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

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)

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