socklen_t underlying type can be signed or unsigned depending on
platform. This is fine, just cast it to size_t before comparison.
Fixes: warning: result of comparison of unsigned expression < 0 is
always false [-Wtautological-unsigned-zero-compare]

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

recvfrom() is not a cancellation point in pthreads-win32, see
https://sourceware.org/pthreads-win32/manual/pthread_cancel.html
In order to be able to cancel the reader thread on Win32 properly we first
shutdown the socket then call CancelIoEx to abort pending IO. Subsequent
recvfrom() calls will fail with WSAESHUTDOWN causing the thread to exit.
Fixes ticket #5717.

It is a common mistake that people only increase fifo_size when they experience
drops, unfortunately this does not help for higher bitrate (> 100 Mbps) streams
when the reader thread simply might not receive the packets in time (especially
under high CPU load) if the default 64 KB of kernel buffer size is used.
New default is determined so that common linux systems can set this buffer size
without tuning kernel parameters.

That alone supports specifying the interface based on its address. Getting the
interface index from the local address seems quite a bit of work in a platform
independent way...
Obviously for IPv6 we still always use MCAST_JOIN_SOURCE_GROUP.
As a side effect this also fixes ticket #7459.

We already use localaddr for the multicast joins without source filters, so we
should use them for source filters as well. This patch only fixes the
IP_ADD_SOURCE_MEMBERSHIP and the IP_BLOCK_SOURCE case.
Unless we do this, the kernel automatically selects an interface based on the
source address, and that interface might be different from the one set in
localaddr. For blocked sources this even casues EINVAL because we joined the
multicast group on a different interface.

This allows getting data only from a specific source IP. This is useful not
only for unicast but for multicast as well because multicast source
subscriptions do not act as source filters for the incoming packets.
