Windows support

[SanderMertens]

Add windows support to corto.

Is MSVC supported? Some of the generated code contains definitions such as if defined _MSC_VER which indicates VS support, but the tutorial (here) has install option only for $ curl https://corto.io/install | sh

Any info on how to get this going with Visual Studio (for a complete beginner of Corto)?

At this point Windows support is in very early stages. I don't expect we will have this finished until the beginning of next year- unless one of our users has an urgent need for it.

I cannot say "urgent need" - but enabling windows will greatly help me understand this better and I am planning on contributing some adapters. Debugging on Linux is next to nightmare to me (compared with VS debugging).

What is the gap / pending for the Windows portability? Is it the tooling problem or code/compilation problem?

It may not be 100% (such as generating VS solution files etc.) - but even some compilable code is fine - I can take it from there.

There are two main pending tasks for Windows support:

1. Translate non-standard C POSIX functions to the Windows API (threads, mutex locking etc).
2. Translate the buildsystem commands to Windows

All of the platform-specific code is isolated in just a few files and have been wrapped by corto functions so the code has been prepared for it, though I expect the amount of work to still be considerable.
