Xduoo X3 Add tree scrolling FS#13240, Emulate Multibutton presses

Browse source 
Fixes deficiencies with the button system on the X3

  The x3 has an interesting button layout.
  Multiple key presses are NOT supported unless
  [BUTTON_POWER] is one of the combined keys

  As you can imagine this causes problems as the power button takes
  precedence in the button system and initiates a shutdown if the
  key is held too long
  instead of BUTTON_POWER use BUTTON_PWRALT in combination with other keys
  IF using as a prerequsite button then BUTTON_POWER should be used

  Multiple buttons are emulated by button_read_device but there are a few
  caveats to be aware of:

  Button Order Matters!
   different keys have different priorities, higher priority keys 'overide'
   the lower priority keys
  VOLUP[7] VOLDN[6] PREV[5] NEXT[4] PLAY[3] OPTION[2] HOME[1]

  There will be no true release or repeat events, the user can let off the
   button pressed initially and it will still continue to appear to be
   pressed as long as the second key is held

Tree scrolling is PLAY+NEXT or PLAY+PREV
