As in the pack protocol version 2 we want to
negotiate the capabilities before any other exchange
we will have a function which will take care of the
whole negotiation process.
It will be placed in fetch-pack.c for now as there
we have access to its internal variables and we'll
work on a `struct fetch_pack_args`. Eventually we
want to move it to a better place such as transport.c
