MINOR: h3: implement h3 stream context

Browse Source 
Define a new structure h3s used to provide context for a H3 stream. This
structure is allocated and stored in the qcs thanks to previous commit
which provides app-layer context storage.

For now, h3s is empty. It will soon be completed to be able to support
stateful demux : this is required to be able to demux an incomplete
frame if the rx buffer is full.
