NOTE: This feature is not retro-active; it will not cater to previous transactions
on existing setups.
To enable this feature, please set ` _MINIO_DRIVE_QUORUM=on` environment
variable as part of systemd service or k8s configmap.
Once this has been enabled, you need to also set `list_quorum`.
```
~ mc admin config set alias/ api list_quorum=auto`
```
A new debugging tool is available to check for any missing counters.
Following extension allows users to specify immediate purge of
all versions as soon as the latest version of this object has
expired.
```
<LifecycleConfiguration>
<Rule>
<ID>ClassADocRule</ID>
<Filter>
<Prefix>classA/</Prefix>
</Filter>
<Status>Enabled</Status>
<Expiration>
<Days>3650</Days>
<ExpiredObjectAllVersions>true</ExpiredObjectAllVersions>

Will combine or write partial data of each version found in the inspect data.
Example:
```
> xl-meta -export -combine inspect-data.1228fb52.zip
(... metadata json...)
}

Attempting to reconstruct using parity sets:
* Setup: Data shards: 9 - Parity blocks: 6
Have 6 complete remapped data shards and 6 complete parity shards. Could NOT reconstruct: too few shards given
* Setup: Data shards: 8 - Parity blocks: 5
Have 5 complete remapped data shards and 5 complete parity shards. Could reconstruct completely
0 bytes missing. Truncating 0 from the end.
Wrote output to 994f1113-da94-4be1-8551-9dbc54b204bc.complete
```
So far only inline data, but no real reason that external data can't also be included with some handling of blocks.
Supports only unencrypted data.
data shards were wrong due to a healing bug
reported in #13803 mainly with unaligned object
sizes.
This PR is an attempt to automatically avoid
these shards, with available information about
the `xl.meta` and actually disk mtime.
Existing:
```go
type xlMetaV2 struct {
Versions []xlMetaV2Version `json:"Versions" msg:"Versions"`
}
```
Serialized as regular MessagePack.
```go
//msgp:tuple xlMetaV2VersionHeader
type xlMetaV2VersionHeader struct {
VersionID [16]byte
ModTime int64
Type VersionType
Flags xlFlags
}
```
Serialize as streaming MessagePack, format:
```
int(headerVersion)
int(xlmetaVersion)
int(nVersions)
for each version {
binary blob, xlMetaV2VersionHeader, serialized
binary blob, xlMetaV2Version, serialized.
}
```
xlMetaV2VersionHeader is <= 30 bytes serialized. Deserialized struct
can easily be reused and does not contain pointers, so efficient as a
slice (single allocation)
This allows quickly parsing everything as slices of bytes (no copy).
Versions are always *saved* sorted by modTime, newest *first*.
No more need to sort on load.
* Allows checking if a version exists.
* Allows reading single version without unmarshal all.
* Allows reading latest version of type without unmarshal all.
* Allows reading latest version without unmarshal of all.
* Allows checking if the latest is deleteMarker by reading first entry.
* Allows adding/updating/deleting a version with only header deserialization.
* Reduces allocations on conversion to FileInfo(s).
- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

The key is included in the response but can be separated so zip
and the key doesn't have to be sent on the same channel.
