* resolve.c (check_uop_procedure): Prevent deferred length
characters from being trapped by assumed length error.

* trans-array.c (gfc_conv_scalarized_array_ref): Pass decl for
function as well as variable expressions.
(gfc_array_init_size): Add 'expr' as an argument. Use this to
correctly set the descriptor dtype for deferred characters.
(gfc_array_allocate): Add 'expr' to the call to
'gfc_array_init_size'.
* trans.c (gfc_build_array_ref): Expand logic for setting span
to include indirect references to character lengths.
* trans-decl.c (gfc_get_symbol_decl): Ensure that deferred
result char lengths that are PARM_DECLs are indirectly
referenced both for directly passed and by reference.
(create_function_arglist): If the length type is a pointer type
then store the length as the 'passed_length' and make the char
length an indirect reference to it.
(gfc_trans_deferred_vars): If a character length has escaped
being set as an indirect reference, return it via the 'passed
length'.
* trans-expr.c (gfc_conv_procedure_call): The length of
deferred character length results is set TREE_STATIC and set to
zero.
(gfc_trans_assignment_1): Do not fix the rse string_length if
it is a variable, a parameter or an indirect reference. Add the
code to trap assignment of scalars to unallocated arrays.
* trans-stmt.c (gfc_trans_allocate): Remove 'def_str_len' and
all references to it. Instead, replicate the code to obtain a
explicitly defined string length and provide a value before
array allocation so that the dtype is correctly set.
trans-types.c (gfc_get_character_type): If the character length
is a pointer, use the indirect reference.
