790f793844 avutil/common: Don't auto-include mem.h
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.

Some callers assume that item_name is always set, so this may be
considered an API break.

53aa76686e avformat/udp: cancel pending IO on win32 manually
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.

15d160cc0b avformat/udp: increase the default buffer size of a receiving socket to 384K
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.

ab0812c1a8 avformat/udp: always use IP_ADD_SOURCE_MEMBERSHIP for subscribing to an UDP multicast source group in IPv4
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.

d3bda871f0 avformat/udp: specify the local address for some source filtered multicast joins
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.

8b05a7ffe4 lavf/udp: fix dead code.
Since d607861, service can not be NULL, only "0".
An UDP address with neither local port nor address leaves both
service and node to their default value, and POSIX specifies
that they are not allowed to be both NULL; "0" is equivalent
to an unspecified port for all currently known protocols.

Fix CID 1341570.

413c842a69 avformat/udp: Add a delay between packets for streaming to clients with short buffer
This commit enables sending UDP packets in a background thread with specified delay.
When sending packets without a delay some devices with small RX buffer
( MAG200 STB, for example) will drop tail packets in bursts causing
decoding errors.

To use it specify "fifo_size" with "packet_gap" .

The output url will looks like udp://xxx:yyy?fifo_size=<output fifo
size>&packet_gap=<delay in usecs>

2758cdedfb lavf: reorganize URLProtocols
Instead of a linked list constructed at av_register_all(), store them
in a constant array of pointers.

Since no registration is necessary now, this removes some global state
from lavf. This will also allow the urlprotocol layer caller to limit
the available protocols in a simple and flexible way in the following
commits.
