4a33370072 backend: Fix unreliable TestListCancel/Timeout test
The test uses `WithTimeout` to create a context that cancels the List
operation after a given delay. Several backends internally use a derived
child context created using WithCancel.

The cancellation of a context first closes the done channel of the
context (here: the `WithTimeout` context) and _afterwards_ propagates
the cancellation to child contexts (here: the `WithCancel` context).
Therefor if the List implementation uses a child context, then it may
take a moment until that context is also cancelled. Thus give the
context cancellation a moment to propagate.

307aeb6849 rest: Don't return error if listing non-existent directory
When transferring a repository from S3 to, for example, a local disk
then all empty folders will be missing.

When saving files, the missing intermediate folders are created
automatically. Therefore, missing directories can be ignored by the
`List()` operation.

f903db492c backend: let ParseConfig return a Config pointer
In order to change the backend initialization in `global.go` to be able
to generically call cfg.ApplyEnvironment() for supported backends, the
`interface{}` returned by `ParseConfig` must contain a pointer to the
configuration.

An alternative would be to use reflection to convert the type from
`interface{}(Config)` to `interface{}(*Config)` (from value to pointer
type). However, this would just complicate the type mess further.

51dc80be5b backend: Use IoctlSetPointerInt for tcsetpgrp
This function casts its argument to int32 before passing it to the
system call, so that big-endian CPUs read the lower rather than the
upper 32 bits of the pid.

This also gets rid of the last import of "unsafe" in the Unix build.
I changed syscall to x/sys/unix while I was at it, to remove one more
import line. The constants and types there are aliases for their syscall
counterparts.

8e1e3844aa backend: factor out connection limiting and parameter validation
The SemaphoreBackend now uniformly enforces the limit of concurrent
backend operations. In addition, it unifies the parameter validation.

The List() methods no longer uses a semaphore. Restic already never runs
multiple list operations in parallel.

By managing the semaphore in a wrapper backend, the sections that hold a
semaphore token grow slightly. However, the main bottleneck is IO, so
this shouldn't make much of a difference.

The key insight that enables the SemaphoreBackend is that all of the
complex semaphore handling in `openReader()` still happens within the
original call to `Load()`. Thus, getting and releasing the semaphore
tokens can be refactored to happen directly in `Load()`. This eliminates
the need for wrapping the reader in `openReader()` to release the token.

We now check for space that is not reserved for the root user on the

f3d964a8c1 rclone: treat "file already closed" as command startup error
Since #3940 the rclone backend returns the commands exit code if it
fails to start. The list of expected errors was missing the "file
already closed"-error which can occur if the http test request first
learns about the closed pipe to rclone before noticing the canceled
context.

Go internally makes sure that a file descriptor is unusable once it was
closed, thus this cannot have unintended side effects (like accidentally
reading from the wrong file due to a reused file descriptor).

1ccab95bc4 b2: Support file hiding instead of deleting them permanently
Automatically fall back to hiding files if not authorized to permanently
delete files. This allows using restic with an append-only application
key with B2.  Thus, an attacker cannot directly delete backups with the
API key used by restic.

To use this feature create an application key without the deleteFiles
capability. It is recommended to restrict the key to just one bucket.
For example using the b2 command line tool:

    b2 create-key --bucket <bucketName> <keyName> listBuckets,readFiles,writeFiles,listFiles

d4aadfa389 all: Drop ctxhttp
This package is no longer needed, since we can use the stdlib's
http.NewRequestWithContext.

backend/rclone already did, but it needed a different error check due to
a difference between net/http and ctxhttp.

Also, store the http.Client by value in the REST backend (changed to a
pointer when ctxhttp was introduced) and use errors.WithStack instead
of errors.Wrap where the message was no longer accurate. Errors from
http.NewRequestWithContext will start with "net/http" or "net/url", so
they're easy to identify.
