  syscons(4) and vt(4) can be built together now.

  Allow to disable syscons(4) if "hw.syscons.disable" kenv is set.
267626 Log:
  Suspend vt(4) initialization if "kern.vt.disable" kenv is set.

  Use a common tunable to choose between vt(4)/sc(4)
  With this change and previous work from ray@ it will be possible to put
  both in GENERIC, and have one enabled by default, but allow the other to
  be selected via the loader.
  (The previous implementation had separate kern.vt.disable and
  hw.syscons.disable tunables, and would panic if both drivers were
  compiled in and neither was explicitly disabled.)

  Fix vt(4) detection in kbdcontrol and vidcontrol
  As sc(4) and vt(4) coexist and are both enabled in GENERIC, the existence
  of a vt(4) sysctl is not sufficient to determine that vt(4) is in use.
  Reported by:  Trond Endrestøl
268045 by emaste@ Log:
  Add vt(4) to GENERIC and retire the separate VT config
  vt(4) and sc(4) can now coexist in the same kernel.  To choose the vt
  driver, set the loader tunable kern.vty=vt .

  The _SUPPORT knobs have a consistent meaning which differs from the
