Drop in the latest geodesic library from GeographicLib (version 1.44).

  http://geographiclib.sourceforge.net/1.44/C/index.html

The changes are:

  - Improve accuracy of calculations by evaluating trigonometric
    functions more carefully and replacing the series for the reduced
    length with one with a smaller truncation error.

  - The allowed ranges for longitudes and azimuths is now unlimited; it
    used to be [-540d, 540d).

  - Enforce the restriction of latitude to [-90d, 90d] by returning NaNs
    if the latitude is outside this range.

  - The inverse calculation sets s12 to zero for coincident points at
    pole (instead of returning a tiny quantity).

This commit also includes a work-around for an inaccurate value for
pi/180 in dmstor.c (see the definitions of DEG_IN and DEG_OUT in
geod_interface.c).
