Harshavardhana 0879a4f743 rest/storage: Remove racy LastError usage (#8817)
instead perform a liveness check call to
verify if server is online and print relevant
errors.

Also introduce a StorageErr string error type
instead of errors.New() deprecate usage of
VerifyFileError, DeleteFileError for gob,
change in datastructure also requires bump in
storage REST version to v13.

Klaus Post 37b32199e3 Validate XL sets on format (#8779)
When formatting a set validate if a host failure will likely lead to data loss.

While we don't know what config will be set in the future 
evaluate to our best knowledge, assuming default settings.

lock: improve locker initialization at init (#8776)
Use reference format to initialize lockers
during startup, also handle `nil` for NetLocker
in dsync and remove *errorLocker* implementation

Add further tuning parameters such as

 - DialTimeout is now 15 seconds from 30 seconds
 - KeepAliveTimeout is not 20 seconds, 5 seconds
   more than default 15 seconds
 - ResponseHeaderTimeout to 10 seconds
 - ExpectContinueTimeout is reduced to 3 seconds
 - DualStack is enabled by default remove setting
   it to `true`
 - Reduce IdleConnTimeout to 30 seconds from
   1 minute to avoid idleConn build up

Klaus Post c7844fb1fb posix: cache disk ID for a short while (#8564)
`*posix.getDiskID()` takes up to 30% of all CPU due to the `os.Stat` call on `GET` calls.

Before:
```
Operation: GET - Concurrency: 12
* Average: 1333.97 MB/s, 1365.99 obj/s, 1365.98 ops ended/s (4m59.975s)
* First Byte: Average: 7.801487ms, Median: 7.9974ms, Best: 1.9822ms, Worst: 110.0021ms

Aggregated, split into 299 x 1s time segments:
* Fastest: 1453.50 MB/s, 1488.38 obj/s, 1492.00 ops ended/s (1s)
* 50% Median: 1360.47 MB/s, 1393.12 obj/s, 1393.00 ops ended/s (1s)

TLDR; `os.Stat` is not free.

Klaus Post 1dd38750f7 Remove read-ahead for small files (#8522)
We should only read ahead if we are reading big files. We enable it for files >= 16MB.

Benchmark on 64KB objects.

Before:

```
Operation: GET
Errors: 0
Average: 59.976s, 87.13 MB/s, 1394.07 ops ended/s.
Fastest: 1s, 90.99 MB/s, 1455.00 ops ended/s.
50% Median: 1s, 87.53 MB/s, 1401.00 ops ended/s.
Slowest: 1s, 81.39 MB/s, 1301.00 ops ended/s.
```

After:

```
Operation: GET
Errors: 0
Average: 59.992s, 207.99 MB/s, 3327.85 ops ended/s.
Fastest: 1s, 219.20 MB/s, 3507.00 ops ended/s.
50% Median: 1s, 210.54 MB/s, 3368.00 ops ended/s.
Slowest: 1s, 179.14 MB/s, 2865.00 ops ended/s.
```

The 64KB buffer is actually a small disadvantage for this case, but I believe it will be better in general than no buffer.

Harshavardhana ff5bf51952 admin/heal: Fix deep healing to heal objects under more conditions (#8321)
- Heal if the part.1 is truncated from its original size
- Heal if the part.1 fails while being verified in between
- Heal if the part.1 fails while being at a certain offset

Other cleanups include make sure to flush the HTTP responses
properly from storage-rest-server, avoid using 'defer' to
improve call latency. 'defer' incurs latency avoid them
in our hot-paths such as storage-rest handlers.

an error so healing empty parts can work properly.

poornas 5a80cbec2a Add double encryption at S3 gateway. (#6423)
This PR adds pass-through, single encryption at gateway and double
encryption support (gateway encryption with pass through of SSE
headers to backend).

If KMS is set up (either with Vault as KMS or using
MINIO_SSE_MASTER_KEY),gateway will automatically perform
single encryption. If MINIO_GATEWAY_SSE is set up in addition to
Vault KMS, double encryption is performed.When neither KMS nor
MINIO_GATEWAY_SSE is set, do a pass through to backend.

When double encryption is specified, MINIO_GATEWAY_SSE can be set to
"C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3
encryption at gateway/backend or both to support more than one option.
