[FFmpeg-cvslog] os_support: define socket shutdown SHUT_xxx macros if they are not defined

[Peter Ross]

ffmpeg | branch: master | Peter Ross <pross at xvid.org> | Sat Nov 24 23:26:13 2018 +1100| [b41f378fc4ddb1a34aebe459805d3c8dbcc96b36] | committer: Peter Ross

os_support: define socket shutdown SHUT_xxx macros if they are not defined

this section has been moved into the CONFIG_NETWORK block, since it only
affects network enabled builds.

sys/socket.h (with WIN32 guard) is needed to check if the SHUT_xxx macro exists.
