their metadata.
This was particularly noticeable using --s3-decompress.
This change adds metadata to Rcat and RcatSized and changes Copy to
pass the metadata in when it calls Rcat for an unknown sized input.
Fixes#6546
Before this change, some files were giving this error when downloaded
from Cloudflare and other providers.
ERROR corrupted on transfer: sizes differ NNN vs MMM
This is because these providers auto gzips the object when rclone
wasn't expecting it to. (AWS does not gzip objects without their being
uploaded gzipped).
This patch adds a quirk to for fix the problem and a flag to control
it. The quirk `might_gzip` is set to `true` for all providers except
AWS.

Before this fix it was impossible to stop rclone generating an
X-Amx-Acl: header which is incompatible with GCS with uniform access
control and is generally deprecated at AWS.
The API endpoint GetBucketLocation requires
top level permission.
If we do an authenticated head request to a bucket, the bucket location will be returned in the HTTP headers.
Fixes#5066
Before this change if --user-server-modtime was in use the ModTime
could change for an object as we receive it accurate to the nearest ms
in listings, but only accurate to the nearest second in HEAD and GET
requests.
Normally AWS returns the milliseconds as .000 in listings, but if
versions are in use it may not. Storj S3 also seems to return
milliseconds.
This patch tries to keep the maximum precision in the last modified
time, so it doesn't update a last modified time with a truncated
version if the times were the same to the nearest second.

Before this change rclone used statx() to read the metadata for files
from the local filesystem when `-M` was in use.
Unfortunately statx() was only introduced in kernel 4.11 which was
released in April 2017 so there are current systems (eg Centos 7)
still on kernel versions which don't support statx().
This patch checks to see if statx() is available and if it isn't, it
falls back to using fstatat() which was introduced in Linux 2.6.16
which is guaranteed for all Go versions.

In https://github.com/jlaffaye/ftp/commit/212daf295f the upstream FTP
library changed the way adding your own dialer works which meant that
connections when using explicit FTP were failing.
This patch reworks our connection code to bring it into the
expectations of the library.
Before this fix, if an error ocurred reading the metadata, it could be
set as nil and then used, causing a crash.
This fix changes the readMetadata function so it returns an error, and
the error is always set if the metadata returned is nil.
If mkdir fails then before this change it would have thrown an
error.
After this change, if the error indicated that the directory
already exists then the error is not returned to the user.
This fixes a race condition when two rclone threads are trying to
create the same directory.

8d1fff9a82 local: obey file filters in listing to fix errors on excluded files
We started using filters in the local backend so the user could short
circuit troublesome files/directories at a low level.
However this caused a number of integration tests to fail. This turned
out to be in backends wrapping the local backend. For example the
combine backend test failed because it changes the paths passed to the
local backend so they no longer match the paths in the current filter.
To fix this, a new feature flag `FilterAware` was added and the
UseFilter context flag is only passed to backends which support it. As
the wrapping backends don't support the flag, this fixes the problems
in the integration tests.
In future the wrapping backends could modify the active filters to
match the path modifications and then they could set the FilterAware
flag.
