Hello,

This series adds an IPC mechanism to pass data and file descriptors 
between two processes. The interface is asynchronous and bi-directional.

There are quiet a few changes since the RFC,

- Switch to an event notifications and signals for the ingress code 
  path, making the interface asynchronous.
- Removed any protocol helpers in the IPC object, a protocol should be 
  implemented on top of the IPC.
- Added documentation.
- Switched to SOCK_DGRAM.
- Send both data and file descriptors in the same sendmsg().
- Fixed spelling and silly errors in the code.
- Merged test case in a single binary.
