This change checks the context whenever rclone might retry, and
doesn't retry if the current context has an error.
This fixes the pathological behaviour of `--max-duration` refusing to
exit because all the context deadline exceeded errors were being
retried.
This unfortunately meant changing the shouldRetry logic in every
backend and doing a lot of context propagation.

Sharepoint 2016 returns status 204 to the purge request
even if the directory to purge does not really exist.
This change adds an extra check to detect this condition
and returns a proper error code.
The go-ntlmssp NTLM negotiator has to try various authentication methods.
Intermediate responses from Sharepoint have status code 401, only the
final one is different. When rclone runs a large operation in parallel
goroutines according to --checkers or --transfers, one of threads can
receive intermediate 401 response targeted for another one and returns
the 401 authentication error to the user.
This patch fixes that.
On-premises Sharepoint returns HTTP errors 400 or 500 in
reply to attempts to use file names with special characters
like hash, percent, tilde, invalid UTF-7 and so on.
This patch activates transparent encoding of such characters.
As per Microsoft documentation, Windows authentication
(NTLM/Kerberos/Negotiate) is not supported with HTTP/2.
This patch disables transparent HTTP/2 support when the
vendor setting is "sharepoint-ntlm". Otherwise connections
to IIS/10.0 can fail with HTTP_1_1_REQUIRED.

The most popular keyword for the Sharepoint in-house or company
installations is "On-Premises".
"Microsoft OneDrive account" is in fact just a Microsoft account.

Add new option option "sharepoint-ntlm" for the vendor setting.
Use it when your hosted Sharepoint is not tied to the OneDrive
accounts and uses NTLM authentication.
Also add documentation and integration test.
Fixes: #2171
Before this change the webdav backend didn't truncate Range requests
to the size of the object. Most webdav providers are OK with this (it
is RFC compliant), but it causes 4shared to return 500 internal error.
Because Range requests are used in mounting, this meant that mounting
didn't work for 4shared.
This change truncates the Range request to the size of the object.

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.
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
- add a directory to the optional Purge interface
- fix up all the backends
- add an additional integration test to test for the feature
- use the new feature in operations.Purge
Many of the backends had been prepared in advance for this so the
change was trivial for them.
When we run MKCOL on 4shared on a directory that already exists, this
returns a 409/Conflict error. However this error code usually means
that the intermediate collections need creating.
The actual error code to return when trying to create a directory that
already exists isn't specified in the RFC, only that an error MUST be
returned and there are already 3 statuses checked in the code.
However using 409 makes rclone's usual strategy for making directories
fail and return the 409 error.
This patch tries the MKCOL and if it returns an unrecognised error
code, then calls PROPFIND on the directory to discover whether the
directory really exists or not.
This should also cover other WebDAV servers returning other error
messages we haven't accounted for in the code yet.
Before this change if the server sent us xml like this
```
<D:propstat>
<D:prop>
<g0:quota-available-bytes/>
<g0:quota-used-bytes/>
</D:prop>
<D:status>HTTP/1.1 404 Not Found</D:status>
</D:propstat>
```
Rclone would read the empty XML items as containing 0
After this fix we make sure that we have a value before using it.
Before this change rclone used "Authorization: BEARER token". However
according the the RFC this should be "Bearer"
https://tools.ietf.org/html/rfc6750#section-2.1
This changes it to "Authorization: Bearer token"
Fixes#3751 and interop with Salesforce Webdav server
When using nextcloud, before this change we only uploaded one of SHA1
or MD5 checksum in the OC-Checksum header with preference to SHA1 if
both were set.
This makes the MD5 checksums read as empty string which makes syncing
with checksums less useful than they should be as all the MD5
checksums are blank.
This change makes it so that we only upload the SHA1 to nextcloud.
The behaviour of owncloud is unchanged as owncloud uses the checksum
as an upload integrity check only and calculates its own checksums.
See: https://forum.rclone.org/t/how-to-specify-hash-method-to-checksum/13055
- 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.
Some WebDAV servers return an empty Available and Used which parses as 0.
This caused About to return the Total as 0 which can confused mounted
file systems.
After this change we ignore the result if Available and Used are both 0.

Before this change a race condition existed in mkdir
- the directory was attempted to be created
- the parent didn't exist so it failed
- the parent was created
- the directory was created again
The last step failed as the directory was created in a different thread.
This was fixed by checking the error messages of MKCOL for both
directory creations, rather than only the first.
Make the pacer package more flexible by extracting the pace calculation
functions into a separate interface. This also allows to move features
that require the fs package like logging and custom errors into the fs
package.
Also add a RetryAfterError sentinel error that can be used to signal a
desired retry time to the Calculator.
Bitrix Site Manager emits `<D:resourcetype><collection/></D:resourcetype>`
missing the namespace on the `collection` tag. This causes the item
to be identified as a file instead of a directory.
To work around this look at the Microsoft extension prop
`iscollection` which seems to be emitted as well.
The time format provided by webdav servers seems to vary wildly from
that specified in the RFC - rclone already parses times in 5 different
formats!
If an unparseable time is found, then fail softly logging an ERROR
(just once) but returning the epoch.
This will mean that webdav servers with bad time formats will still be
usable by rclone.
