[FeedBack Required] Porting neovim to NetBSD

[Utkarsh Anand <utkarsh009%yandex.com@localhost>]

I am pleased to announce that neovim now builds on NetBSD with just one error 
in one of the dependencies. Please try it out here:
https://github.com/neovim/neovim
Make sure you make the following changes in 
.deps/usr/include/msgpack/vrefbuffer.h:
https://github.com/msgpack/msgpack-c/pull/655/commits/f65c26e280f3f2e05c45d2d7b9e21a0b494b0fcd
If you're facing any difficulties, please report back. Also, feel free to create a 
package for it.
PS: Additionally you'll also require packages like libtool, automake etc. for 
building it.
