Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

vPIT is used as a source of system timer by UEFI (e.g. OVMF).
This is ported from Bhyve, with a few changes:
- move to user space, using POSIX timer
- support timer mode 3
- improve the emulation of OUT and STATUS byte
- improve the emulation of counter behavior
- improve the emulation of CE update in periodic mode
- treat CR == 0 as 0x10000

Some firmware (e.g. UEFI) uses RTC CMOS to fetch the system's memory
configuration. Put lowmem / highmem info in the designated area.
This is a port of Bhyve vRTC's user-space logic.
v1 -> v2:
* move KB/MB/GB to macros.h
* move nvram offset definitions to rtc.h
