site replication: fix healing of bucket deletes. (#15377)
This PR changes the handling of bucket deletes for site 
replicated setups to hold on to deleted bucket state until 
it syncs to all the clusters participating in site replication.

fix: readQuorum calculation when defaultParityCount is 0 (#15363)
when parity is '0' the readQuorum must be equal
to the number of data disks.

Independent Multipart Uploads (#15346)
Do completely independent multipart uploads.

In distributed mode, a lock was held to merge each multipart 
upload as it was added. This lock was highly contested and 
retries are expensive (timewise) in distributed mode.

Instead, each part adds its metadata information uniquely. 
This eliminates the per object lock required for each to merge.
The metadata is read back and merged by "CompleteMultipartUpload" 
without locks when constructing final object.

heal: Report correctly in multip-pools setup (#15117)
`mc admin heal -r <alias>` in a multi setup pools returns incorrectly
grey objects. The reason is that erasure-server-pools.HealObject() runs
HealObject in all pools and returns the result of the first nil
error. However, in the lower erasureObject level, HealObject() returns
nil if an object does not exist + missing error in each disk of the object
in that pool, therefore confusing mc.

Make erasureObject.HealObject() to return not found error in the lower
level, so at least erasureServerPools will know what pools to ignore.

heal: Re-heal an object when a corruption is found during normal scan (#14482)
When scanning using normal mode, HealObject() can report an 
error saying that it found a corrupted part. This doesn't have 
when HealObject() is called with bitrot scan flag. However, when 
this happens, we can still restart HealObject() with the bitrot scan.

This is also important because this means the scanner and the 
new disks healer will not be able to heal an object that doesn't 
exist in a specific disk and has corruption in another disk.

Also without this PR, mc admin heal command without bitrot will report
an error.

fix: allow danging objects to be purged properly deleteMultipleObjects() (#14273)
Deleting bulk objects had an issue since the relevant versionID
is not passed through the layers to ensure that the dangling
object purge actually works cleanly.

This is a continuation of quorum related error returned by
multi-object delete API from #14248

This PR ensures that we pass down correct information as
well as extend the scope of dangling object detection.

heal: isObjectDangling should return false when it cannot decide (#14053)
In a multi-pool setup when disks are coming up, or in a single pool
setup let's say with 100's of erasure sets with a slow network.

It's possible when healing is attempted on `.minio.sys/config`
folder, it can lead to healing unexpectedly deleting some policy
files as dangling due to a mistake in understanding when `isObjectDangling`
is considered to be 'true'.

This issue happened in commit 30135eed86
when we assumed the validMeta with empty ErasureInfo is considered
to be fully dangling. This implementation issue gets exposed when
the server is starting up.

This is most easily seen with multiple-pool setups because of the
disconnected fashion pools that come up. The decision to purge the
object as dangling is taken incorrectly prior to the correct state
being achieved on each pool, when the corresponding drive let's say
returns 'errDiskNotFound', a 'delete' is triggered. At this point,
the 'drive' comes online because this is part of the startup sequence
as drives can come online lazily.

This kind of situation exists because we allow (totalDisks/2) number
of drives to be online when the server is being restarted.

Implementation made an incorrect assumption here leading to policies
getting deleted.

Added tests to capture the implementation requirements.

correctly calculate read quorum based on the available fileInfo (#14000)
The current usage of assuming `default` parity of `4` is not correct
for all objects stored on MinIO, objects in .minio.sys have maximum
parity, healing won't trigger on these objects due to incorrect
verification of quorum.

quorum calculation getLatestFileInfo should be itself (#13717)
FileInfo quorum shouldn't be passed down, instead
inferred after obtaining a maximally occurring FileInfo.

This PR also changes other functions that rely on
wrong quorum calculation.

Update tests as well to handle the proper requirement. All
these changes are needed when migrating from older deployments
where we used to set N/2 quorum for reads to EC:4 parity in
newer releases.

fix: delete-markers without quorum were unreadable (#13351)
DeleteMarkers were unreadable if they had quorum based
guarantees, this PR tries to fix this behavior appropriately.

DeleteMarkers with sufficient should be allowed and the
return error should be accordingly with or without version-id.

This also allows for overwrites which may not be possible
in a multi-pool setup.

```

Furthermore allow `inspect` to do direct decode from `mc`, for example:

```
λ mc admin inspect --json local2/testbucket/nyc-taxi-data-10M.csv.zst/*|inspect -json
Output decrypted to inspect.5f0643b2.zip
```

- Correct error, forward non-EOF errors.
- Add some extra safety. Log FNF when no files.
- Add `xl-meta` zip support.
For `xl-meta` multiple inputs output object with names as key.
Automatically switches `xl-meta` to single-line output when multiple objects.
Add double-star wildcard support to xl-meta input.

and

```
a/b

```

we are going to document that this usecase is
not supported and we will never support it, if
any application does this users have to delete
the top level parent to make sure namespace is
accessible at lower level.

rest of the situations where the prefixes get
created across sets are supported as is.

Support variable server pools (#11256)
Current implementation requires server pools to have
same erasure stripe sizes, to facilitate same SLA
and expectations.

This PR allows server pools to be variadic, i.e they
do not have to be same erasure stripe sizes - instead
they should have SLA for parity ratio.

If the parity ratio cannot be guaranteed by the new
server pool, the deployment is rejected i.e server
pool expansion is not allowed.

fix: readData in bulk call using messagepack byte wrappers (#11228)
This PR refactors the way we use buffers for O_DIRECT and
to re-use those buffers for messagepack reader writer.

After some extensive benchmarking found that not all objects
have this benefit, and only objects smaller than 64KiB see
this benefit overall.

Benefits are seen from almost all objects from

1KiB - 32KiB

Beyond this no objects see benefit with bulk call approach
as the latency of bytes sent over the wire v/s streaming
content directly from disk negate each other with no
remarkable benefits.

All other optimizations include reuse of msgp.Reader,
msgp.Writer using sync.Pool's for all internode calls.

xl: Remove check-dir in ReadVersion (#11200)
The only purpose of check-dir flag in
ReadVersion is to return 404 when
an object has xl.meta but without data.

This is causing an extract call to the disk 
which can be penalizing in case of busy system
where disks receive many concurrent access.

fix: heal bucket metadata right before healing bucket (#11097)
optimization mainly to avoid listing the entire
`.minio.sys/buckets/.minio.sys` directory, this
can get really huge and comes in the way of startup
routines, contents inside `.minio.sys/buckets/.minio.sys`
are rather transient and not necessary to be healed.

Reduce WriteAll allocs (#10810)
WriteAll saw 127GB allocs in a 5 minute timeframe for 4MiB buffers 
used by `io.CopyBuffer` even if they are pooled.

Since all writers appear to write byte buffers, just send those 
instead and write directly. The files are opened through the `os` 
package so they have no special properties anyway.

This removes the alloc and copy for each operation.

REST sends content length so a precise alloc can be made.

ListObjects Metadata Caching (#10648)
Design: https://gist.github.com/klauspost/025c09b48ed4a1293c917cecfabdf21c

Gist of improvements:

* Cross-server caching and listing will use the same data across servers and requests.
* Lists can be arbitrarily resumed at a constant speed.
* Metadata for all files scanned is stored for streaming retrieval.
* The existing bloom filters controlled by the crawler is used for validating caches.
* Concurrent requests for the same data (or parts of it) will not spawn additional walkers.
* Listing a subdirectory of an existing recursive cache will use the cache.
* All listing operations are fully streamable so the number of objects in a bucket no 
  longer dictates the amount of memory.
* Listings can be handled by any server within the cluster.
* Caches are cleaned up when out of date or superseded by a more recent one.

Add storage layer contexts (#10321)
Add context to all (non-trivial) calls to the storage layer. 

Contexts are propagated through the REST client.

- `context.TODO()` is left in place for the places where it needs to be added to the caller.
- `endWalkCh` could probably be removed from the walkers, but no changes so far.

The "dangerous" part is that now a caller disconnecting *will* propagate down,  so a 
"delete" operation will now be interrupted. In some cases we might want to disconnect 
this functionality so the operation completes if it has started, leaving the system in a cleaner state.

- Implement a new xl.json 2.0.0 format to support,
  this moves the entire marshaling logic to POSIX

- Implement list object versions
- Migrate to siphash from crchash for new deployments
  for object placements.
