bd787e8f45 filter: Fix incorrect filtering with UseFilter context flag and wrapping backends 
In this commit

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.

See #6376

da404dc0f2 sync,copy: Fix --fast-list --create-empty-src-dirs and --exclude 
Before this change, if --fast-list was in use while doing a sync or
copy with --create-empty-src-dirs and --exclude excluded all the files
from the directory (but not the directory), then the directory would
not be created.

This is also visible with `rclone tree` which uses the same tree
building approach as `rclone sync --fast-list` where the directories
would go missing from the tree view.

This was caused by not adding the parents of excluded files to the
directory tree.

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.

a2545066e2 drive: constrain list by filter #5023 
Google Drive API allows for clauses like "modifiedTime > '2012-06-04T12:00:00'"
in the query param, so the filter flags --max-age and --min-age can be applied
directly at the directory listing phase rather than in a filter.
This is extremely helpful when we want to do an incremental backup of a remote
drive with many files but the number of recently changed file is small.

2e21c58e6a fs: deglobalise the config #4685 
This is done by making fs.Config private and attaching it to the
context instead.

The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.

75a6c49f87 Fix error counter - fixes #3650 
For few commands, RClone counts a error multiple times. This was fixed by
creating a new error type which keeps a flag to remember if the error has
already been counted or not. The CountError function now wraps the original
error eith the above new error type and returns it.

af05e290cf Fix --files-from without --no-traverse doing a recursive scan 
In a28239f005 we made --files-from obey --no-traverse.  In the
process this caused --files-from without --no-traverse to do a
complete recursive scan unecessarily.

This was only noticeable in users of fs/march, so sync/copy/move/etc
not in ls/lsf/etc.

This fix makes sure that we use conventional directory listings in
fs/march unless `--files-from` and `--no-traverse` is set or
`--fast-list` is active.

Fixes #3619

6c38bddf3e walk: fix listing with filters listing whole remote 
Prior to this fix, a request such as

    rclone lsf -R --include "/dir/**" remote:

Would use ListR which is very inefficient as it lists the whole remote
for one directory.

This changes it to use recursive walking if the filters imply any
directory filtering.  So `--include *.jpg` and `--exclude *.jpg` will
still use ListR wheras `--include "/dir/**` will not.

f78cd1e043 Add context propagation to rclone 
- Change rclone/fs interfaces to accept context.Context
- Update interface implementations to use context.Context
- Change top level usage to propagate context to lover level functions

Context propagation is needed for stopping transfers and passing other
request-scoped values.

a28239f005 filter: Make --files-from traverse as before unless --no-traverse is set 
In c5ac96e9e7 we made --files-from only read the objects specified and
don't scan directories.

This caused problems with Google drive (very very slow) and B2
(excessive API consumption) so it was decided to make the old
behaviour (traversing the directories) the default with --files-from
and use the existing --no-traverse flag (which has exactly the right
semantics) to enable the new non scanning behaviour.

See: https://forum.rclone.org/t/using-files-from-with-drive-hammers-the-api/8726

efd720b533 walk: Implement walk.ListR which will use ListR if at all possible 
It otherwise has the nearly the same interface as walk.Walk which it
will fall back to if it can't use ListR.

Using walk.ListR will speed up file system operations by default and
use much less memory and start immediately compared to if --fast-list
had been supplied.

c5ac96e9e7 Make --files-from only read the objects specified and don't scan directories 
Before this change using --files-from would scan all the directories
that the files could possibly be in causing rclone to do more work
that was necessary.

After this change, rclone constructs an in memory tree using the
--fast-list mechanism but from all of the files in the --files-from
list and without scanning any directories.

Any objects that are not found in the --files-from list are ignored
silently.

This mechanism is used for sync/copy/move (march) and all of the
listing commands ls/lsf/md5sum/etc (walk).

11da2a6c9b Break the fs package up into smaller parts. 
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.
