I extended the HTTP library to support persistent HTTP 1.1 connections and also HTTP 1.0 keep-alive. The idle time after which persistent connection is closed is currently hardcoded, but there is a plan to add configuration parameter to control this time. The HTTP pipelining is currently not supported at this time.

Proposed ChangeLog entry:

13XX.	[func]		marcin
	Persistent HTTP/1.1 connections and HTTP/1.0 keep-alive
	are supported by RESTful API.

Linked #5445 to this ticket as I think this ticket covers it.

isConnectionAlive() uses read: I'd prefer it uses recv with the MSG_PEEK flag, now it is for a test...

Reading the code it seems fine. It builds and runs tests with success on my macOS. Please merge and close #5445.
