* Refactor HTTP server to address bugs
* Remove unnecessary goroutine to start multiple TCP listeners.
* HTTP server waits for shutdown to maximum of Server.ShutdownTimeout
than per serverShutdownPoll.
* Handles new connection errors properly.
* Handles read and write timeout properly.
* Handles error on start of HTTP server properly by exiting minio
process.
Fixes#4494#4476 & fixed review comments
This PR serves to fix following things in GCS gateway.
- fixes leaks in object reader and writer, not getting closed
under certain situations. This led to go-routine leaks.
- apparent confusing issue in case of complete multipart upload,
where it is currently possible for an entirely different
object name to concatenate parts of a different object name
if you happen to know the upload-id and parts of the object.
This is a very rare scenario but it is possible.
- succint usage of certain parts of code base and re-use.
Fixed header-to-metadat extraction. The extractMetadataFromHeader function should return an error if the http.Header contains a non-canonicalized key. The reason is that the keys can be manually set (through a map access) which can lead to ugly bugs.
Also fixed header-to-metadata extraction. Return a InternalError if a non-canonicalized key is found in a http.Header. Also log the error.
This is needed to avoid proxies buffering the connection
this is also a HTTP standard way to handle this situation
where server is sending back events in asynchronously.

When the browser asks for a GET presigned url, this latter is not
encoded and can be confusing when the user copies-pastes it somewhere,
especially when the path contains a space.

Current state-machine didn't honor a situation
which can arise when there is a combination of
- formatted
- unformatted
- corrupted
disks - this combination invariably goes into a
mode where all servers are waiting perpetually
forever thinking we will get quorum in future.
At this point there is a distant possibility of
ever getting a quorum since we don't even have
quorum number of disks offline.
We should exit and print a proper message per disk
to indicate what went wrong and what was detected
by the server.
