When reallocating an I/O buffer to accommodate a large record,
ensure that the amount of growth is at least as large as the
minimum initial record size (64KiB). The previous policy was
causing input buffer reallocation for each byte after the minimum
buffer size when scanning input data for record termination
newlines.

Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.
flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.

Two sites in io-api.cpp pass the wrong Boolean flag value to
signify that a new anonymous unit is a formatted file.

The I/O runtime library code was failing to retain data in a buffer
from the current output record when flushing the buffer; this is
fatally wrong when the corresponding file cannot be repositioned,
as in the case of standard output to the console. So refine the
Flush() member function to retain a specified number of bytes,
rearrange the data as necessary (using existing code for read frame
management after moving it into a new member function), and add
a big comment to the head of the file to clarify the roles of the
various data members in the management of contiguous frames in
circular buffers.
Update: added a unit test.

The buffer needs to be Reset() after a Flush(), since the
Flush() can be a no-op after a read->write transition.
And record numbers are 1-based, not 0-based.
This fixes a bug with rewrites of records that have been
recently read.
