[PATCH 10/22] Remove client_codecs global variable, moved inside the 'Stream' class

[Christophe de Dinechin <christophe@xxxxxxxxxxxx>]

From: Christophe de Dinechin <dinechin@xxxxxxxxxx>

It makes sense to place the codecs inside the Stream which is charged
with setting it up, until we create a proper abstraction for input
messages similar to what Message does for output messages in follow-up
patches.
