Bring in GSoC code: SysV IPC in userspace

This commit brings in the code for the GSoC 2013 project "SysV IPC in
userspace". This is not extensively tested and probably needs some
additional work which Larisa has agreed to do.

For bug reports and improvements use the usual channels.

To use this functionality, which is built into libc, see the man page
for the userspace SysV IPC daemon sysvipcd(8).
