Remove networking shim from Windows EAL. Replace it with system headers with two workarounds:
1. Windows Sockets headers contain `#define s_addr S_un.S_addr`, which conflicts with `s_addr` field of `struct rte_ether_hdr`. Undefining this macro in <rte_ether.h> had been breaking some usages of DPDK and Windows headers in one file. Renaming is planned: https://mails.dpdk.org/archives/dev/2021-March/201444.html Temporarily disable `s_addr` macro around `struct rte_ether_hdr` definition to avoid conflict. Place source MAC address in both `s_addr` and `S_un.S_addr` fields, so that access works either directly or through the macro. 2. Provide some IPPROTO_* constants and IPVERSION, missing on Windows.
