MSVC does not support a distinct 80-bit extended precision
"long double" type. Rework the I/O runtime to avoid using
native C/C++ type names. Centralize the mappings between
the KIND= type parameters of REAL and their binary precisions
in the common real.h header file, and use KIND type parameter
values rather than binary precisions for clarity where
appropriate.
This patch, if successful, should obviate the need for
Differential review D88511.
(This patch anticipates a successful review of D88688, which
fixes the function that maps each kind of real to its maximum
number of significant decimal digits.)

The Fortran standard discusses BZ mode (treat blanks as zero digits)
explicitly in its effect on the editing of the digits prior to the
exponent part, but doesn't mention it in description of the
exponent part. Other compilers honor BZ mode in the exponent,
so we should do so too. So "1 e 1 " is 1.E11 in BZ mode.

It turns out that COMPLEX formatted input needs its own runtime APIs
so that null values in list-directed input skip the entire COMPLEX
datum rather than just a real or imaginary part thereof.

Allow repeated nulls in list-directed input (e.g., "4*,") and
ignore excess characters in list-directed LOGICAL input after the
T or F.
Fixes FCVS test fm923.f.

Clean up the input editing path so external input works better
when combined with further changes. List-directed input needed
to allow for advancement to following records.
