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.

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.

421585dd72 accounting: add context to Account and propagate changes #3257
This is preparation for getting the Accounting to check the context,
buf first we need to get it in place. Since this is one of those
changes that makes lots of noise, this is in a seperate commit.

3de9bd9d04 vfs: fix hang in read wait code - Fixes #4039
Before this fix, rclone would sometimes hang in vfs.readAt().

This was due to a race condition causing rclone to miss the timeout
signal.

This was fixed by a small amount of extra locking.

This very likely also fixes a number of "failed to wait for
in-sequence read" errors.

1a8c5708c5 vfs: ignore file not found errors from Hash in Read.Release
There is nothing we can do about this at this point and this error can
happen when moving files so we ignore it to clean the logs up.

5beeac7959 vfs: make ReadAt for non cached files work better with non-sequential reads
This makes ReadAt for non cached files wait a short time (up to 5mS)
if it gets an out of order read (which would normally cause a seek and
which take a long time) to see if the gap will be filled with an in
order read.

This makes mount2 based on go-fuse work more efficiently and enables
async reading in normal mount.

A similar change was done for WriteAt in af030f74f5

ba121eddf0 vfs: make objects of unknown size readable through the VFS
These objects (eg Google Docs) appear with 0 length in the VFS.

Before this change, these only read 0 bytes.

After this change, even though the size appears to be 0, the objects
can be read to the end.  If the objects are read to the end then the
size on the handle will be updated.

8243ff8bc8 accounting: isolate stats to groups
Introduce stats groups that will isolate accounting for logically
different transferring operations. That way multiple accounting
operations can be done in parallel without interfering with each other
stats.

Using groups is optional. There is dedicated global stats that will be
used by default if no group is specified. This is operating mode for CLI
usage which is just fire and forget operation.

For running rclone as rc http server each request will create it's own
group. Also there is an option to specify your own group.

be0464f5f1 accounting: change stats interface
This is done to make clear ownership over accounting object and prepare
for removing global stats object.

Stats elapsed time calculation has been altered to account for actual
transfer time instead of stats creation time.

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.

44276db454 vfs: make -ve sized files appear as 0 size. #320
This means that Google docs will no longer appear as huge files in
`rclone mount`.  They will not be downloadable, though sometimes
trying twice will work.

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.
