Also, sort the error map for multiple sites in ascending order
of deployment IDs, so that the error message generated is always
definitive order and same.

Add `ConnDialer` to abstract connection creation.
- `IncomingConn(ctx context.Context, conn net.Conn)` is provided as an entry point for
incoming custom connections.
- `ConnectWS` is provided to create web socket connections.
If `SkipReader` is called with a small initial buffer it may be doing a huge number if Reads to skip the requested number of bytes. If a small buffer is provided grab a 32K buffer and use that.
Fixes slow execution of `testAPIGetObjectWithMPHandler`.
Bonuses:
* Use `-short` with `-race` test.
* Do all suite test types with `-short`.
* Enable compressed+encrypted in `testAPIGetObjectWithMPHandler`.
* Disable big file tests in `testAPIGetObjectWithMPHandler` when using `-short`.
The code was advertenly passing max openfds to debug.SetMemoryLimit(),
fixing this accelerate go test in my machine.
This is only a testing bug, since the server context has always a valid
MaxMem, so the buggy code was never called in users environments.
Currently the status of a completed or failed batch is held in the
memory, a simple restart will lose the status and the user will not
have any visibility of the job that was long running.
In addition to the metrics, add a new API that reads the batch status
from the drives. A batch job will be cleaned up three days after
completion.
Also add the batch type in the batch id, the reason is that the batch
job request is removed immediately when the job is finished, then we
do not know the type of batch job anymore, hence a difficulty to locate
the job report
Hot load a policy document when during account authorization evaluation
to avoid returning 403 during server startup, when not all policies are
already loaded.
Add this support for group policies as well.
you can attempt a rebalance first i.e, start with 2 pools.
```
mc admin rebalance start alias/
```
and after that you can add a new pool, this would
potentially crash.

without atomic load() it is possible that for
a slow receiver we would get into a hot-loop, when
logCh is full and there are many incoming callers.
to avoid this as a workaround enable BATCH_SIZE
greater than 100 to ensure that your slow receiver
receives data in bulk to avoid being throttled in
some manner.
this PR however fixes the unprotected access to
the current workers value.
specifying customer HTTP client makes the gcs SDK
ignore the passed credentials, instead let the GCS
SDK manage the transport.
this PR fixes#19922 a regression from #19565
Currently, bucket metadata is being loaded serially inside ListBuckets
Objet API. Fix that by loading the bucket metadata as the number of
erasure sets * 10, which is a good approximation.
When a reconnection happens, `handleMessages` must be able to complete and exit.
This can be prevented in a full queue.

Add a queue cleaner in reconnected that will pop old messages so `handleMessages` can
send messages without blocking and exit appropriately for the connection to be re-established.
Messages are likely dropped by the remote, but we may have some that can succeed,
so we only drop when running out of space.
