Build latest stable Python 3.x for WSL (Windows Subsystem for Linux)

build-python3-wsl.mkd

The WSL OpenSSL libraries are missing headers, preventing actually using them to compile anything.

1. Grab OpenSSL source and checkout latest stable version (1.*)
2. Build and Install OpenSSL
3. Grab Python source and checkout latest stable version (3.*)
4. Build and Install Python w. OpenSSL available.

TIP: Be sure to use the \\wsl$\ filesystem, and link out from that, vs creating a sym-link from Windows into WSL. If your git or other operations are slow, look into this.
