Framework for a WM8904 audio driver.  The initial driver check-in is simply Ken Pettit's VS1053 driver forced to compile with only WM8904 definitions

SAMA5D4-EK NxWM Configuration:  Increase number of preallocated watchdogs and don't save child status (it is not being reaped)

NxWM: Increase default priority of mouse and keyboard listener threads. Does not seem to make any difference but still seems like a good idea

graphics/nxconsole/nxcon_scroll.c:  Fix scrolling in the NxConsole for the case of the framebuffer device.  In this case, the logic for clearing the vacated region at the bottom was missing so garbage up from the last, uncleared line

NxWidgets::CGlyphSliderHorizontal: No longer uses a hard-coded slider height; the slider height is now provided as a parameter, replacing the widget height which is now calculated from the glip image height

Rename CONFIG_NX_MOUSE to CONFIG_NX_INPUT, then add CONFIG_NX_XYINPUT_MOUSE and CONFIG_XYINPUT_TOUCHSCREEN

NxWM::CMediaPlayer:  Fix of state related bugs + Size if CLabel is increased (in preparation for becoming a CListBox)

Documentation: Update all images.  I think they were all damaged by a wild in place sed in some recent change

maXTouch: Add thresholding so that MOVE reports are not generated unless there is a significant change in the reported position

SAMA5 LCDC: Back out the delay kludge.  Increase the LCDC input clock from MCK to 2*MCK was sufficient for all timing instbility problems
