Currently, the cmd/restic package contains a significant amount of code
that modifies repository internals. This code should in the mid-term
move into the repository package.
LoadBlobsFromPack is now part of the repository struct. This ensures
that users of that method don't have to deal will internals of the
repository implementation.
The filerestorer tests now also contain far fewer pack file
implementation details.
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
unlikely to be important
- find: filtered directories would be ignored. However, this
optimization missed that it is possible that two directories have the
exact same content. Such directories would be incorrectly ignored too.
Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```
Thus, remove the functionality as it's apparently too complex to use
correctly.
When using `RESTIC_REPOSITORY_FILE` in combination with `restic init`,
the repository is missing in the output:
```
$ restic init
created restic repository 3c872be20f at
[...]
```
This is due to the code using `gopts.Repo`, which is empty in this case.
This change better resembles the output generated by `Snapshot.String()`,
which includes both username and hostname.

This introduces a new modifier to the output of the diff command. It
appears whenever two files being compared only differ in their content
but not in their metadata. As far as we know, under normal
circumstances, this should only ever happen if some kind of bitrot has
happened in the source file. The prerequisite for this detection to work
is that the right-side snapshot of the comparison has been created with
"backup --force".
Adds
* snapshotMetadataArgs, which holds the new metadata as strings parsed from
the command line
* snapshotMetadata, which holds the new metadata converted to the
correct types
Bug #1681 suggests that restic should not be nice to user and should
refrain from creating a mountpoint if it does not exist. Nevertheless,
it currently opens the repository before checking for the mountpoint's
existence. In the case of large or remote repositories, this process
can be time-consuming, delaying the inevitable outcome.
/restic mount --repo=REMOTE --verbose /tmp/backup
repository 33f14e42 opened (version 2, compression level max)
[0:38] 100.00% 162 / 162 index files loaded
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory
real 0m39.534s
user 1m53.961s
sys 0m3.044s
In this scenario, 40 seconds could have been saved if the nonexistence
of the path had been verified beforehand.
This patch relocates the mountpoint check to the beginning of the
runMount function, preceding the opening of the repository.
/restic mount --repo=REMOTE --verbose /tmp/backup
Mountpoint /tmp/backup doesn't exist
stat /tmp/backup: no such file or directory

When using `RESTIC_REPOSITORY_FILE` in combination with `restic init`,
the repository is missing in the output:
```
$ restic init
created restic repository 3c872be20f at
[...]
```
This is due to the code using `gopts.Repo`, which is empty in this case.
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.
