[libmicrohttpd] http2 support

[Santos Das]

Hi ,

I am looking at the following email for the support if HTTP2 with MHD.  

I am wondering can we not support HTTP1.1 and HTTP2.0 on the single server port, i.e if the client is using HTTP1.1 , server should reply on HTTP1.1 and if the client is running with HTTP2.0 then the server should reply with HTTP2.0.

https://lists.gnu.org/archive/html/libmicrohttpd/2018-03/msg00032.html

Looking at the changes done https://github.com/maru/libmicrohttpd-http2 , it seems it supports either HTTP1.1 or HTTP2.0. Can this not be done on a connection basis not the server basis.

User just adds "MHD_USE_HTTP2" flag when calling MHD_start_daemon.
