New pidfd_open (2) system call and other improvements

The pidfd_open (2) system call is intended to help solve problems when reusing the PID controller, adds support for umwait x86 instructions to increase user space energy efficiency, and support for a light and flexible built-in ACRN hypervisor. Don't forget to support 16 million new IPv4 addresses in the range.
