	* trans.c (gfc_allocate_with_status): Split into two functions
	gfc_allocate_using_malloc ad gfc_allocate_usig_lib.
	(gfc_allocate_using_malloc): The status parameter is now the
	actual status rather than a pointer. Code cleanup.
	(gfc_allocate_using_lib): Ditto. Add new parametrs errmsg and
	errlen. Pass these to the coarray lib.
	* trans-openmp.c (gfc_omp_clause_default_ctor): Update calls to
	gfc_allocate_allocatable.
	(gfc_omp_clause_copy_ctor): Ditto.
	(gfc_trans_omp_array_reduction): Ditto.
	* trans-stmt.c (gfc_trans_allocate): Ditto. Update call to
	gfc_allocate_using_malloc. Pass stat rather than pstat to the
	allocate fuctions. If using coarray lib, pass errmsg and errlen
	to the allocate functions.
	* trans-array.c (gfc_array_allocate): Add new parameters errmsg
	and errlen. Replace parameter pstat by status. Code cleanup. Update
	calls to gfc_allocate_allocatable and gfc_allocate_using_malloc.
	* trans-array.h (gfc_array_allocate): Update signature of
	gfc_array_allocate.
