for encrypted chunks this is currently not possible, as we need the key
to decode the chunk.

regular chunks are only decoded when their contents are accessed, in
which case we need to have the key anyway and want to verify the digest.
for blobs we need to verify beforehand, since their checksums are always
calculated based on their raw content, and stored in the manifest.
manifests are also stored as blobs, but don't have a digest in the
traditional sense (they might have a signature covering parts of their
contents, but that is verified already when loading the manifest).
this commit does not cover pull/sync code which copies blobs and chunks
as-is without decoding them.

To prevent a race with a background GC operation, do not allow deletion
of backups who's index might currently be referenced as the "known chunk
list" for successive backups. Otherwise the GC could delete chunks it
thinks are no longer referenced, while at the same time telling the
client that it doesn't need to upload said chunks because they already
exist.
Additionally, prevent deletion of whole backup groups, if there are
snapshots contained that appear to be currently in-progress. This is
currently unlikely to trigger, as that function is only used for sync
jobs, but it's a useful safeguard either way.
Deleting a single snapshot has a 'force' parameter, which is necessary
to allow deleting incomplete snapshots on an aborted backup. Pruning
also sets force=true to avoid the check, since it calculates which
snapshots to keep on its own.
To avoid code duplication, the is_finished method is factored out.

And make verify_crc private for now. We always call load_from_reader() to
verify the CRC.
Also add load_chunk() to datastore.rs (from chunk_store::read_chunk())
using micros vs. as_secs_f64 allows to have it calculated as usize
bytes, easier to handle - this was also used when it still lived in
upload_chunk_info_stream

Verbosity needs to be a non binary level, as this now is just
debug/development info, for endusers normally to much.
We want to have it available, but with a much higher verbosity level.

Track reused size and chunk counts.
Log reused size and use pretty print for all sizes and bandwidth
metrics.
Calculate speed over the actually uploaded size, as else it can be
skewed really bad (showing like terabytes per second)

This also replaces the recently introduced --encryption
parameter on the client with a --crypt-mode parameter.
This can be "none", "encrypt" or "sign-only".
Note that this introduces various changes in the API types
which previously did not take the above distinction into
account properly:
Both `BackupContent` and the manifest's `FileInfo`:
lose `encryption: Option<bool>`
gain `crypt_mode: Option<CryptMode>`
Within the backup manifest itself, the "crypt-mode" property
will always be set.

The download methods used to take the destination by value

The repo URL consists of
* optional userid
* optional host
* datastore name
All three have defined regex or format, but none of that is used, so
for example not all valid datastore names are accepted.
Move definition of the regex over to api2::types where we can access
all required regexes easily.

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.

Limit the total number of entries and therefore the approximate memory
consumption instead of doing this on a per directory basis as it was previously.
This makes more sense as it limits not only the width but also the depth of the
directory tree.
Further, instead of hardcoding this value, allow to pass this information as
additional optional parameter 'entires-max'.
By this, creation of the archive with directories containing a large number of
entries is possible.

And use an extra functzion set_callback() to configure that.
Also rewrite pxar/fuse.rs and implement a generic Session (will get
further cleanups with next patches).
This exposes the option to pass a list of exclude MatchPattern via the
'--exclude' option.
The list is encoded as file '.pxarexclude-cli' in the archives root directory.
If such a file is present in the filesystem, it is skipped and not included in
the archive in order to avoid conflicting information.
