Fix an unlikely memory leak on conversion from string to float in the function _Py_dg_strtod() used by float(str), complex(str), pickle.load(), marshal.load(), etc. Fix an unlikely memory leak in _Py_dg_strtod() on "undfl:" label: rewrite memory management in this function to always release all memory before exiting the function. Initialize variables to NULL, and set them to NULL after calling Bfree() at the "cont:" label. Note: Bfree(NULL) is well defined: it does nothing. (cherry picked from commit 9776b06)

Fix an unlikely memory leak in _Py_dg_strtod() on "undfl:" label:
rewrite memory management in this function to always release all
memory before exiting the function. Initialize variables to NULL, and
set them to NULL after calling Bfree() at the "cont:" label.
Note: Bfree(NULL) is well defined: it does nothing.
