79c9bf55b9 backup/{dynamic, fixed}_index: improve error message for small index files
index files that were smaller than their respective header size,
would fail with

"failed to fill whole buffer"

instead now check explicitely for the size and fail with
"index too small (size)"

fe0efb25e8 backup: index readers: drop useless shared lock
This is only acquired in those two methods, both as shared. So it has
no use.

It seems, that it was planned in the past that the index deletion
should take the exclusive, while read and write takes the shared
flock on the index, as one can guess from the lock comments in commit
0465218953

But then later, in commit c8ec450e37)
the documented semantics where changed to use a temp file and do an
atomic rename instead for atomicity.

The reader shared flock on the index file was done inbetween,
probably as preparatory step, but was not removed again when strategy
was changed to using the file rename instead.

Do so now, to avoid confusion of readers and a useless flock.

6a7be83efe avoid chrono dependency, depend on proxmox 0.3.8
- remove chrono dependency

- depend on proxmox 0.3.8

- remove epoch_now, epoch_now_u64 and epoch_now_f64

- remove tm_editor (moved to proxmox crate)

- use new helpers from proxmox 0.3.8
  * epoch_i64 and epoch_f64
  * parse_rfc3339
  * epoch_to_rfc3339_utc
  * strftime_local

- BackupDir changes:
  * store epoch and rfc3339 string instead of DateTime
  * backup_time_to_string now return a Result
  * remove unnecessary TryFrom<(BackupGroup, i64)> for BackupDir

- DynamicIndexHeader: change ctime to i64

- FixedIndexHeader: change ctime to i64

833eca6d2f use non-panicky timestamp_opt where appropriate
by either printing the original, out-of-range timestamp as-is, or
bailing with a proper error message instead of panicking.

2e079b8bf2 partially revert commit 1f82f9b7b5
do it backwards compatible. Also, code was wrong because FixedIndexWriter

1f82f9b7b5 src/backup/index.rs: add compute_csum
And use it for fixed and dynamic index. Please note that this
changes checksums for fixed indexes, so restore older backups

facd9801cf add incremental backup support
To support incremental backups (where not all chunks are sent to the
server), a new parameter "reuse-csum" is introduced on the
"create_fixed_index" API call. When set and equal to last backups'
checksum, the backup writer clones the data from the last index of this
archive file, and only updates chunks it actually receives.

In incremental mode some checks usually done on closing an index cannot
be made, since they would be inaccurate.

a95a3fb893 fix csum calculation of not 'chunk_size' aligned images
the last chunk does not have to be as big as the chunk_size,
just use the already available 'chunk_end' function which does the
correct thing

this fixes restoration of images whose sizes are not a multiple of
'chunk_size' as well

9ea4bce444 bump proxmox crate to 0.1.7
The -sys, -tools and -api crate have now been merged into
the proxmx crate directly. Only macro crates are separate
(but still reexported by the proxmox crate in their
designated locations).

When we need to depend on "parts" of the crate later on
we'll just have to use features.

The reason is mostly that these modules had
inter-dependencies which really make them not independent
enough to be their own crates.
