sock api: fix registrations and client reads

- When clients connect, instead of returing registration indicies return
handles. By convention socket registrations will have the MSB set to 1.
This makes it easy to distinguish them from shm registrations.
- Fix client reads to allow for messages larger than 4kB (needed for the
creat reply wherein the message table is provided).
