/**
 * Global list of guest operating system types.
 *
 * New entries can be added, however other components depend on the values (e.g.
 * the guest additions) so the existing values MUST stay the same.
 *
 * Summary of the value bits:
 *      - bits 31:24 - 0xff000000 - Reserved; more OS version bits if needed.
 *      - bits 23:16 - 0x00ff0000 - OS family.
 *      - bits 15:12 - 0x0000f000 - Major OS version or (Linux) distro.
 *      - bit  11    - 0x00000800 - Should've been arch, only use by WinNT31.
 *      - bits 10:08 - 0x00000700 - Architecture.
 *      - bits 07:00 - 0x000000ff - Major distro release (Linux), or more bits
 *                                  for major OS version.
 *
 * They are grouped into families.  A family identifer is always has
 * mod 0x10000 == 0.  The bits making up the family component is given by
 * VBOXOSTYPE_OsFamilyMask, as we probably won't need 32K OS families and
 * currently restrict ourselves to 256 (currently only 14 + unknown have been
 * defined).
 *
 * The VBOXOSTYPE_OsTypeMask value contains the OS family and the major OS
 * version / distro. So use with care.
 *
 *
 * The VBOXOSTYPE_OsMask value contains all bits except for the architecture.
 * Use this and VBOXOSTYPE_ArchitectureMask for morphing the architecture of an
 * specific OS type.
 *
 * The subdivision of the OS type bits other than the family (and architecture),
 * i.e. VBOXOSTYPE_OsTypeMask & ~VBOXOSTYPE_OsFamilyMask, are specific to each
 * OS family.  For Linux the 0xf000 mask currently identifies the distro and
 * 0xff the major release of that distro in most cases.  While for most other
 * families 0xf000 is used for identifying major OS releases (Windows is out of
 * space with Windows 11, so will have to think of something new there when/if
 * the next major release is out).
 *
 * @note    Do NOT use bit 11 (0x800) for anything. It is currently only used by
 *          VBOXOSTYPE_WinNT3x and we'd like to keep it that way in case we ever
 *          end up needing more than three new architectures.
 *
 * @note    Cleaning up the value structure here is a bit late.  The problem is
 *          the use of this type in VBoxGuestInfo (VMMDevReq_ReportGuestInfo).
 *          Any radical change here would require a new version (v3) of that
 *          request and a safe protocol for dealing with backwards / forwards
 *          compatiblity on both sides.  Then we need a very thoughful
 *          partitioning of the value bits, picking new constants and mapping
 *          from old to new types (we only need the one direction).
 *
 * @todo    r=bird: A more sensible layout of the bits would, imo be:
 *              - bit  31    - 0x80000000 - the sign bit, forever unused.
 *              - bits 30:24 - 0x7f000000 - OS family
 *              - bits 23:16 - 0x00ff0000 - OS sub-family / distro.
 *              - bits 15:08 - 0x0000ff00 - OS major release.
 *              - bits 07:04 - 0x000000f0 - Reserved for future hacks.
 *              - bits 03:00 - 0x0000000f - Architecture.
 *          Basic conversion could be done by value shifting, though using a map
 *          with known values would allow for more thorough cleanup.
