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)"

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.

- 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
to avoid `map_struct` which is actually unsafe because it
does not verify alignment constraints at all

And use it for fixed and dynamic index. Please note that this
changes checksums for fixed indexes, so restore older backups
will fails now (not backward compatible).
mostly copied from BufferedDynamicReadAt from proxmox-backup-client
but the reader is wrapped in an Arc in addition to the Mutex
we will use this for local access to a pxar behind a didx file

copy_nonoverlapping is basically a memcpy which can also be done
via copy_from_slice which is not unsafe
(copy_from_slice uses copy_nonoverlapping internally)

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.

proxmox::tools now has a Uuid module using the native
libuuid.
Adds build dependency: libuuid1 (which is a Pre-Depends of
util-linux, so always installed anyway).
Drops uuid + 16 more crate dependencies.

The writer.write_all() call accessed data marked as
undefined to valgrind. Note that we shouldn't write out
uninitialized memory for security reasons anyway.
(note that vec::undefined already did zero-initialize the
data, but also marked it as undefined for valgrind when
compiling with the valgrind feature)

The type was sized properly but the number was still wrong,
fixed this.
TODO! Once unions with non-Copy values are stable make this
a `union { full: [u8; 4096], data: TheActualHeader }`;

AFAICT we have no use for it anymore, its api entry points
are gone. If we do end up needing something from it, it's
still in the git history anyway. (And about two thirds of it
can be made much less awkward by utilizing async-await
anyway, so no love lost there...)
Moved the chunker back into src/backup/chunker.rs
