[PATCH 0/5] Optimize workspace/malloc initialization

The BSPs provide memory for the RTEMS Workspace and the separate C
Program Heap initialization via _Memory_Get().  Most BSPs provide
exactly one memory area.  Only two BSPs provide more than one memory
area (arm/altera-cyclone-v and bsps/powerpc/mpc55xxevb).  Only if more
than one memory area is provided, there is a need to use _Heap_Extend().
Provide two implementations to initialize the RTEMS Workspace and the
separate C Program Heap.  Let the BSP select one of the implementations
based on the number of provided memory areas.  This gets rid of a
dependency on _Heap_Extend().  It also avoids dead code sections for
most BSPs.

  wkspace.c: Change license to BSD-2-Clause
  score: Split wkspace.c
  build: Use common objects item for get memory
  score: Optimize Workspace Handler initialization
  libc: Optimize malloc() initialization
