windows: delete redundant headers

`winsock2.h` pulls in `windows.h`. `ws2tcpip.h` pulls in `winsock2.h`.
`winsock2.h` and `ws2tcpip.h` are also pulled by `curl/curl.h`.

Keep only those headers that are not already included, or the code under
it uses something from that specific header.

examples: adhere to curl code style

All plain C examples now (mostly) adhere to the curl code style. While
they are only examples, they had diverted so much and contained all
sorts of different mixed code styles by now. Having them use a unified
style helps users and readability. Also, as they get copy-and-pasted
widely by users, making sure they're clean and nice is a good idea.

573 checksrc warnings were addressed.
