All functions that create listener objects take a read-only endpoint, so
make them as const.
Remove the extra TOS argument to make all signatures the same.

We have long switched to having a single primary global poller, so
there's no point in passing the poller pointer around and storing it in
associated objects. Remove all remnants of non-global pollers.

This brings master up to date with branch `rfuchs/socket-rework` at
commit `b1bcc096b7`. The branches have diverged too much for a proper
merge, so this is a manual (squashed) merge.
The old master before this merge can be found in branch
`old-master-before-socket-rework` (commit `82199216b2`).
This is a complete rewrite of all socket handling routines. The most
important functional change is that sockets aren't indiscriminately
bound to INADDR_ANY (or rather in6addr_any), but instead are always
bound to their respective local interface address and with the correct
address family.
Side effects of this are that in multi-homed environments, multiple
sockets must be opened (one per interface address and family) which must
be taken into account when considering RLIMIT_NOFILE values. As a
benefit, this change allows rtpengine to utilize the full UDP port space
per interface address, instead of just one port space per machine.
The socket abstraction also makes it possible to support RTP over TCP in
the future.

Introduce generic "objects" with reference counting primitives and automatic
resource deallocation when no refs are left ("garbage collection"). Overhaul
poller framework to make extensive use of these objects to allow for future
thread-concurrent operation.
No locking added anywhere yet except in poller. Poller is still not 100%
thread safe, but close.
Valgrind reports no errors or memleaks.
