Non-advancing I/O was failing; ExternalFileUnit was losing
track of what writes had been committed to the file. Fixed.
Also, support the common extension of $ and \ in a FORMAT
as being equivalent to ADVANCE=NO.

With derived type description tables now available to the
runtime library, it is possible to implement the concept
of "child" I/O statements in the runtime and use them to
convert instances of derived type I/O data transfers into
calls to user-defined subroutines when they have been specified
for a type. (See Fortran 2018, subclauses 12.6.4.8 & 13.7.6).
- Support formatted, list-directed, and NAMELIST
transfers to internal parent units; support these, and unformatted
transfers, for external parent units.
- Support nested child defined derived type I/O.
- Parse DT'foo'(v-list) FORMAT data edit descriptors and passes
their strings &/or v-list values as arguments to the defined
formatted I/O routines.
- Fix problems with this feature encountered in semantics and
FORMAT valiation during development and end-to-end testing.
- Convert typeInfo::SpecialBinding from a struct to a class
after adding a member function.

Rework initial implementation of external I/O unit operations to
fix problems exposed in unit tests (in a later patch). Add flushing.

New<A> used to return an A&; now it returns an OwningPtr<A>
to force better ownership tracking of allocations. Its API
has also been split into New<A> and SizedNew<A> to allow
allocations with a size override.
