When a socket is created it is sometime useful to store a specific information
for this socket.
This information can be for examples:
* a creation time
* a pid
* a uid/gid
* a container identifier
* a pointer to a more specific structure
* ...
The following patch is a proposition to add a private anonymous pointer
field to the common part of the sock structure.
We got rid of the private field a long time ago because not only
is it not needed, it tends to get abused.
