Running restic self-update --quiet no longer
prints "writing restic to /usr/local/bin/restic".
The only output printed with -q is failures or
"successfully updated restic to version 0.12.1"

fix test fail: changelog title can't end with `.`
shorten changelog title
After the refactoring status updates were no longer printed in quiet
mode or when the output is not an interactive terminal. However, the
JSON output is often piped to e.g. another program. Thus, don't set the
update frequency to 0 in that case. The status updates are still
disabled for backup --quiet.
This also reduces the status update frequency to 60fps compared to a
potentially much higher value before the refactoring.
* PrintProgress no longer does unnecessary Sprintf calls, and performs
fewer allocations in general
* newProgressMax's callback checks whether the terminal supports
line updates once instead of once per call
* the callback looks up the terminal width once per call instead of
twice (on Windows)
* the status shortening now uses the Unicode-aware version from
internal/ui/termstatus (future-proofing)
This can be used to check how large a backup is or validate exclusions.
It does not actually write any data to the underlying backend. This is
implemented as a simple overlay backend that accepts writes without
forwarding them, passes through reads, and generally does the minimal
necessary to pretend that progress is actually happening.

Allow keeping hourly/daily/weekly/monthly/yearly snapshots for a given time period.
This adds the following flags/parameters to restic forget:
--keep-within-hourly duration
--keep-within-daily duration
--keep-within-weekly duration
--keep-within-monthly duration
--keep-within-yearly duration
Includes following changes:
- Add tests for --keep-within-hourly (and friends)
- Add documentation for --keep-within-hourly (and friends)
- Add changelog for --keep-within-hourly (and friends)
If a pack file is missing try to determine the contained pack ids based
on the repository index. This helps with assessing the damage to a
repository before running `rebuild-index`.
Just passing the list of blobs to packsToBlobs would also work in most
cases, however, it could cause unexpected results when multiple pack
files have the same prefix. Forget found prefixes to prevent this.
Apparently readahead was disabled by default. Enable readahead with the
Linux default size of 128kB. Larger values seem to have no effect.
This can speed up reading from the fuse mount by at least factor 5.
Speedup for a 1G random file stored in a local repository:
