* startup/bspstart.c: Add capability for bootcard.c BSP Initialization
	Framework to ask the BSP where it has memory for the RTEMS Workspace
	and C Program Heap. These collectively are referred to as work area.
	If the BSP supports this, then it does not have to include code to
	split the available memory between the two areas. This reduces the
	amount of code in the BSP specific bspstart.c file. Additionally, the
	shared framework can initialize the C Library, call
	rtems_debug_enable(), and dirty the work area memory. Until most/all
	BSPs support this new capability, if the BSP supports this, it should
	call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac.
	When the transition is complete, this autoconf macro can be removed.
