The vga and splash devices are part of the sc(4) system console. vt(4)
uses the vt_vga driver instead, and has some limited splash support
directly in vt_core.c. Leave the sc(4) options in GENERIC/MINIMAL (for
now) but group them together under an sc(4) comment.

On amd64 XENHVM depends on the xentimer device for PVH early startup,
so both should be added or removed together (like the current
dependency with xenpci). Fix this by adding xentimer to NOTES and
updating the comments on the config files. Note that on i386 there's
no such dependency between xentimer and XENHVM, since there's no PVH
support.
While there also fix the MINIMAL i386 build to include the xentimer,
so it keeps the same functionality as before xentimer was split from
XENHVM.

Implement vt_vbefb to support Vesa Bios Extensions (VBE) framebuffer with VT.
vt_vbefb is built based on vt_efifb and is assuming similar data for
initialization, use MODINFOMD_VBE_FB to identify the structure vbe_fb
in kernel metadata.
struct vbe_fb, is populated by boot loader, and is passed to kernel via
metadata payload.

tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).
This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp
[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).
ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.
(MFC commentary)
This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.
I have no plans to do this MFC as of now.
