Previously, the function would lead to an infinite wait (by
returning AVERROR(EAGAIN)) on sockets indicating an error
via either of these poll flags.

Support the URL_FLAG_NONBLOCK semantic and uniform the protocol.
The quick retry loop is already part of retry_transfer_wrapper.
The polling routine is common to the network protocols:
udp, tcp and, once merged, sctp.
Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR()
error codes. Provide fallback definitions of other errno.h network
errors, mapping them to the corresponding winsock errors.
This eases catching these error codes in common code, without having
to distinguish between FF_NETERRNO(EAGAIN) and AVERROR(EAGAIN).
This fixes roundup issue 2614, unbreaking blocking network IO on
windows.

Not all users of this function will have a full struct sockaddr_storage
available, and casting other sockaddrs to sockaddr_storage is wrong,
while any sockaddr can be cast to a base sockaddr.

The header probably isn't the right permanent place for this function, but
it is quite small, and consensus seems to be that it can stay in the
header for now, instead of creating a new file network.c just for this one.

for broken OSes. This is included in rtsp.h, as opposed to os_support.h.
Should fix OS/2 broken build on fate.

This patch also changes FF_NETERROR() to be an AVERROR(), i.e. it is always
negative, whereas it was previously positive.

sockaddr (in case it's not missing) so it always works on the system that
we are defining it for, in a RFC-2553/3493-compliant way (i.e. containing
a ss_family field). which is used in udp.c. Patch by Martin Storsjö

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
