Initial attempt at building Windows binaries via Appveyor.

The appveyor.yml build configuration file is located in the misc/ subdir
along with a couple helper files so to not pollute the FreeTDS source
tree root dir.

The build script downloads, builds (but doesn't link in them yet as this
just needs changes to the FreeTDS CMake setup) both OpenSSL
(by Shinning Light Productions
https://slproweb.com/products/Win32OpenSSL.html) and iconv (Yukihiro
Nakadaira's win-iconv https://github.com/win-iconv/win-iconv). Thanks
goes to them for their generous work.
