NCDU (NCurses Disk Usage) is a tool to analyse disk usage of directories.
It has an option to save a directory tree and analyse it later.
This patch adds an output option to the ls command.
A snapshot can be seen with
`restic ls latest --ncdu | ncdu -f -`

The method is not available on the restic.Repository interface that is
used for testing. Drop the call as a small amount of additional index
writes is not a problem.
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.
`writeStatus` also cleans no longer used status lines.
The old code actually cleaned one line too much. However, as that line
was never used it makes no difference.
If a lock could not be loaded, then restic would check all lock files
again. These repeated checks are not useful as the status of a lock file
cannot change unless its ID changes too. Thus, skip already check lock
files on retries.
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.
To only stream the content of a pack file once, check used StreamPack
with a custom pack load function. This combination was always brittle
and complicates using StreamPack everywhere else. Now that StreamPack
internally uses PackBlobIterator use that primitive instead, which is a
much better fit for what the check command requires.
If client.Do returns an error, then there's no body that has to be
closed. For requests for which we are not interested in the response
body, immediately drain and close the body to make sure it isn't
forgotten later on.
This change in particular adds the missing `Close()` call for the
`List()` command.
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.
