7881309d63 backend: move backend implementation helpers to util package
This removes code that is only used within a backend implementation from
the backend package. The latter now only contains code that also has
external users.

50e0d5e6b5 backend: Hardcode backend scheme in Factory

7d12c29286 backend: Unify backend construction using factory and registry
This unified construction removes most backend-specific code from

use custom backends if necessary.

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.

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.

40ac678252 backend: remove Test method
The Test method was only used in exactly one place, namely when trying
to create a new repository it was used to check whether a config file
already exists.

Use a combination of Stat() and IsNotExist() instead.

ff7ef5007e Replace most usages of ioutil with the underlying function
The ioutil functions are deprecated since Go 1.17 and only wrap another
library function. Thus directly call the underlying function.

This commit only mechanically replaces the function calls.

9aa2eff384 Add plumbing to calculate backend specific file hash for upload
This enables the backends to request the calculation of a
backend-specific hash. For the currently supported backends this will
always be MD5. The hash calculation happens as early as possible, for
pack files this is during assembly of the pack file. That way the hash
would even capture corruptions of the temporary pack file on disk.

e5f0f67ba0 Modernize error handling in local backend
* Stop prepending the operation name: it's already part of os.PathError,
  leading to repetitive errors like "Chmod: chmod /foo/bar: operation not
  permitted".

* Use errors.Is to check for specific errors.

c73316a111 backends: add sanity check for the uploaded file size
Bugs in the error handling while uploading a file to the backend could
cause incomplete files, e.g. https://github.com/golang/go/issues/42400
which could affect the local backend.

Proactively add sanity checks which will treat an upload as failed if
the reported upload size does not match the actual file size.

a2d4209322 Don't recurse in local backend's List if not required
Due to the return if !isFile, the IsDir branch in List was never taken
and subdirectories were traversed recursively.

Also replaced isFile by an IsRegular check, which has been equivalent
since Go 1.12 (golang/go@a2a3dd00c9).

40ee17167e local: Ignore permission errors on chmod call in Save/Remove operation
The file is already created with the proper permissions, thus the chmod
call is not critical. However, some file systems have don't allow
modifications of the file permissions. Similarly the chmod call in the Remove
operation should not prevent it from working.
