When re-connecting to the remote redis server
try to re-resolve if the redist hostname
was an FQDN and not IP address.

Use a small stack buffer instead of obtaining a thread-local one when
writing directly to a GString.

For typed hash tables, enforce the correct type in the arguments to the
hashing and equality functions.
Adapt existing affected callback functions and change their arguments
from void* to the respective types.
Add reverse casts to GHashFunc and GEqualFunc in instances where these
functions are used in non-typed hash tables (that should be converted at
a later point).
Add convenience macro to create typed wrapper functions for hash tables
that use "direct" hashing (i.e. the pointer value).
Add wrappers for existing GLib functions that have generic arguments so
that they can be used in typed hash tables.

To support asynchronous pollers which may hold references on underlying
sockets, let the poller close the socket after it has released its
references. This prevents cases of file descriptor re-use while an
underlying socket is still open.
Add reset_socket() to be used in place of close_socket() which does the
same thing except the actual closing of the socket.
Add poller_del_item_callback() for cases where more action than just
closing the file descriptor is needed.

Older glibc uses a strange (and seemingly broken) approach to verifying
the cmsg structures by inspecting the *next* cmsg header and using its
length to see if there is enough space in the buffer. Since we're
constructing the cmsg list, at this point there is no next cmsg yet,
therefore causing spurious failures of CMSG_NXTHDR.
Work around this by initialising the entire buffer first.

UDP packets sent in response to a UDP request should have the same
source address as the request's destination address.
This can be achieved with sockets bound to a specific address, but in
the case of ANY-bound sockets, we can use the PKTINFO mechanism to do
this.
Extend control_ng_process() to accept an extra socket address
corresponding to the local address to use. Extend the signature of the
callback function (to do the actual sending) accordingly.
Extend socket_sendiov() to be able to set the PKTINFO cmsg when sending
a packet.
Add socket_sendto_from() as a convenience wrapper.
Extend control_udp_incoming() to pass the address from
udp_buf->local_addr back to socket_sendiov().

Similar to recvfrom_ts, this return the local (destination) address of
the received packet, extracted from the PKTINFO struct.

When ports are closed early (while the call is still running), we must
first update a slave rtpengine with this new information (that these
ports are now closed) before actually releasing the ports ourselves. Not
doing so leads to a race condition where the master instance re-uses a
port that was just closed before the slave instance knows about the port
being closed.
We implement this using a thread-local list to keep track of ports that
were released while processing a control message, and process this list
to actually close the ports only after Redis has been updated.
Additional calls to the function to close the ports are placed in
strategic locations to make sure this is triggered in every code path.

Handling of dual stack v4/v6 was previously done by the individual
listener objects for INADDR_ANY listening addresses. If listening on
INADDR_ANY was requested, then each listener would create two instances,
one for IPv4 and one for IPv6. This works fine for INADDR_ANY but fails
for listening on host names that resolve to multiple addresses, such as
`localhost`.
Solve this by relieving the listener objects from handling this and
instead handle it in the code setting up the listeners. If a host name
resolves to multiple addresses, then set up multiple listeners (up to
two supported currently). This allows us to listen on `localhost` by
default and have both 127.0.0.1 and ::1 active. INADDR_ANY is handled
specially by also setting up :: in that case.

Needed to be able to set graphite socket timeout.
Useful when one wants rtpengine to force the graphite connection
to fail faster, in case graphite server gets filtered while
connection is ongoing.
