[Vala] Socket bindings VAPI file

[Mikael Hermansson <mike tielie gmail com>]

Here is a small VAPI file that adds lowlevel socket API This is
Unix/Posix related API.

Right now I am using Posix as namespace.

Feel free to use/change or add to vala SVN.

Right now it has support for Posix socket API:

socket()
connect()
bind()
listen ()
accept()
getaddrinfo()

and its related structures.
