re PR fortran/51976 ([F2003] Support deferred-length character components of derived types (allocatable string length))

PR fortran/51976
* gfortran.h (symbol_attribute): Add deferred_parameter attribute.
* primary.c (build_actual_constructor): It is not an error if
a missing component has the deferred_parameter attribute;
equally, if one is given a value, it is an error.
* resolve.c (resolve_fl_derived0): Remove error for deferred
character length components. Add the hidden string length
field to the structure. Give it the deferred_parameter
attribute.
* trans-array.c (duplicate_allocatable): Add a strlen field
which is used as the element size if it is non-null.
(gfc_duplicate_allocatable, gfc_copy_allocatable_data): Pass a
NULL to the new argument in duplicate_allocatable.
(structure_alloc_comps): Set the hidden string length as
appropriate. Use it in calls to duplicate_allocatable.
(gfc_alloc_allocatable_for_assignment): When a deferred length
backend declaration is variable, use that; otherwise use the
string length from the expression evaluation.
* trans-expr.c (gfc_conv_component_ref): If this is a deferred
character length component, the string length should have the
value of the hidden string length field.
(gfc_trans_subcomponent_assign): Set the hidden string length
field for deferred character length components. Allocate the
necessary memory for the string.
(alloc_scalar_allocatable_for_assignment): Same change as in
gfc_alloc_allocatable_for_assignment above.
* trans-stmt.c (gfc_trans_allocate): Likewise.
* trans-intrinsic (size_of_string_in_bytes): Make non-static.
* trans-types.c (gfc_get_derived_type): Set the tree type for
a deferred character length component.
* trans.c (gfc_deferred_strlen): New function.
* trans.h (size_of_string_in_bytes,gfc_deferred_strlen): New prototypes.
