since converting from i64 epoch timestamp to DateTime is not always
possible. previously, passing invalid backup-time from client to server
(or vice-versa) panicked the corresponding tokio task. now we get proper
error messages including the invalid timestamp.

similar to the other fix, if we do not set the buffer size manually,
we get better performance for high latency connections
restore benchmark from f.gruenbicher:
no delay, without patch: ~50MB/s
no delay, with patch: ~50MB/s
25ms delay, without patch: ~11MB/s
25ms delay, with path: ~50MB/s
my own restore benchmark:
no delay, without patch: ~1.5GiB/s

25ms delay, without patch: 30MiB/s

by leaving the buffer sizes on default, we get much better tcp performance
for high latency links
throughput is still impacted by latency, but much less so when
leaving the sizes at default.
the disadvantage is slightly higher memory usage of the server

Before, there were mixed usages of "data store" and
"datastore" throughout the docs.
This improves consistency in the docs by using only

We need to update the atime of chunk files if they already exist,
otherwise a concurrently running GC could sweep them away.
This is protected with ChunkStore.mutex, so the fstat/unlink does not
race with touching.

The iterator of get_chunk_iterator is extended with a third parameter
indicating whether the current file is a chunk (false) or a .bad file
(true).
Count their sizes to the total of removed bytes, since it also frees
disk space.
.bad files are only deleted if the corresponding chunk exists, i.e. has
been rewritten. Otherwise we might delete data only marked bad because
of transient errors.
While at it, also clean up and use nix::unistd::unlinkat instead of
unsafe libc calls.

This ensures that following backups will always upload the chunk,
thereby replacing it with a correct version again.
Format for renaming is <digest>.<counter>.bad where <counter> is used if
a chunk is found to be bad again before a GC cleans it up.
Care has been taken to deliberately only rename a chunk in conditions
where it is guaranteed to be an error in the chunk itself. Otherwise a
broken index file could lead to an unwanted mass-rename of chunks.

a range from high to low in rust results in an empty range
(see std::ops::Range documentation)
so we need to generate the range from 0..data.len() and then reverse it
also, the task log contains a newline at the end, so we have to remove
that (should it exist)
