MEDIUM: h2: dynamically allocate the demux buffer on Rx

This patch implements a very basic Rx buffer management. The mux needs
an rx buffer to decode the connection's stream. If this buffer it
available upon Rx events, we fill it with whatever input data are
available. Otherwise we try to allocate it and subscribe to the buffer
wait queue in case of failure. In such a situation, a function
"h2_dbuf_available()" will be called once a buffer may be allocated.
The buffer is released if it's still empty after recv().
