On macOS, if a process already listens on 127.0.0.1:PORT, net.Listen() falls back
to IPv6 address ie minio will start listening on IPv6 address whereas another
(non-)minio process is listening on IPv4 of given port.
To avoid this error sutiation we check for port availability only for macOS.
Note: checkPortAvailability() tries to listen on given port and closes it.
It is possible to have a disconnected client in this tiny window of time.
Creds don't require secretKeyHash to be calculated
everytime, cache it instead and re-use.
This is an optimization for bcrypt.
Relevant results from the benchmark done locally, negative
value means improvement in this scenario.

An external test that runs cmd.Main() has a difficulty to set cmd arguments
and MINIO_{ACCESS,SECRET}_KEY values, this commit changes a little the current
behavior in a way that helps external tests.
Encode the path of the passed presigned url before calculating the signature. This fixes
presigning objects whose names contain characters that are found encoded in urls.
* Implement heal format REST API handler
* Implement admin peer rpc handler to re-initialize storage
* Implement HealFormat API in pkg/madmin
* Update pkg/madmin API.md to incl. HealFormat
* Added unit tests for ReInitDisks rpc handler and HealFormatHandler
For TLS peekProtocol do not assume the incoming request to be a TLS
connection perform a handshake() instead and validate.
Also add some security related defaults to `tls.Config`.
This restriction has lots of side affects, since
we do not have a mechanism to clear states like
this it is better not to keep them.
Network errors are common and can occur with
simple cable removal etc. Since we already have
a retry mechanism this error count and stateful
nature can bring problems on a long running
cluster.
This is a consolidation effort, avoiding usage
of naked strings in codebase. Whenever possible
use constants which can be repurposed elsewhere.
This also fixes `goconst ./...` reported issues.
`principalId` i.e user identity is kept as AccessKey in
accordance with S3 spec.
Additionally responseElements{} are added starting with
`x-amz-request-id` is a hexadecimal of the event time itself in nanosecs.
`x-minio-origin-server` - points to the server generating the event.
Fixes#3556
