  1. Added ptrace utilities. 

    Some ptrace functions return structures through the data argument. This commit adds utilities to return data through this mechanism and function specialisations for a few of these functions (getting event messages or the siginfo_t struct). Once the next version of libc is released these utilities will be expanded to include the fpregs and user_regs structs.

Ptrace requests that are now satisfied by a more specific public function will return an unsupported operation error. This has involved adding an UnsupportedOperation to the nix::Error enum and removed the mapping from Error to Errno and from Error to std::io::Error.
