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.

75de30cfa8 sync: fix --cutoff-mode soft & cautious so it doesn't end the transfer early 
Before ths fix --cutoff-mode soft and cautious would emit a Fatal
error which stopped the sync immediately.

This fix introduces a new error which is checked in the sync error
processing which stops the sync gracefully.

Fixes #4576

f5439ddc54 accounting: fix deadlock in stats printing 
The deadlock was caused in transfermap.go by calling mu.RLock() in one
function then calling it again in a sub function. Normally this is
fine, however this leaves a window where mu.Lock() can be called. When
mu.Lock() is called it doesn't allow the second mu.RLock() and
deadlocks.

    Thead 1                    Thread 2
    String():mu.RLock()
                               del():mu.Lock()
    sortedSlice():mu.RLock()                     - DEADLOCK

Lesson learnt: don't try using locks recursively ever!

This patch fixes the problem by removing the second mu.RLock(). This
was done by factoring the code that was calling it into the
transfermap.go file so all the locking can be seen at once which was
ultimately the cause of the problem - the code which used the locks
was too far away from the rest of the code using the lock.

This problem was introduced in:

10a6a92e52 accounting: reset bytes read during copy retry - fixes #4178 
During a copy/sync command, if an operation fails due to a network
issue and is retried, the underlying io.Reader is re-initialised,
but the stats for bytes already read are not reset, leading to incorrect
stats. THis was fixed by resetting the bytes read when an Account is
re-initialized.

6d0063d685 operations: Make --max-transfer more accurate 
Before this change we checked the transfer was out of range only
before the Read call. This means that we returned all the data to the
reader before declaring an error. This means that some backends wrote
the file even though an error was returned.

This fix checks the transfer after the Read as well, and chops the
excess characters off the read data if we are over the limit so that
we don't ever deliver all the data.

This fixes the tests introduced as part of 6f1766dd9e and #2672
on backends other than local.

f14871caf7 accounting: Correct exitcode on Transfer Limit Exceeded flag. Fixes #3203 
Before this change the exit code for transfer limit exceeded was
incorrect. This was because the `resolveExitCode` function unwraps the
error thus reading the underlying error which is not the same as the
error it was comparing to (`ErrorMaxTransferLimitReached`).

This change fixes it by splitting the error definition in two so that
when the Fatal error is unwrapped we match against
`ErrorMaxTransferLimitReached` however when we return the error we
return `ErrorMaxTransferLimitReachedFatal`.

d46f8d0ae5 accounting: fix memory leak on retries operations 
Before this change if an operation was retried on operations.Copy and
the operation was large enough to use an async buffer then an async
buffer was leaked on the retry.  This leaked memory, a file handle and
a go routine.

After this change if Account.WithBuffer is called and there is already
a buffer, then a new one won't be allocated.

56544bb2fd accounting: fix file handle leak on errors - fixes #3547 
In 53a1a0e3ef we introduced a problem where if there was an
error on the file being transferred then the file was re-opened and
the old one wasn't closed.

This was partially fixed in bfbddab46b however this didn't
address the case of the old file being closed.

This is now fixed by
- marking the file as open again in UpdateReader
- moving the stopping the accounting machinery to a new method Done

4ba6532915 accounting: make stats response consistent 
core/stats can return two different schemas in 'transferring' field.
One is object with fields the other is just plain string.
This is confusing, unnecessary and makes defining response schema
more difficult. It also returns `lastError` as value which can be
rendered differently depending on source of error.

This change standardizes 'transferring' filed to always return
object but with reduced fields if they are not available.
Former string item is converted to {name:remote_name} object.

'lastError' is forced to be a string as in some cases it can be encoded
as an object.

5990573ccd accounting: fix layout of stats - fixes #2910 
This fixes several things wrong with the layout of the stats.

Transfers which haven't started are printed in the same format as
those which have so the stats with `--progress` don't show horrible
artifacts.

Checkers and transfers now get a ": checkers" and ": transfers" label
on the end of the stats line.  Transfers will have the transfer stats
when the transfer has started instead of this.

There was a bug in the routine which shortened the file names (it
always produces strings 1 too long).  This is now fixed with a test.

The formatting string was wrong with a fixed width of 45 - this is now
replaces with the value of `--stats-file-name-length`.

This also meant that there were unecessary leading spaces in the file
names.  So the default `--stats-file-name-length` was raised to 45
from 40.

de6ec8056f fs/accounting: fix moving average speed for file stats 
Before this change the moving average for the individual file stats

seconds.

This change starts the weighting period as 1 and moves it up once per
sample which gets the average to a better value instantly.

the same constant), without that feature.

d0d6b83a7a fs/accounting: rework to enable accounting to work with crypt and b2 
This removes the old system of part accounting and replaces it with a
system of popping off the accounting reader and wrapping up new ones
as necessary.

This makes it much easier to carry the context down the chain of
wrapped readers and get the limiting as near as possible to the
output.  This makes the accounting more accurate and the bandwidth
limiting smoother.
