PR fortran/18918
* gfortran.h (gfc_isym_id): Rename GFC_ISYM_NUMIMAGES to
GFC_ISYM_NUM_IMAGES.
(gfc_fcoarray): Add GFC_FCOARRAY_LIB.
* intrinsic.c (add_functions): Update due to GFC_ISYM_NUM_IMAGES
rename.
* invoke.texi (-fcoarray=): Document "lib" argument.
* iresolve.c (gfc_resolve_this_image): Fix THIS IMAGE().
* libgfortran.h (libgfortran_stat_codes): Add comments.
* options.c (gfc_handle_coarray_option): Add -fcoarray=lib.
* simplify.c (gfc_simplify_num_images, gfc_simplify_this_image):
Handle GFC_FCOARRAY_LIB.
* trans.h (gfc_init_coarray_decl): New prototype.
(gfor_fndecl_caf_init, gfor_fndecl_caf_finalize,
gfor_fndecl_caf_critical, gfor_fndecl_caf_end_critical,

gfor_fndecl_caf_error_stop, gfor_fndecl_caf_error_stop_str,
gfort_gvar_caf_num_images, gfort_gvar_caf_this_image):
New global variables.
* trans-decl.c: Declare several CAF functions (cf. above).
(gfc_build_builtin_function_decls): Initialize those.
(gfc_init_coarray_decl): New function.
(create_main_function): Call CAF init/finalize functions.
* trans-intrinsic.c (trans_this_image, trans_num_images): New.
(gfc_conv_intrinsic_function): Call those.
