Removed special-case utcb shared page from posix services.

Browse Source 
Previously a so-called utcb shared page was used for transfering
data between posix services. This was a special shmat/get/dt case
allocating from its own virtual pool. Now the term utcb is renamed
as a shared page and integrated with the shm* handling routines.

Generic l4 threads will use long-ipc and not this method. Posix
services will continue to communicate on a shared page for now.
