The behavior of the new option should reflect the behavior of normal backups: when the command exit code is zero and there is no output in the stdout, emit a warning but create the snapshot. This commit fixes the integration tests and the ReadCloserCommand struct.
Return with an error containing the stderr of the given command in case it fails. No new snapshot will be created and future prune operations on the repository will remove the unreferenced data.

In order to determine whether to save a snapshot, we need to capture the exit code returned by a command. In order to provide a nice error message, we supply stderr as well.

It acts similar to --stdin but reads its data from the stdout of the given command instead of os.Stdin.

In order to run with --stdin-from-command we need to short-circuit some functions similar to how it is handled for the --stdin flag. The only difference here is that --stdin-from-command actually expects that len(args) should be greater 0 whereas --stdin does not expect any args at all.

This new flag is added to the backup subcommand in order to allow restic to control the execution of a command and determine whether to save a snapshot if the given command succeeds.

inodes are only unique within a device. Use the HardlinkIndex from the
restorer instead of the custom (broken) hashmap to correctly account for
both inode and deviceID.
Go 1.21 has switched the default from GOARM=5 to GOARM=7. So far there
have been complaints from Raspberry Pi 1 users, as the first raspberry
pi version only supports ARMv6. Exclude older ARM versions as these are
likely not relevant (rest-server also only supports ARMv6/7) and enforce
the use of software floating point emulation.
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.
