Newest patch.

This new patch implements Thomas idea of generating appropriate library cal=
ls
for the different ways that gfortran handles coarrays.

* gcc/fortran/trans-decl.c:
  . Add definitions for gfor_fndecl_caf_random_init and
    gfor_fndecl_cas_random_init.

* gcc/fortran/trans-intrinsic.c:
  . For -fcoarray=3Dlib, generate a call to _gfortran_caf_random_init().
  . For -fcoarray=3Dshared, generate a call to _gfortran_cas_random_init().
  . For -fcoarray=3Dsingle or without the -fcoarray option, generate a call
    to _gfortran_random_init().

* gcc/fortran/trans.h:
  . Add declares for gfor_fndecl_caf_random_init and
    gfor_fndecl_cas_random_init

* libgfortran/intrinsics/random_init.f90:
  . Rework _gfortran_random_init(), but preserve the ABI.=
