av_neterrno(err) compares err to errno on unix
av_neterrno(err) compares WSAerr to WSASomething() on windows

In case the WSAerr part irritates you, how would you solve this? Adding
a huge switch/case blob? After all you hate #ifdefs in other part of the
code, including the errno handling, thus we need to pass only unix errno
name, not windows ones.
