write_float_0. (write_float_0): New helper function.
(get_precision, select_buffer, select_string, write_float_string): New
helper functions used in remaining float writing functions. Helper function
write_float_string now contains code for writing to kind=4 character
internal units.

output_float, modified to use buffers passed in from higher functions,
builds a null terminated string of the floating point value. Character
