Willy Tarreau d4c33c8889 MEDIUM: samples: move payload-based fetches and ACLs to their own file
The file acl.c is a real mess, it both contains functions to parse and
process ACLs, and some sample extraction functions which act on buffers.
Some other payload analysers were arbitrarily dispatched to proto_tcp.c.

So now we're moving all payload-based fetches and ACLs to payload.c
which is capable of extracting data from buffers and rely on everything
that is protocol-independant. That way we can safely inflate this file
and only use the other ones when some fetches are really specific (eg:
HTTP, SSL, ...).

As a result of this cleanup, the following new sample fetches became
available even if they're not really useful :

  always_false, always_true, rep_ssl_hello_type, rdp_cookie_cnt,
  req_len, req_ssl_hello_type, req_ssl_sni, req_ssl_ver, wait_end

The function 'acl_fetch_nothing' was wrong and never used anywhere so it
was removed.

The "rdp_cookie" sample fetch used to have a mandatory argument while it
was optional in ACLs, which are supposed to iterate over RDP cookies. So
we're making it optional as a fetch too, and it will return the first one.
