------------------------------+-----------------------------
 The standard C/POSIX functions malloc() and calloc() set errno in case of
 an error. A dependency to errno pulls in getreent() which pulls in a lot
 of data structures and functions. This is an issue in low level code
 especially in the area of a basic board support package initialization and
 device drivers.

 Provide rtems_malloc() and rtems_calloc() functions declared in
 <rtems/malloc.h> which do the same as the corresponding C/POSIX functions
 except setting errno.

 The posix_memalign() and aligned_alloc() functions do not have this issue
 with the errno.
