MAJOR: muxes/htx: Handle inplicit upgrades from h1 to h2
The upgrade is performed when an H2 preface is detected when the first request
on a connection is parsed. The CS is destroyed by setting EOS flag on it. A
special flag is added on the HTX message to warn the HTX analyzers the stream
will be closed because of an upgrade. This way, no error and no log are
emitted. When the mux h1 is released, we create a mux h2, without any CS and
passing the buffer with the unparsed H2 preface.
