BUG: fix #4381: precision loss on string -> longdouble conversion
Avoid going through python floats when converting string to
longdouble. This makes it dramatically easier to produce
full-precision long double numbers. Fixed are the constructor
(np.longdouble("1.01")), np.fromfile, np.fromstring, np.loadtxt,
and np.genfromtxt (and functions based on it). Also fixed is
precision loss when using np.tofile.
This also fixes #1481, poor handling of bad data in fromfile
and fromstring.
If the function strtod_l is not available, almost none of this
will work, and many tests will fail.
